Grade 410 (1.4006) is a hardenable martensitic stainless steel available in bar form only.
410 stainless steel is a martensitic stainless steel known for its high strength, moderate corrosion resistance, and good wear resistance. It is part of the 400 series of stainless steels and is widely used in applications that require strength, hardness, and moderate corrosion protection.
The corrosion resistance of grade 410 steels can be further enhanced by a series of processes such as hardening, tempering and polishing. Quenching and tempering can harden grade 410 steels. They are generally used for applications involving mild corrosion, heat resistance and high strength.
Martensitic stainless steels are fabricated using techniques that require final heat treatment. These grades are less resistant to corrosion when compared to that of austenitic grades. Their operating temperatures are often affected by their loss of strength at high temperatures, due to over-tempering and loss of ductility at sub-zero temperatures.
