Product Overview
AISI 440C Martensitic Stainless Steel Round Bar High-carbon bright bar for extreme wear resistance
440C martensitic stainless steel (1.0% C, 16-18% Cr) delivers premium corrosion resistance with exceptional hardness. Ideal for bearing components in corrosive/non-lubricated oxidizing environments.
Key Characteristics
- Ultra-High Hardness: Achieves 58HRC post-heat treatment
- Temperature Stability: Maintains dimensional integrity at elevated temperatures
- Strength Limitations: Low dynamic load tolerance (prioritize static applications)
- Material Grades: Primary variants include 440A, 440B, 440C (optimal hardness), 440F (enhanced machinability)
Critical Applications
- Precision Cutting Tools: Surgical scalpels, industrial blades
- Bearing Systems: Corrosion-resistant bearings (utilizing temperature stability)
- Fluid Components: Wear-resistant nozzles & valves
- Critical Tooling: Specialty shears and razors
Core Applications
| Category | Specific Implementations |
|---|---|
| Cutlery | Chef knives, fillet blades, precision slicers |
| Industrial Tools | Cutting dies, processing blades, wear parts |
| Medical Instruments | Surgical scalpels, shears (hygienic + sharp edge) |
| Tactical Equipment | Combat knives, military blades (durability focused) |
Specialized Scope
- Bearing Systems:
- Corrosion-resistant bearings (non-lubricated/oxidizing atmospheres)
- High-temperature bearing steel (utilizing thermal dimensional stability)
- Precision Components:
- Nozzles, valve seats, wear-resistant mechanisms
- 440F Variant: Enhanced machinability for automatic lathe production
Critical Notes
Limited dynamic load capacity (optimized for static/stressed applications)
Delivery Condition: Supplied heat-treated unless otherwise specified
