310S stainless steel pipe description
Stainless Steel Pipe 310S Stainless Steel Pipe 310SStainless Steel Seamless Pipe 2520 Stainless Steel Welded Pipe
310S (old brand 0Cr25Ni20/new brand 06Cr25Ni20) is an austenitic chromium nickel stainless steel with good oxidation resistance and corrosion resistance. Because of the high percentage of chromium and nickel, 310S has much better creep strength, can continue to operate at high temperatures, and has good high temperature resistance.
310S stainless steel is austenitic chromium nickel stainless steel, which has good oxidation resistance, corrosion resistance and high temperature resistance. Because of the high percentage of chromium and nickel, it has much better creep strength, can continue to operate at high temperatures, and has good high temperature resistance. Because of the high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance, and high temperature resistance. High temperature resistant steel pipes are specially used for making electric furnace tubes and other occasions. After the carbon content is increased in austenitic stainless steel, its strength is improved due to its solid solution strengthening effect. The chemical composition of austenitic stainless steel is characterized by adding molybdenum, tungsten, niobium, titanium and other elements based on chromium and nickel. Because its structure is face centered cubic structure, Therefore, it has high strength and creep strength at high temperature. The melting point is 1470 ℃, the softening starts at 800 ℃, and the allowable stress continues to decrease.
310S (0Cr25Ni20/0Cr25Ni20Si2), heat-resistant stainless steel, domestic brand 0Cr25Ni20, American brand SA213/TP310S, commonly known as 310S, also known as 2520, duplex stainless steel, is used for manufacturing high-temperature furnace tubes. Chemical composition of
SA213/TP310S (%):
Ni: 19.00-22.00
Cr Cr: 24.00-26.00
Si Si<=1.50
Mn Mn<=2.00
