Frequently Asked Questions (FAQ)
1. What is ASTM A240 316Ti stainless steel plate?
ASTM A240 316Ti is a titanium-stabilized austenitic stainless steel plate that offers excellent corrosion resistance, improved weldability, and superior high-temperature performance. It is commonly supplied as Hot Rolled Stainless Steel Plate with a No.1 Finish.
2. What is the difference between 316 and 316Ti stainless steel?
The primary difference is the addition of titanium in 316Ti Stainless Steel. Titanium helps prevent carbide precipitation during welding, providing better resistance to intergranular corrosion and making 316Ti more suitable for prolonged service at elevated temperatures.
3. What does UNS S31635 and EN 1.4571 mean?
UNS S31635 is the Unified Numbering System designation used in North America, while EN 1.4571 is the European material number. Both refer to the internationally recognized 316Ti stainless steel grade.
4. What surface finish is available for hot rolled 316Ti stainless steel plates?
The standard finish is No.1 Finish, produced through hot rolling, annealing, and pickling. Additional finishes and custom processing are available based on project requirements.
5. Is 316Ti stainless steel suitable for petrochemical applications?
Yes. ASTM A240 316Ti Hot Rolled Stainless Steel Plate is widely used in petrochemical plants because of its excellent resistance to corrosive chemicals, chlorides, and high-temperature environments.
