SUS420 stainless steel is a martensitic stainless steel with certain wear resistance, corrosion resistance and high hardness.
SUS420 stainless steel belongs to SUS420 "cutting tool grade" martensitic steel, similar to the early high chromium steel stainless steel. It is suitable for general working environments that require stainless steel. SUS420 stainless steel is suitable for various precision machinery, bearings, electrical equipment, instruments and meters, measuring tools, transportation tools, household appliances and other fields.
The mechanical properties of SUS420 stainless steel are as follows:
Tensile strength σb (MPa): quenched and tempered, ≥635
Yield strength σ0.2 (MPa): quenched and tempered, ≥440
Elongation δ5 (%): quenched and tempered, ≥20
Sectional shrinkage ψ (%): quenched and tempered, ≥50
Impact energy Akv (J): quenched and tempered, ≥63
Hardness: annealed, ≤223HB; quenched and tempered, ≥192HB
The product specifications of SUS420 stainless steel bars are varied. Common specifications include diameter and length. The diameter is usually between 2 mm and 300 mm, and the length can be customized according to customer needs. In addition, surface treatments such as brightening and pickling can be performed according to the requirements of specific applications.
