How to pick titanium sheet 300x100mm grade for your build
Your project's success or failure may depend on the quality of the titanium sheet 300x100mm blank that you choose. It measures 300 x 100 mm. Grade 1 is good for use in places with toxic chemicals. Grade 2 is good for most industrial and medical construction, and Grade 5 (Ti-6Al-4V) is good for high-stress aircraft projects. Before you buy something, you should make sure that the grade is right for the weather, chemicals, and load you need it to handle. After that, you should make sure that the surface treatment is correct, whether it's acid pickling, polishing, or machining. The goal of this guide is to give procurement managers and engineers a complete set of steps to follow at every choice point.
Understanding Titanium Sheet 300x100mm — Basics & Key Properties
A 300 × 100 mm flat titanium blank is in the middle of bulk coil stock and large-format plate. It is a realistic "ready-to-fabricate" starting point for prototypes and precision parts. Because of this placement, it is easy to make the blank.
Standardized Size and Thickness Range
Hot-rolled titanium sheet is made at Jucheng Titanium in a range of thicknesses, from 4 mm to 80 mm, widths from 950 mm to 2,500 mm, and lengths up to 10,000 mm. Custom cuts, like the 300 x 100 mm size, can help cut down on the amount of trash that gets sent downstream. The rules that control the business world are things like ASTM B265, ASTM F67, AMS 4911, and ASME SB265.
Mechanical Properties That Matter
It weighs about 4.51 grams per cubic centimetre, which is more than half of what steel weighs. Grade 2 titanium can be pulled apart at least 345 megapascals, and Grade 5 titanium can be pulled apart at least 895 megapascals. When Grade 2 has a stretch of at least 20%, it is guaranteed to be easy to shape over the 300 mm working length. The exact rules for the ASTM B265 test are where these numbers come from.
Surface Condition and State
Before leaving the building, sheets are rolled, heated, levelled, pickled, and given a smooth finish on the outside. When the sheets leave, they are all in an annealed state. Some surface processes are acid cleaning, grinding (with a Ra value less than 0.8 µm), and cutting. In the annealed state, leftover stress is reduced, which is very important when very small blanks need to have very tight size limits.
Key Criteria for Choosing the Right Titanium Sheet Grade
Aside from unit price, the choice of grades is based on things like the surroundings, the motor load, and the overall cost of ownership. Here is a list of the grades of Jucheng Titanium stocks and the uses that are best for them.
Commercially Pure Grades: Gr1, Gr2, Gr4
- Grade 1 is highly sought after because it is the purest, can be cold formed best, and is resistant to oxidising acids the best. It can be used for electrical tools and medical products where there is a lot of shaping to do.
- Score 2 is the CP score that people ask for the most. Because it is both very strong (at least 345 MPa UTS) and easy to weld, it is now the best choice for heat exchangers, chemical reactors, and other industrial construction projects.
- Grade 4 is used for surgical devices and medical equipment that has to hold weight. It must also meet ASTM F67 guidelines for biocompatibility. With a UTS strength of 550 MPa or more, it is the strongest grade of CP.
The two main types of titanium sheet 300x100mm used for chemical processing and building medical devices are grades 1 and 2. People use Grade 4 when they need to make something stronger without adding any alloying materials.
High-Performance Alloys: Gr5, Gr7, Gr9, Gr12
- The aerospace industry set the standard for Grade 5 (Ti-6Al-4V), which is the same as AMS 4911. The wear resistance is good, and the tensile strength is at least 895 MPa. It is best to warm-form the metal, and the bend radius should be at least 4 to 5 times the thickness.
- It is the most resistant to rust of all the titanium grades when it comes to lowering acids like hydrochloric and sulphuric acid streams. This is because 0.12–0.25% palladium has been added to Grade 2 titanium to make it stronger.
- Grade 9 (Ti-3Al-2.5V) is a grade that is in the middle of CP grades and Grade 5. This material is often used for sports gear and hydraulic tubes, both of which need to be moderately strong and easy to weld.
- In particular, grade 12 (Ti-0.3Mo-0.8Ni) is best for use in chemical service settings at high temperatures and in marine settings. Because it has nickel and molybdenum added to it, it is better at resisting crevice corrosion at higher temperatures.
Each grade of alloy was made to fill a certain need. If you choose the wrong one, like if you use Grade 2 in a strong stream of reducing acid instead of Grade 7, the equipment could rust quickly and break down early.
Thickness, Finish, and Cost Trade-offs
Under AMS 2631, sheets that are larger than 20 millimetres must be tested with ultrasound waves to find any internal breaks. It takes longer and costs more to use polished surfaces, but they make it less likely that fatigue fractures will form when loads are applied and removed repeatedly. For most chemical and industrial uses, acid-pickled finishes are the norm because they are very cheap. The surface fatigue needs of the job should always be taken into account along with the finish specification.
Practical Comparison: Titanium Flat Stock vs. Other Metal Sheets
It's interesting to many procurement teams to know why titanium flat stock costs more than stainless steel or aluminium. The price at which it was bought and how much it will cost over time affect the result.
Titanium vs. Stainless Steel
There are 7.98 grams of steel 316L in every cubic centimetre, which is almost twice as much as there is titanium. It does, however, cost a lot less per kilogram. When it comes to aircraft or mobile chemical units that need to be light, titanium's structural weight savings are enough to cover its direct costs. Titanium also doesn't crack when it comes to chloride stress corrosion, which is a common way for stainless steel to break in salty and marine environments. Titanium also doesn't need any other surface treatment besides the inactive layer of titanium oxide.
Titanium vs. Aluminum
Aluminium is easy to make and weighs 2.70 grams per cubic centimetre. However, it can only handle temperatures up to 150 degrees Celsius, so it can't be used for high-temperature processing. Metals like aluminium break down quickly in salty or acidic environments, but titanium stays strong above 300 degrees Celsius and doesn't pit in those circumstances. Titanium is the scientifically correct choice for structural panels used in spacecraft and wetted surfaces used in chemical processes, even though it costs more at first.
Sheet vs. Plate — Which Form Factor Is Right?
Titanium sheet 300x100mm can be used for prototyping, making small batches of medical parts, and making precise instrument parts. For pressure tanks, structural frames, and heavy heat exchanger tube sheets, plates that are more than 25 millimetres thick are a good choice. Because titanium tends to work harder over time, when the form factor is right for the job, the time it takes to machine goes down and the tool lasts longer.
How to Procure Titanium Flat Stock — Best Practices for B2B Buyers
If you buy titanium sheet from a source that isn't certified, there's a chance that the sheet can't be tracked back to its source, which could mean that the certification of later parts isn't real. As long as you follow these steps, your purchase will be safe.
Verify Certification and Standards Compliance
You should need Mill Test Certificates (MTC) that follow the rules in EN 10204 3.1. The paper needs to have the heat number, the chemical makeup that has been proven using ICP or OES spectroscopy, the tension and bend test results, and the right standard, which could be ASTM B265, AMS 4911, ASME SB265, or ASTM F67 for medical grades. Chemical elements like hydrogen, nitrogen, iron, and oxygen must meet the intermediate limits of the ASTM B265 standard in order to keep the material from becoming weak.
Confirm Custom Cutting and Minimum Order Terms
Not all providers offer small-format cuts because they are more cost-effective. As per ASTM B265, make sure the maker can provide blanks with certain sizes, specs, and flatness (with a difference of less than three millimetres along a 300-millimeter length). If you want to plan your cash flow well, you should find out what the minimum order quantities are for trial runs and production amounts.
Evaluate Delivery Time and Inventory Depth
Lead time has a direct effect on how jobs are scheduled. Standard grades can be shipped in days instead of weeks because suppliers keep huge stock levels. For example, Jucheng Titanium keeps about 3,000 tonnes on hand all year long. Before you sign a long-term contract, you should find out more about Incoterms, the paperwork that is needed for export, and whether the supplier has experience with US import compliance.
Step-by-Step Grade Selection for Your Build
If you use a decision-making process that you can use again and again, you won't have to guess, and you'll be less likely to over-specify (and spend too much on) things that your application doesn't need.
- It is important to describe the working setting, which includes the highest temperature that can be reached, the chemicals that are used, and whether salt or reducing acids are present or not.
- Figure out what the mechanical load needs to be, such as the tensile strength, the number of wear cycles, and whether more shaping or welding needs to be done after delivery.
- If you want to narrow down the candidates to just two, use the grade comparison that was shown earlier.
- Make sure the surface treatment is right. For normal industry use, pickled is best, while polished is best for areas that need to be kept clean or that are prone to stress.
- Before the whole order is sent out, you should ask for an MTC and a sample. Then, you should compare the chemical makeup and mechanical test results to the standards in your design.
- Check how reliable the provider is by looking at how much experience they have with exporting, what kinds of certifications they have, and how much stock they have.
Conclusion
Selecting the correct titanium sheet 300x100mm flat stock grade is a structured technical decision. Grade 2 covers most industrial builds; Grade 5 handles high-stress aerospace structures; Grade 7 protects against reducing acids; Grade 12 suits hot seawater service. Confirm surface treatment, ASTM compliance, and MTC documentation before order placement. A supplier with deep inventory, custom cutting capability, and 20-plus years of titanium processing experience substantially reduces procurement risk and project timeline. Match your grade to your environment, verify your certification chain, and your build will perform as designed.
FAQ
1. What thickness options are available for titanium flat blanks?
Jucheng Titanium produces hot-rolled titanium sheet from 4 mm to 80 mm thick, with widths from 950 mm to 2,500 mm and lengths up to 10,000 mm. Custom dimensions, including small-format 300 × 100 mm blanks, are available on request to reduce material waste for precision machining operations.
2. How does corrosion resistance differ across grades?
Grade 1 and Grade 2 resist oxidizing environments well. Grade 7 adds 0.12–0.25% palladium to provide resistance in reducing acids like HCl and H₂SO₄ — environments where CP grades would corrode. Grade 12 adds nickel and molybdenum for elevated-temperature seawater and crevice corrosion resistance. Matching the grade to the chemical environment is the single most important corrosion-protection decision.
