Stamping Spring Steel Retainer Black oxidized stamping clips

Spring is used under impact, vibration or long-term crossstress, so spring steel is required to have high tensile strength, elastic limit, high fatigue strength. In the process, spring steel is required to have a certain degree of hardenability, not easy to decarbonize, good surface quality and other carbon spring steel, namely, high quality carbon structural steel with carbon WC in the range of 0.6%-0.9%. Alloy spring steels are mainly silicon-manganese steels, which have slightly lower carbon content, and their properties are improved mainly by increasing silicon content Wsi. In addition, there are chromium, tungsten, vanadium alloy spring steel.
