Die steel grade 16MnCr5 case hardening steel characteristics

16MnCr5 steel is a low-alloy steel suitable for mold manufacturing, and its performance can be significantly improved through surface hardening. Firstly, in the heat treatment stage, methods such as carburizing or nitriding are used to infiltrate carbon or nitrogen into the steel surface to form a hard layer, thereby increasing hardness and wear resistance. Secondly, the quenching process makes the surface structure brittle while maintaining toughness internally through rapid cooling, improving strength and wear resistance. Finally, tempering treatment is used to eliminate brittleness caused by quenching, balance hardness and strength, and ensure overall stability.

After these treatment methods, 16MnCr5 steel has high hardness, excellent wear resistance, and strength after surface hardening, making it very suitable for use in mold applications that require high wear resistance and strength. This special treatment enables the mold to maintain its shape accuracy and surface quality during long-term use, extending the mold's lifespan and improving production efficiency. Therefore, the surface hardening characteristics of 16MnCr5 steel make it an ideal material choice, suitable for various mold manufacturing fields such as injection molds, die-casting molds, and stamping molds.
