440C stainless steel round bar to ASTM A276 is a high-carbon martensitic stainless steel known for its extreme hardness and wear resistance.
What Is 440C Stainless Steel?
440C is designed for applications where:
- High hardness is required
- Wear resistance is critical
- Components operate under load
It can be heat treated to very high hardness levels compared to other stainless grades.
Why ASTM A276 Matters
ASTM A276 covers stainless steel bar used in:
- Precision machining
- Grinding applications
- Tight tolerance components
It ensures consistency in:
- Chemistry
- Mechanical properties
- Dimensional quality
Key Benefits of 440C
- Extremely high hardness after heat treatment
- Excellent wear resistance
- Good corrosion resistance for a hardened grade
- Ideal for precision ground applications
440C vs Other Stainless Grades
Common Applications of 440C ASTM A276
- Bearings
- Valve components
- Pump parts
- Cutting tools
- Precision shafts
When to Use 440C
Use 440C when:
- Wear resistance is critical
- High hardness is required
- Parts operate under friction or load
Avoid when:
- High machinability is needed
- Toughness is more important than hardness
