Product Description
440C Stainless Steel Raw Material Overview
440C Stainless Steel is the highest-carbon martensitic stainless steel (1.0-1.1% C) with exceptional hardness, wear resistance, and edge retention. Containing 16-18% chromium, it achieves Rockwell hardness up to 60 HRC after heat treatment, making it the ultimate choice for high-end cutting tools, bearings, and precision components.
Key Physical Properties
| Property | Annealed Condition | Heat-Treated Condition |
