Round Steel Spring Bar 60Si2MnA

Product Description:

Spring Steel can be divided into two types. One is carbon spring steel, and other one is alloy spring steel.

Alloy spring steel is based on carbon spring steel, by adding one or more alloying elements to improve the mechanical properties, hardenability and other properties to meet the requirement for manufacturing all kinds of spring steel.
