X12Cr13, 1.4006, AISI 410 - Description and purpose

Stainless corrosion resistant chromium martensitic steel used for the production of steam turbine blades, bolts, hydraulic press valves, cracking apparatus, water pump parts, nuts, stainless steel sieves for coal screening and other components working in contact with water and steam.

It exhibits very good resistance to adipic, arsenic, benzoic, boric, maleic, gallic, and malic acid, or at low temperatures or concentrations to: nitric, chromic, gallotannic, carbolic, barium, aluminum, and potassium acids, and ammonium hydroxide. It is not resistant to salts and sulfur compounds.

1H13 steel is delivered softened and heat-treated. It does not exhibit significant strength properties compared to conventional structural steels due to its relatively low carbon content, but unlike steels with a higher carbon content, it is more resistant to corrosion.


Mechanical properties

  • Tensile strength Rm = 650 - 850 MPa
  • Yield point Re: >450 MPa
  • Elongation A > 15%
  • Modulus of elasticity E = 215 GPa
  • Thermal conductivity coefficient λ = 30 W ⋅ m-1 ⋅ K-1
  • Thermal capacity cp = 460 J ⋅ kg-1 ⋅ K-1
  • Hardness in softened state 121 - 187 HB

Heat treatment 1H13 - processes, cooling and temperatures

  • Softening annealing in the 750 - 800 ℃ temperature range with cooling in a furnace
  • Hardening at 950 - 1050℃ with oil or air cooling
  • Tempering at 700 - 790℃ with water, oil, or air cooling

Steel properties at elevated temperatures

  • Coefficient of linear expansion α
    • for a temperature of 100 ℃ = 10,5 ⋅ 10-6
    • for a temperature of 200 ℃ = 11,0 ⋅ 10-6
    • for a temperature of 300 ℃ = 11,5 ⋅ 10-6
    • For a temperature of 400 ℃ = 12,0 ⋅ 10-6
  • Modulus of elasticity E
    • for a temperature of 100 ℃ = 215 GPa
    • for a temperature of 200 ℃ = 205 GPa
    • for a temperature of 300 ℃ = 200 GPa
    • for a temperature of 400 ℃ = 190 GPa
  • Yield point Re
    • for a temperature of 100℃ > 420 MPa
    • for a temperature of 200℃ > 400 MPa
    • for a temperature of 300℃ > 365 MPa
    • for a temperature of 400℃ > 305 MPa
