1. Type of 2520 stainless steel grade
2520 stainless steel is an abbreviation for China's stainless steel standard.
2520 Chinese Standard
Old grade: 0Cr25Ni20 (GB/T3280-1992)
New grade: 06Cr25Ni20 (GB/T20878-2007)
China Uniform Digital Code: S31008 (GB/T20878-2007)
2. The main properties of 2520 stainless steel
Due to 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 tubes are specially used for the manufacture of electric heating tubes, etc., and carbon is added to austenitic stainless steel. After the content, the strength is improved by the solid solution strengthening effect. The chemical composition of the austenitic stainless steel is based on chromium, nickel and other elements such as molybdenum, tungsten, niobium and titanium. Since the structure is a face-centered cubic structure, Thus there is high strength and creep strength at high temperatures. 2520 stainless steel material has 2520 stainless steel plate, 2520 stainless steel rod, 2520 stainless steel tube, 2520 stainless steel angle steel, 2520 stainless steel flat steel, round steel, stainless steel plate, stainless steel rod, stainless steel tube, which can work at a high temperature of 1250 degrees for a long time.
3. Physicochemical properties and mechanical properties of 2520 stainless steel
1. Physical and chemical properties
It has high high temperature strength and oxidation resistance, and is sensitive to sulfur-containing atmosphere. It has a brittle tendency of precipitated phase at 600-800 °C, and is suitable for making various furnace components subjected to stress.
2, mechanical properties
Tensile strength σb (MPa): ≥ 590 Conditional yield strength σ0.2 (MPa): ≥ 295 elongation δ 5 (%): ≥ 35 section shrinkage ψ (%): ≥ 50 hardness: ≤ 187H
