SS 310 vs SS310S Stainless Steel Plate: High Temperature Resistance
Gadewch neges
In industries such as petrochemical, power generation, furnace manufacturing, and heat treatment, selecting the right high-temperature stainless steel plate is critical. SS 310 and SS310S stainless steel plates are widely recognized for their exceptional resistance to heat and oxidation, making them ideal choices for extreme environments.
This article provides detailed industry knowledge to help engineers, procurement professionals, and project managers make informed decisions.
What is the difference between SS 310 and ss310s?
Grade 310 stainless steel is a medium-carbon austenitic stainless steel suitable for high-temperature applications, such as furnace components and heat-treating equipment. It can operate continuously up to 1150℃ and intermittently up to 1035℃. Grade 310S stainless steel, on the other hand, can operate continuously up to 1150℃ (2100℃F) and intermittently up to 1040℃ (1900℃F). This high-temperature resistance is due to its composition of approximately 25% chromium and 20% nickel.

What is the temperature range for SS 310S?
Hot Working: Hot forging of 310 grade steel occurs in the temperature range of 975-1175℃.
Cold Working: 310 grade steel can be cold worked by stamping, drawing, upsetting, and other methods. Annealing: Annealing is performed by heating to a temperature range of 1040-1065℃.
What is the difference between SS 310 and ss309?
Stainless Steel 309: It is suitable for high-temperature applications, but not as high as Stainless Steel 310. It has a maximum operating temperature of around 980℃ (1800℃F). Stainless Steel 310: It is specifically designed for high-temperature applications and can withstand temperatures up to 1150℃ (2102℃F).
What is the hardness of 310 stainless steel?
310, 310S and 310H all have a minimum yield strength of 30 ksi and an elongation of 40%. On the Brinell hardness scale they all have a hardness of 217, and on the Rockwell B scale, they have a hardness of 95.
