Commonly used in boiler, chemical industry and other industries. Compared to 309S, 309 does not contain any sulfur (S) content.The equivalent grade in China is 06Cr25Ni20, which is called 310s in the United States and belongs to AISI and ASTM standards. It also complies with JIS G4305 standard "sus" and European standard 1.4845. This chromium-nickel austenitic stainless steel, known as 310s, exhibits excellent resistance to oxidation and corrosion. Its high chromium and nickel content contributes to its excellent creep strength, allowing it to operate at high temperatures with minimal deformation. In addition, it also exhibits good high temperature resistance.310S : 1) Good oxidation resistance; 2) Use a wide range of temperature (below 1000 ℃); 3) Nonmagnetic solid solution state; 4) High temperature high strength; 5) Good weldability. 309S : The material can withstand multiple heating cycles up to 980°C. It has superior strength and oxidation resistance, and also has excellent performance in high temperature carburizing environment.

310S: 310S stainless steel is an essential material in aerospace, chemical and other industries, and is widely used in high temperature environments. Some of its important applications include exhaust pipes, tubing, heat treatment furnaces, heat exchangers, incinerators and high temperature contact parts. Specifically, 310S stainless steel is used in exhaust systems of automobiles, aircraft, and industrial equipment due to its high temperature resistance. It is also used in heat treatment furnaces to aid in the construction of heating elements and radiant tubes. Additionally, 310S is used in the manufacture of heat exchangers designed to withstand corrosive environments and high temperature gases or liquids. In the waste treatment industry, 310S stainless steel is the material of choice for constructing incinerators due to its durability and ability to withstand extremely hot and corrosive gases. Finally, in applications where components are in direct contact with high temperatures, such as kilns, ovens, and boilers, 310S stainless steel is trusted for its excellent resistance to thermal fatigue and oxidation. Overall, 310S stainless steel plays a key role in high temperature environments with excellent heat resistance and corrosion resistance. Its widespread use in aerospace, the chemical industry, and other fields demonstrates its importance as the material of choice for harsh high-temperature environments. 309S: The material known as 309s is specifically designed for use in furnaces. Widely used in boilers, energy power generation (such as nuclear power, thermal power, fuel cells), industrial furnaces, incinerators, heating furnaces, chemical and petrochemical industries. It is highly valued and utilized in these important areas.The corresponding grade of 309S in China is 06Cr23Ni13. In the US it is known as S30908 and complies with AISI and ASTM standards. It also complies with JIS G4305 standard su and European standard 1.4833. 309S is a free-machining and sulfur-free stainless steel. It is typically used in applications requiring a free cut and a clean finish. Compared to 309 stainless steel, 309S has a lower carbon content, making it suitable for welding applications. The low carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld. However, under certain circumstances, such as weld erosion, there is a possibility of intergranular corrosion in stainless steel due to carbide precipitation.
