Spring steel wire is one kind of steel wire used for spring or wire form. According to the different application area of spring, the quality requirement of spring steel wire has a very big difference. We make various spring steel wires for mattress, bumper, suspension spring, engine valve, camera shutter and so on. The steel spring wire can also be classified into 4 main types based on manufacturing technology: galvanized spring s teel wire, patented spring steel wire, oil tempered steel wire and general type wire.
The raw materials for spring steel wire include 65#,70#,65Mn, 82B,72A,72B steel wire rod.
Spring Wire use of materials for:65# 70#, 65Mn,82B,72A,72B wires, is characterized by low plasticity, flexibility strong, powerful anti-stress.
