Renowned for its exceptional high-temperature oxidation resistance, corrosion resistance, and mechanical stability, 310 stainless steel plate is the go-to choice for industries demanding reliability under harsh operating conditions. This versatile alloy, also known as 2520 stainless steel, delivers consistent performance in heat treatment, chemical processing, power generation, and aerospace applications, making it a cost-effective solution for critical industrial projects.

Materials and Chemical composition

310 stainless steel plate is an austenitic stainless steel with a high chromium (24-26%) and nickel (19-22%) content, forming a stable oxide layer that provides superior protection against oxidation and corrosion. Unlike standard stainless steel grades like 304 or 316, its enhanced alloy composition enables it to withstand prolonged exposure to high temperatures up to 1150°C (2100°F) in continuous service and 1035°C (1900°F) in intermittent service. It is non-magnetic and exhibits excellent workability, allowing for cold forming, welding, and machining with proper techniques.

Mechanical Properties

310 stainless steel plate maintains excellent mechanical strength and ductility even at elevated temperatures, making it suitable for load-bearing high-heat applications. All values are based on plates in the solution-annealed and pickled condition (standard delivery state for sheets/plates).
