What is SUS420J2?

Stainless steel grade 420J2 is inexpensive and highly corrosion resistant steel. It has good corrosion resistance in mild atmosphere as well as domestic and industrial environments. It is also resistant to dilute nitric acid, carbonic acid, ammonia, crude oil, detergent solutions, vinegar, food acids, several petroleum products, and steam.

Stainless steel grade 420J2 is known to possess good strength and reasonable impact resistant properties in hardened and tempered conditions when compared with 440 grades.

420 stainless steel Chemical Composition

The chemical composition of stainless steel grade 420J2 is outlined in the following table.

Element Content (%)
Chromium, Cr 14
Nickel, Ni (optional) 1
Manganese, Mn 1
Silicon, Si 1
Phosphorus, P 0.04
Carbon, C 0.15-0.36
Sulfur, S 0.03
Iron, Fe Balance

 Welding of stainless steel 420j2

Welding of stainless steel grade 420J2 is easy. It is recommended that welding in annealed or hardened and tempered conditions should be avoided as it causes formation of brittleness, resulting in cold cracking due to contraction stresses.

Pre-heating and inter-pass temperature control during welding, followed by very slow cooling and post-weld annealing are good measures to take to prevent cracking.

Is 420J2 stainless steel good?

Stainless steel grade 420J2 is inexpensive and highly corrosion resistant steel.  Stainless steel grade 420J2 is known to possess good strength and reasonable impact resistant properties in hardened and tempered conditions when compared with 440 grades.
What is Japanese steel 420J2?
420j2 stainless steel contains medium quality carbon content.  It has good corrosion resistance in salt-free atmospheres and in most industrial environments. It is resistant to many chemicals and household cleaners; and, it is also a more durable steel compared to the 440 grades.
