Type 410 stainless is a martensitic alloy commonly supplied in the hardened but still machinable condition.

Excellent Hardness

The alloy contains 11.5% chromium which provides good resistance to atmospheric corrosion. However, corrosion resistance is limited unless the alloy is further enhanced by processes including hardening, tempering and polishing. Type 410 displays excellent hardness after heat-treatment and the material finds use in the fabrication of highly stressed parts. Weldability of the alloy is generally poor.

Benefits

Type 410 stainless steel is a commonly used martensitic stainless steel grade. Once heat treated, the alloy has excellent hardness properties and is suitable for use in stressed parts. Note that Type 410 has limited corrosion resistance and weldability is generally poor. The alloy finds use in commercial applications such as petrochemical.
