Product Description

About products

Alloy spring steel is a kind of steel that can improve the mechanical properties, hardenability and other properties of steel by adding one or several alloy elements on the basis of carbon steel to meet the requirements for manufacturing various springs. The basic composition series of alloy spring steel include silicon manganese spring steel, silicon chromium spring steel, chromium manganese spring steel, chromium vanadium spring steel, tungsten chromium vanadium spring steel, etc. On the basis of these series, some brands add alloy elements such as molybdenum, vanadium or boron to improve their performance in some aspects.
