Description

Leading Supplier of High Performance Stainless Steel

Specification of 420 Stainless Steel also equivalent to 

  • 1.4021 |  1.4028 | 1.4034 | 1.2083 | ASTM A276 | S42000 | 
    BS EN 10088 | AISI BS970 | UNS X20Cr13 |  X30Cr13
  • Japan Spec : 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.

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

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.

Annealing

Annealing of this material can be performed by heating uniformly to 840-900°C (1544-1652°F) and held until the temperature is uniform throughout the section. Soaking and cooling is required.

Heat Treatment

Stainless steel grade 420J2 has to be heated uniformly to 730-790°C (1346-1454°F) and held until temperature is uniform throughout the section.

Hardening

Stainless steel grade 420J2 can be hardened by heating 950-1020°C (1742-1868°F) and held until temperature is uniform throughout the section. This should be followed by quenching in oil or air cooling. Tempering should be done when it is slightly warm.

Applications

Stainless steel grade 420J2 is used in the following application areas:

  • Surgical instruments
  • Daggers and swords
  • Budget knives and diving knives
  • Haircutting scissors and domestic scissors
