AISI 410

Quick Facts

Type 410 is a martensitic stainless Steel that provides good corrosion resistance plus high strength and hardness. It is magnetic in both the annealed and hardened conditions. A wide range of properties can be
developed with different heat treatments.

Typical Applications

  • Springs,
  • knives, bolts, screws, nuts and bushings
  • tools,
  • Gas turbines,
  • Shafts, pumps and valves,

Applications require moderate corrosion resistance and high mechanical properties are ideal for this Alloy.

Mechanical Properties

Typical annealed properties

AISI 410


Grade 410 steels can be easily machined in highly tempered or annealed conditions. However, it is hard to machine grade 410 steels if they are hardened above 30HRC. Free machining grade 416 is the best alternative.

Material Conditions

This Alloy can be supplied in annealed and quenched and tempered condition.

Corrosion Resistance

Grade 410 stainless steels are resistant to hot gases, steam, food, mild acids and alkalies, fresh water and dry air. These steels obtain maximum corrosion and heat resistance through hardening. However, grade 410 steels are less corrosion resistant than austenitic grades and grade 430 ferritic alloys containing 17% chromium. Smooth surface finish offers improved performance of steels.

Heat Treatment

Annealing – Grade 410 steels – can be fully annealed at temperatures from 815 to 900°C, followed by slow furnace cooling and air-cooling. Process annealing of grade 410 steels can be carried out at temperatures ranging from 650 to 760°C and air-cooled.
Hardening – Hardening of grade 410 steels can be performed at 925 to 1010°C, followed by air and oil quenching. Heavy sections of grade 410 need to be oil quenched. Tempering, to enhance the mechanical properties and hardness of grade 410 steels, follows this process. It is not recommended to perform tempering at temperatures from 400 to 580°C.
