Grade Overview

SS 420 / 420J1 / 420J2 Sheet — Grade Overview

SS 420 / 420J1 / 420J2 are martensitic stainless steel sheets known for their high hardness, strength, and good corrosion resistance in mild environments. SS 420 is a chromium-based stainless steel that can be heat-treated to achieve high hardness. Variants 420J1 and 420J2 differ mainly in carbon content, with 420J2 offering higher hardness and wear resistance.

Composition Analysis

Metallurgical Characteristics of SS 420 / 420J1 / 420J2 Sheet

Each element plays a precise role in delivering the high hardness, strength and durability of the SS 420 series.

C
Carbon
Increases hardness and strength. Higher carbon improves wear resistance and hardenability. (420J2 has higher carbon than 420J1, giving higher hardness.)
Cr
Chromium
Provides corrosion and oxidation resistance by forming a passive protective layer on the surface.
Mn
Manganese
Improves strength and toughness; helps improve hot working properties.
Si
Silicon
Enhances strength and oxidation resistance; acts as a deoxidizer during steelmaking.
P
Phosphorus
Improves machinability but can reduce ductility and toughness if excessive.
S
Sulfur
Improves machinability; too much may reduce toughness and corrosion resistance.
Fe
Iron
Base metal forming the primary structure of the alloy.
