420 Stainless Steel Seamless Pipe

Grade: 420/S42000

Size:

Seamless: 6mm*1mm-720mm*50mm

Coiled: 4mm*0.5mm-32mm*3mm

Standard: ASTM A312, ASTM A213 etc.

Surface: No.1(Pickling), Bright(Polished)

420 Stainless Steel Pipe is a martensitic chromium stainless steel designed for a useful combination of hardness, strength, wear resistance, and moderate corrosion resistance. Its properties can be significantly increased through quenching and tempering. 420 is suitable for valve components, pump parts, shafts, mechanical tubing, tools, and wear-resistant components where higher hardness is required than conventional ferritic or austenitic stainless steels.
