化学成分分析

主要合金元素决定了这款钢在耐磨、耐蚀与韧性之间的基本走向。

材质综述

CPM 420C is a stainless steel produced using Crucible’s Particle Metallurgy process, improving the carbide distribution and overall performance compared to conventional 420-series steels. It delivers a balanced combination of toughness, corrosion resistance, and wear resistance while remaining relatively easy to sharpen. The steel is especially valued in applications where durability and rust resistance are more important than extreme edge retention.
