Stainless Steel - Grade 410 (UNS S41000)

Grade 410 stainless steels are general-purpose martensitic stainless steels containing 11.5% chromium, which provide good corrosion resistance properties. However, 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.

# Tempering of grade 410 steels should be avoided at temperatures of 425-600 °C, owing to associated low impact resistance.

Possible Alternative Grades

GradeReasons for choosing the grade

416

High machinability is required, and the lower corrosion resistance of 416 is acceptable.

420

A higher hardened strength or hardness than can be obtained from 410 is needed.

440C

A higher hardened strength or hardness than can be obtained even from 420 is needed.


Applications

Grade 410 stainless steels find applications in the following:

  • Bolts, screws, bushings and nuts

  • Petroleum fractionating structures

  • Shafts, pumps and valves

  • Mine ladder rungs

  • Gas turbines
