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
  1. Bearing Systems:
    • Corrosion-resistant bearings (non-lubricated/oxidizing atmospheres)
    • High-temperature bearing steel (utilizing thermal dimensional stability)
  2. 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
