310/310S Stainless Steel - Complete Material Specifications & Properties

Abhinav Overseas offers premium quality Stainless Steel 310 and 310S, which are high-chromium, high-nickel austenitic stainless steels engineered for extreme high-temperature environments. These grades provide exceptional oxidation resistance and thermal stability up to 1100°C, making them ideal for demanding industrial applications.

Our SS 310/310S products feature excellent resistance to thermal cycling, scaling, and creep at elevated temperatures. The primary difference between the two grades is the carbon content—310S has a lower carbon level (≤0.08%) to enhance weldability and reduce the risk of carbide precipitation in welded structures.

We supply these high-performance alloys in various forms including sheets, plates, pipes, tubes, bars, and custom fabricated components to meet specific industry requirements. Each product undergoes rigorous quality testing to ensure compliance with international standards.

As a trusted supplier in the metal industry, we provide competitive pricing, prompt delivery schedules, and technical expertise to help you select the right material grade for your high-temperature applications in petrochemical, power generation, and industrial furnace environments.
