Question:

The anti-theft lock in the steel compression spring is what?

The anti-theft lock in the steel compression spring is what?

Answer:

The development trend of suspension spring steel is to reduce carbon content, reduce decarburization tendency, and increase the flexibility and anti attenuation performance of plastic forming.
Spiral spring requires surface decarburization less than 0.5% of the diameter, polished surface, long fatigue life, dimensional tolerances more stringent requirements, there should be no defect transmission. The hot working process is often difficult to meet the requirement of the user, therefore, hot forming of cold forming of automotive suspension coil spring gradually replaced by drawing, heat treatment (quenching and tempering of martensite GET) spiral spring made after.
The use of stainless steel spring wire suspension spring wire is advanced, high strength, long fatigue life, the effect is good damping characteristics, spring steel wire, the number and distribution of inclusions, so the chemical, high surface quality, decarbonization, microstructure and mechanical performance requirements.
