410 (UNS S41000) Stainless Steel

General Properties

Alloy 410 is the basic, general purpose martensitic stainless steel that is used for highly stressed parts and provides good corrosion resistance plus high strength and hardness. Alloy 410 contains a minimum of 11.5% chromium which is just sufficient enough to demonstrate corrosion resistance properties in mild atmospheres, steam, and many mild chemical environments. It is a general purpose grade that is often supplied in the hardened but still machineable condition for applications where high strength and moderate heat and corrosion resistance are required. Alloy 410 displays maximum corrosion resistance when it’s been hardened, tempered, and then polished.


Specifications: UNS S41000


Applications:

Applications requiring moderate corrosion resistance and high mechanical properties are ideal for Alloy 410. Examples of applications that frequently used Alloy 410 include:

  • Cutlery

  • Steam and gas turbine blades

  • Kitchen utensils

  • Bolts, nuts, screws

  • Pump and valve parts and shafts

  • Mine ladder rugs

  • Dental and surgical instruments

  • Nozzles

  • Hardened steel balls and seats for oil well pumps


Standards:

  • ASTM/ASME: UNS S41000

  • EURONORM: FeMi35Cr20Cu4Mo2

  • DIN: 2.4660


Corrosion Resistance:

  • Good corrosion resistance to atmospheric corrosion, potable water, and to mildly corrosive environments

  • Its exposure to everyday activities (sports, food preparation) is generally satisfactory when proper cleaning is performed after exposure to use

  • Good corrosion resistance to low concentrations of mild organic and mineral acids


Welding Characteristics

  • Readily welded by all standard methods

  • To reduce the risk of cracking, it is suggested to pre-heat the work piece to 350 to 400oF (177 to 204oC)

  • Post weld annealing is recommended to retain maximum ductility


Heat Treatment

  • The proper hot work range is 2000 to 2200oF (1093 to 1204oC)

  • Do not work this material below 1650oF (899oC)
