60si2mna Oil Tempered Spring Steel Wire

The content of 60Si2MnA alloy is low, the hardenability is higher than 60Si2Mn, the ductile plasticity is high, the decarbonization tendency is small, the tempering stability is good, the heat processing performance is good, the cost is low.60 si2mna is widespread in the Shanghai area in north China adopting the grain steel sales chemical concentration of the hardness testing and metallographic examination method, the article 60 si2gra play a sudden break in the production process are analyzed.In place of 60Si2MnA, it makes heavy, medium and small car springs and other mid-sized section springs and spiral springs.The yield strength of the foreign language name 60Si2MnA is greater than 1225(125) (MPa).
