Inorganic Surface Coatings – Post-Coating Heat Treatment of Iron or Steel to Reduce Hydrogen Embrittlement. ISO 9588:2007 specifies guidelines for heat treatment of iron and steel components after applying metallic surface coatings to reduce the risk of hydrogen embrittlement. Hydrogen embrittlement occurs when hydrogen infiltrates the metal during the coating process, causing the material to become brittle and prone to cracking under stress. The standard describes how proper heat treatment can remove or reduce hydrogen, thereby enhancing the component’s durability and performance. It specifies parameters such as temperature, time, and atmosphere during heat treatment to achieve optimal results. This standard is particularly important for applications where metallic components are subjected to high stress, such as in the automotive and aerospace industries.
