What kind of steel wire should be used for valve spring?
JIS Marine valve Manufacturer shares that the quality of the valve spring determines whether the valve works properly or not, so this material is a crucial choice, in case of wrong selection, it is a failure. What material should they use? Today, the valve manufacturer will tell you which material to choose.
Generally our common valve spring material is stainless steel spring steel wire, high temperature spring alloy wire, oil quenching and tempering alloy spring steel wire. Stainless steel spring steel wire production DIN valve spring manufacturers prefer. Because stainless steel spring steel wire should have excellent comprehensive performance, such as mechanical performance (especially elastic limit, strength limit, bending strength ratio), anti-elastic reduce performance (namely anti-elastic decline performance, also known as anti-relaxation performance), fatigue performance, hardenability, physical and chemical performance (heat resistance, resistance to low, oxidation resistance, corrosion resistance, etc.). In order to meet the above requirements, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization), accurate shape and size.
Only high quality stainless steel spring steel wire used for JIS marine globe valve, can ensure the valve spring good high temperature resistance, life, stability, corrosion resistance and other requirements.
