Performance:
- Hardness: After heat treatment, the hardness of 3Cr13 can reach approximately 50-55 HRC, making it suitable for applications that require good wear resistance.
- Corrosion Resistance: Compared to non-stainless steels, it offers better corrosion resistance, but its corrosion resistance is lower than that of austenitic stainless steels (such as 304 and 316).
- Toughness: It has good toughness, making it suitable for applications that require impact resistance.
Applications:
3Cr13 steel is commonly used in:
- Cutting Tools: Such as knives, scissors, and other hand tools, due to its good edge retention.
- Medical Instruments: In situations where corrosion resistance and hardness are required.
- Valves and Pumps: In the chemical processing industry.
- Other Components: Such as molds and dies, where a combination of strength and corrosion resistance is essential.
Heat Treatment:
3Cr13 can be heat treated to enhance its hardness and mechanical properties. The typical processes include quenching and tempering.
Comparison:
Compared to other stainless steels, such as 420J2 and S420, 3Cr13 is often used in applications that require higher hardness, while 420J2 may offer better performance in environments with lower corrosion resistance.
