ASTM 410 Stainless Steel: Martensitic Grade for Hardness and Wear Resistance

Stainless Steel 410 is a type of stainless steel that is part of the martensitic steel. This category of stainless steel is characterized by its high hardness and strength, which comes from its high carbon content and the heat treatment processes it undergoes. Stainless Steel 410 contains a higher amount of chromium compared to other stainless steels, which provides it with good corrosion resistance.

 

Properties of Stainless Steel 410

1. SS 410 Chemical Composition

: 11.5% – 13.5%

: Up to 0.15% – 0.20%

: 1.0% max

: 1.0% max

: 0.75% max

: 0.04% max

: 0.03% max

2. Mechanical Properties

: 480 – 700 MPa

: 275 – 450 MPa

: 15 – 20% (in 50 mm)

: Can be hardened to 45 HRC (Rockwell Hardness Scale)

3. Corrosion Resistance

Stainless steel 410 has good corrosion resistance against atmospheric conditions and mild acids. It performs well in environments where it is exposed to air and water but can be prone to corrosion in more severe conditions.

4. Heat Treatment

SS 410 can be hardened by heat treatment to increase its hardness and strength. It can be heat treated at temperatures between 815℃ to 900℃ (1500℃F to 1650℃F), followed by quenching and tempering.

5. Magnetic Properties

Stainless Steel 410 is magnetic due to its martensitic structure, which differentiates it from austenitic stainless steels like 304 or 316, which are typically non-magnetic.
