GB/T 19349-2003
AbolishedMetallic and other inorganic coatings--Pretreatment of iron or steel to reduce the risk of hydrogen embrittlement
金属和其他无机覆盖层 为减少氢脆危险的钢铁预处理
Application Summary AI generated
This standard specifies pretreatment processes for iron or steel components to minimize the risk of hydrogen embrittlement before applying metallic or inorganic coatings. It is applied in manufacturing industries, particularly for high-strength steel parts such as fasteners, springs, and automotive components that undergo electroplating or chemical surface treatments. The standard is used in quality control and production environments to define cleaning, stress relief, and baking procedures that reduce hydrogen absorption during surface preparation.
