How about stainless steel 2520 and 316?
316 stainless steel by adding Mo element, the corrosion resistance, and high temperature strength has greatly improved, high temperature can reach 1200-1300 degrees, can be used in severe conditions. Uses: marine equipment, chemicals, dyes, paper, oxalic acid, fertilizer and other production equipment; photography, food industry, coastal facilities, ropes, CD poles, bolts, nuts.
Their nickel content is different. 2520 contains about 20 nickel, 316 contains about 13 nickel, and contains 2 molybdenum.
2520 stainless steel (310S) austenitic chromium nickel stainless steel has good oxidation resistance, corrosion resistance, because of higher content of chromium and nickel content, which has high temperature creep strength, can continuously work under high temperature, good heat resistance. For Ni (Ni), chromium (Cr) content is high, with good oxidation resistance, corrosion resistance, acid and salt, high temperature performance, high temperature resistant steel dedicated to the manufacture of electric furnace tube and so on, increase the amount of carbon austenitic stainless steel, due to the solid solution strengthening effect to the strength improved, chemical composition characteristics of austenitic stainless steel is chrome, nickel based addition of molybdenum and tungsten, niobium and titanium elements, as its face centered cubic structure, and strength and high creep strength at high temperature.
