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.

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:
- Hardening at 980-1020°C
- Air or oil quenching
- 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%
