Oil quenching and tempering spring steel spring wire quenching the quenching medium is used when the oil, rather than the commonly used water medium.
Spring wire is used to make a spring (SPRING) or wire type (WIRE FORM) of a wire. According to the different purposes of the spring, the springs are required to do spring steel wire are many types, such as the lower requirements of mattress spring spring wire (referred to as mattress steel wire), making shock absorber spring wire, spring hanging spring Steel wire, spring steel wire for engine valve and spring wire for camera shutter, etc. Although there is no uniform standard classification name, the quality requirements of these steel wires are different. Spring wire can also be classified according to the manufacturing process, such as raw spring wire (before drawing without lead-quenching), lead quenched spring steel wire, galvanized spring steel wire, oil quenched spring steel wire.
Quenching oil: animal oil (such as lard), vegetable oil (such as rapeseed oil, salad oil), mineral oil (oil), semi-synthetic oil (mineral oil and synthetic oil, is a variety of special quenching oil), synthetic oil Synthetic, various grades of special quenching oil).
