420 431 stainless steel pipe

Product description

420 stainless steel is a martensitic stainless steel, belonging to the high carbon grade. Under hardened conditions, it has good resistance to the atmosphere, has certain wear resistance and corrosion resistance, and has high hardness. It is suitable for various precision machinery, bearings, electrical, equipment, instruments, meters, transportation vehicles, household appliances, as well as food tableware, stainless steel hospital equipment, etc. 420 stainless steel that has passed the GB4806.9-2016 national food safety standard test can meet the food grade standard.
431 stainless steel is a metal material, martensitic stainless steel standard AISI, ASTM type, model 431, UNS number S43100

431 Chinese name is martensitic stainless steel, Ni-containing Cr steel, high mechanical properties can be obtained through heat treatment, and corrosion resistance is better than 410 steel and 430 steel. 431 stainless steel corresponds to China 1Cr17Ni2 and Japan JIS SUS431.

431 stainless steel has high strength, but poor plasticity and weldability. Common grades of martensitic stainless steel include 1Cr13, 3Cr13, etc. Due to its high carbon content, it has high strength, hardness and wear resistance, but its corrosion resistance is slightly poor. It is used in springs, turbine blades, hydraulic valves and other parts with high mechanical properties and general corrosion resistance requirements, and is used after quenching and tempering. Annealing treatment is required after forging and stamping.
