What Are The High Temperature Resistant Stainless Steels?

Aug 04, 2021

High-temperature stainless steel grades: 310S, 06Cr25Ni20, 16Cr25Ni20Si2, 309S, 16Cr20Ni14Si2, 253MA, S30815, 314, 347, 436L, etc.


Products Range: stainless steel plates, stainless steel coils, wires, bars, ss strip, ss tube, etc.


Size: can be customized according to customer requirements.


Below we mainly introduce two materials, 309s stainless steel and 310s stainless steel


309S and 310S austenitic stainless steels are often used in high-temperature environments. Its high chromium content and nickel content ensure good corrosion resistance and oxidation resistance. Therefore, they are widely used in furnace parts in the heat treatment industry, such as conveyor belts, drums, furnace heads, refractory pads, pipe hangers, etc. These grades are also used in the chemical processing industry to carry hot concentrated acids, ammonia and disulfides. In the food processing industry, these grades are used in contact with hot acetic acid and citric acid.


309S (23Cr-13Ni) stainless steel has excellent corrosion resistance and strength, and is suitable for parts with a working temperature of 1000°C. Because of this high-temperature resistance, it is also called: high-alloy stainless steel, which has excellent high-temperature acid resistance and high-temperature strength. Its use is generally widely used in exhaust machines, heat treatment furnaces and heat exchangers.


309S, the national standard brand is: 0cr23ni13, and the usable temperature is 900~1000 degrees Celsius.


310S stainless steel is suitable for making various furnace components, with a maximum working temperature of 1200°C and a continuous use temperature of 1150°C. It is the mainstream steel of the heat-resistant steel series, and the maximum working temperature of 309S is 1050℃, and it can be used for a long time with a large load at 650-700℃.

310S, the national standard number is 0cr25ni20si2, and the usable temperature is between 1000°C and 1200°C.


310S stainless steel is widely used as a stainless steel pipe. It is widely used as a pipeline for conveying fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used Used in the manufacture of mechanical parts and engineering structures. It is also often used to produce various conventional weapons, barrels, and shells.
