2Cr13 Steel: A Versatile Martensitic Stainless Steel

2Cr13 is a martensitic stainless steel widely used in industrial applications. This grade of steel, containing approximately 13% chromium and 0.2% carbon, offers an excellent combination of corrosion resistance and mechanical properties.
2Cr13

Key Features:

  • Good corrosion resistance in mild environments
  • High strength and hardness after heat treatment
  • Excellent machinability
  • Moderate cost compared to higher-grade stainless steels

Common Applications:
The 2Cr13 steel bars find extensive use in:

  • Cutlery and kitchen utensils
  • Pump shafts
  • Valve components
  • Turbine blades
  • Surgical instruments
  • Industrial machinery parts

Heat Treatment:
To achieve optimal properties, 2Cr13 typically undergoes:

  1. Hardening at 980-1020°C
  2. Air or oil quenching
  3. Tempering at 200-300°C

Chemical Composition:

  • Carbon: 0.16-0.25%
  • Chromium: 12.0-14.0%
  • Silicon: ≤1.00%
  • Manganese: ≤1.00%
  • Phosphorus: ≤0.035%
  • Sulfur: ≤0.030%
