1: 440C Steel Introduction
The main characteristics of 440C mold steel include excellent corrosion resistance, high hardness, and good wear resistance. 440C mold steel also has good processing performance and can achieve ideal hardness and wear resistance through heat treatment processes such as quenching and tempering. It can also be processed through conventional machining methods such as cutting, milling, and grinding, and is suitable for mold manufacturing of various shapes and sizes. 440C mold steel has become the preferred material for many high-end mold and tool manufacturing due to its excellent corrosion resistance, high hardness, and good wear resistance.
