Stainless steel 1.4028 420B

Everything you need to know about corrosion-resistant martensitic stainless steel X46CR13, 1.4028 420B, S42020, according to EN 10088-1, ISO 4957

What is Grade 1.4028 420B Stainless Steel?

Grade 1.4028 420B stainless steel is chromium martensitic steel. Although this type of steel contains an average of 13% chromium, it does not contain any nickel. The carbon content in the chemical composition of stainless steel 1.4028 420B characterizes it and gives it high strength

Grade 1.4028 420B stainless steel has the following properties:

  1. Low corrosion resistance
  2. Low embodied energy
  3. More hard enable than 1.4021
  4. Ferromagnetic

Why use stainless steel 1.4028 420B?

Grade 1.4028 420B stainless steel contains a higher carbon content. Due to this chemical composition, the stainless-steel type has higher strength and is therefore easier to harden.

Although steel has poor corrosion resistance, Grade 1.4028 420B stainless steel performs well at room temperature in contact with some carbonates, acetates and hydroxides.

What is the chemical composition of stainless steel 1.4028 420B?

The chemical composition of stainless steel 1.4028 420B is:

1.4028 420B steel chemical element % present
Carbon (C) 0.26 to 0.35%
Manganese (Mn) ≤ 1.50%
Silicon (Si) [Max] 1.00%
Chromium (Cr) 12.0 to 14.0%
Phosphorus (P) [Max] 0.040%
Sulphur (S) ≤ 0.030%
