Most fasteners are made of carbon steel or alloy steel and generally require corrosion resistance. Therefore, surface coatings must adhere firmly to prevent peeling during installation and removal. For threaded fasteners, coatings must also be sufficiently thin to ensure threads can engage properly ......
View DetailsQuenching cracks are common quenching defects caused by internal stresses that cannot be released during the quenching process. Preventing crack formation should begin at the product design stage. This involves selecting appropriate materials, implementing rational structural design, specifying suit......
