GB/T 5267.4-2009
ActivePassivation of corrosion-resistant stainless-steel fasteners
紧固件表面处理 耐腐蚀不锈钢钝化处理
Application Summary AI generated
This standard specifies the passivation process for corrosion-resistant stainless-steel fasteners, such as bolts, screws, and nuts, to enhance their resistance to corrosion. It is applied in mechanical and industrial contexts where fasteners are exposed to harsh environments, including automotive, aerospace, and chemical processing equipment. The standard defines testing methods and acceptance criteria to ensure the passivation layer effectively prevents surface oxidation and maintains fastener integrity.
