“All Metals & Forge carries two types of Nitralloy: Nitralloy 135 and Nitralloy 135m. Nitralloys are a group of metals that were specifically designed for a hardening process called "nitriding." This process creates a high surface hardness and a strong resistance to corrosion, without the risk of distortion that other hardening processes can create.” ) g1 x9 w) C2 c4 S# fNitralloy 意思为经过渗氮处理的特定设计的一组金属材料，135-G or 135Modified是两种不同的类型
