410 Stainless Steel

410 stainless steel is suitable for applications where high strength and moderate heat and corrosion resistance are required.

Type 410 is a martensitic alloy commonly supplied in the hardened but still machinable condition.  Type 410 has excellent hardness after heat treatment and the material can be used in the fabrication of highly stressed parts.

Applications include valves, gar turbines, parts for pumps, heating control shafts and kitchen utensils.  We supply 410 in sheets, strips, bar, wire and forging billets, contact us today for the best prices.

410 Stainless Steel

  • 410 Stainless Steel is a martensitic stainless steel that provides good corrosion resistance plus high strength and hardness

  • Type 410 has fair machinability.
  • It has somewhat better machining characteristics than austenitic stainless steels, having a rating of about 55% compared to Bessemer screw stock (AISI B 1112).
  • Sulfurized cutting oils are used for most operations.


  • Type 410 has reasonably good cold working properties and can be moderately drawn and formed.
  • Severe working should be done hot with bars at 1350-1500° F.

410 Stainless Steel Heat Treatment

  • ANNEALING: Heat slowly to 1550-1650° F cool to 1100° F in furnace, air cool.
  • PROCESS ANNEALING: Heat to 1350-1450° F, air cool.
  • HARDENING: Heat to 1700-1800° F, oil quench. Follow by stress-relief or temper.
  • TEMPERING: Heat to 1100-1400°F for 1 to 4 hours, air cool.


  • Type 410 can be readily forged at 2300° F.
  • Preheat steel to 1800° F for 2 hours, raise rapidly to 2300° F, soak for 4 to 6 hours, forge, slow cool.

Corrosion Resistance

  • Type 410 provides a good corrosion resistance to air, water and some chemicals.
  • Its resistance to nitric acid, concentrated sulfuric acid, dilute acetic acid and naphtha is satisfactory.
  • It also provides good resistance to food acids.


  • Type 410 has good weldability.
  • It is readily joined by fusion and resistance welding methods.
  • Type 410 filler rod should be used for weldments that will be annealed or hardened and tempered after welding.
  • Type 309 or 310 filler rod should be used to obtain maximum weld metal ductility in the as-welded condition.
  • Ductility of fusion welds can be improved by annealing at 1450-1500° F and slow cooling.
