The difference between 309S stainless steel strips and 310S stainless steel strips high temperature resistance:
309S stainless steel strip and 310S stainless steel strip are commonly used products in various industries around the world.
309S stainless steel strip is an austenitic chromium-nickel stainless steel that provides excellent corrosion and heat resistance for many critical applications, 309S stainless steel strip is high in chromium and low in nickel and can be used in atmospheres with the highest sulfur content , heat-resistant temperature of 1000 degrees.
310S stainless steel strip is austenitic chromium-nickel stainless steel with excellent resistance to oxidation and oxidation, corrosion resistance and high temperature resistance. Due to the high content of chromium and nickel, the strength is much better, it can work continuously at high temperature, and has good high temperature resistance. It also has good oxidation resistance, corrosion resistance, acid and alkali resistance, high temperature resistance and other characteristics. 310S stainless steel strip is specially used to make furnace tubes. Austenitic stainless steel has added carbon content, which increases strength due to solid solution strengthening, so it has high strength at high temperature. The melting point starts to soften at 1470°C, and the allowable stress continues to decrease at 800°C.
309S stainless steel strips and 310S stainless steel strips application difference:
309S stainless steel strips is used in:
Blast furnaces, fluidized bed furnaces, paper mill equipment, catalyst recovery systems and recovery units, pulverized coal burners and tube racks, annealing covers and boxes, incinerators, rotary kilns and calciners
310S stainless steel strips is used in:
Fluidized bed coal burners, radiant welded tubes, tube hangers for oil refining and steam boilers, gas generator internals, thermowells and refractory parts, burners, combustion chambers, retorts, muffles, annealing caps, cryogenic structures .
The above is the difference between 309S and 310S stainless steel.
