310S STAINLESS STEELPLATE

Grade 310/310S stainless steel (1.4845) is one of the most widely used grades of heat resistant stainless steel supplied into numerous industry sectors.

Q: What is the core chemical composition of 310S stainless steel plate?

A: 310S (UNS S31008, EN 1.4845) is an austenitic stainless steel with key components: Cr 24.0-26.0%, Ni 19.0-22.0%, C ≤ 0.08%, and high Fe content. It contains no Mo, with Si ≤ 1.5% and Mn ≤ 2.0%.

 

Q: What are the primary performance characteristics of 310S stainless steel plate?

A: It offers excellent high-temperature oxidation resistance (up to 1150°C), good corrosion resistance to acids/bases, high toughness, non-magnetism, and excellent weldability. It maintains structural stability under prolonged high-temperature service.

 

Q: What are the typical applications of 310S stainless steel plate?

A: Common uses include high-temperature equipment components such as furnace liners, heat exchanger tubes, boiler parts, chemical reactor vessels, and exhaust systems in aerospace/automotive industries.

 

Q: What are the standard thickness and size ranges for 310S stainless steel plate?

A: Thickness: 0.3-100mm (customizable for thicker plates). Common sizes: 1220×2440mm, 1500×3000mm, 2000×6000mm. It complies with ASTM A240, EN 10088-2, and GB/T 4237 standards.

 

Q: How does 310S differ from 304/316L stainless steel plates, and when to choose 310S?

A: 310S has higher Cr/Ni content than 304/316L, offering superior high-temperature resistance (304/316L max 870°C vs. 310S 1150°C). Choose 310S for applications involving continuous high temperatures, oxidation, or thermal cycling-304/316L are better for general corrosion resistance at room temperature.
