Is 420 stainless steel magnetic?

420 is a stainless steel material with excellent mechanical properties, corrosion resistance and wear resistance.

Mechanical properties:
The tensile strength of SUS420 after heat treatment is 700-1100MPa, the yield strength is 540-850MPa, and the elongation is ≥12%.

Corrosion resistance:
SUS420 has good corrosion resistance and can maintain stable performance in various environments such as water, steam, grease and chemicals. In addition, the material is heat-resistant and wear-resistant, and is suitable for environments working under high temperature and high pressure.

Wear resistance:
SUS420 has excellent wear resistance and is suitable for manufacturing mechanical parts and tools that require high hardness and wear resistance. The material is very useful in manufacturing tools such as saw blades, cutters and needles.

Is it magnetic?
SUS420 is magnetic and can be used to manufacture magnetic parts and equipment. The reason why SUS420 is magnetic is that it contains iron. Iron is a ferromagnetic substance whose atoms are magnetic and can align under an external magnetic field. The iron elements in SUS420 are aligned, making the whole alloy magnetic.

GNEE delivery shape and specifications:
SUS420 can provide delivery shapes including wire, plate and bar. Its specifications can be customized according to customer requirements. Common specifications are round bars and plates with sizes of 6-300mm. In addition, the material can also be used to manufacture various tools, knives and mechanical parts.

Delivery hardness and hardness after heat treatment:
The hardness of SUS420 depends on the state after heat treatment. In the annealed state, the hardness of the material is ≤235HB. After quenching and tempering, its hardness can reach HRC50-52, which is suitable for manufacturing high-strength mechanical parts and tools.
