本标准概述了提高钢氢脆风险的条件，并定义了将氢脆风险降至最低所需的缓解程序。其目的是控制过程。由于在清洗、磷化和电镀过程中吸收氢，钢的氢脆会在应力下导致脆性断裂。氢脆敏感性随着应力（内部或外部施加应力）的增加和材料强度的增加而增加。本规范中的硬度读数采用维氏硬度计。应参考SAE J417以转换为其他标尺。

This standard outlines the conditions that enhance the risk of hydrogen embrittlement of steel and defines the relief procedures required to minimize the risk of hydrogen embrittlement. It is intended to control the process.Hydrogen embrittlement of steel, which can cause brittle fractures under stress, occurs as a result of the absorption of hydrogen during cleaning, phosphate coating and plating processes. The susceptibility to hydrogen embrittlement increases with increasing stress (internal or externally applied stress) and increasing material strength.Hardness readings in this specification are in Vickers scale. SAE J417 should be referred to for conversion to other scales.
