Dongguan total fat Metal Materials Co., Guangdong is the most professional 420J2 stainless steel manufacturers. 420J2 grades for the corresponding domestic 3Cr13; 420J2 chemical composition (content%): C: 0.26 ~ 0.35; Mn≤1; Si≤1; Cr12.00 ~ 14.00; Ni≤0.60; S≤0.030; P≤0.035; 420J2 heat treatment: Bars and forgings: 1000 ~ 1050 ℃ oil quenching or air cooling, 200 ~ 300 ℃ tempered. Plate: 740 ~ 780 ℃ annealing or tempering. Oxidation resistance: a stable oxidation resistance below 700 ℃. Special Requirements: The steel should not be tempered at a temperature range of 350-550 ℃. Our parent material 420J2 are imported or domestic large steel materials, performance and stability Langfang 304 stainless steel stamping, processing performance in the market by the praise, welcome customers to order or inquire. 420J2 stainless steel factory in Dongguan City of total fat Metal Materials Co., Ltd. is the most professional Guangdong 301 stainless steel with 1 / 2H. 301 stainless steel is a metastable austenitic stainless steel stamping Langfang 304 stainless steel, the full solution under conditions in Langfang 304 stainless steel stamping, with fully austenitic structure. In austenitic stainless steel, 301 is most likely to strengthen the cold deformation of steel, by cold deformation processing so that the intensity of steel, hardness, and retain enough plastic, toughness, coupled with this steel has good resistance to atmospheric conditions rust, but reducing media poor in corrosion resistance, poor in acid salt and other chemical medium corrosion resistance and is not recommended for harsh corrosive environments. 202 stainless steel stamping, stainless steel stamping Langfang, were issued by the City of stainless steel with a total fat Metal Materials Limited. Dongguan total fat Metal Materials Co. (www.dggongfa.com) (www.dggongfa.com) strong, credible, and stainless steel products and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead a total of hair metal into the brilliant and you work for a better future!
