Product Overview
Stainless Steel 310 is a high-chromium, high-nickel austenitic stainless steel designed for use in high-temperature applications where excellent oxidation resistance and high strength are required. Grade 310S is the low-carbon version, which is less prone to embrittlement and sensitization in service. Grade 310H is used for high creep strength. Because of its high chromium and nickel content, SS 310 provides excellent resistance to corrosion and is superior to SS 304 or 309 in most environments. It is extensively used in furnace parts, heat treatment equipment, and chemical processing.
Key Advantages & Features
Extreme Heat Resistance
Provides excellent oxidation resistance in continuous service up to 1150°C.
High Alloy Content
25% Chromium and 20% Nickel content ensure superior structural stability.
Non-Magnetic Nature
Maintains non-magnetic properties in both annealed and cold-worked conditions.
