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

420C sits at the top of the 420 stainless steel family in terms of carbon content, giving it improved hardness and edge retention compared to 420A and 420J2. It remains a budget-friendly stainless steel, widely used in entry-level to mid-range knives. While it cannot compete with modern powder metallurgy steels, it provides a practical balance of corrosion resistance, ease of sharpening, and acceptable cutting performance for everyday tasks.
