Stainless Steel Rectangle Bar 420

Stainless Steel Rectangle Bar 420

420 stainless steel rectangle bar is a martensitic alloy known for its high hardness, strength, and excellent wear resistance. With added carbon and chromium, this grade delivers strong mechanical performance for components that must withstand friction, impact, and repeated use. While its corrosion resistance is lower than austenitic grades, 420 is ideal for applications requiring strength and durability – such as shafts, guides, bearings, valve parts, and structural components across industrial and mechanical systems.



Applications: Shafts, guides, bearings, valve components, wear resistant parts, structural components.
Available Alloys: 420 Stainless Steel
