1. Carbon spring steel:
The carbon content (mass fraction) of carbon spring steel is generally {{0}}.62 percent 0.90 percent . According to its manganese content, it is divided into general manganese content (mass fraction) (0.50 percent 0.80 percent ) such as 65, 70, 85 and higher manganese content (mass fraction) (0.901.20 percent ), such as 65Mn.
2. Alloy spring steel:
Alloy spring steel is based on carbon steel, by appropriately adding one or several alloying elements to improve the mechanical properties, hardenability and other properties of the steel to meet the properties required for the manufacture of various springs.
Summarize:
This is classified according to the chemical composition of automobile shock absorbers, which are mainly made of high-strength steel.
