The standard of alloy spring steel wire (2)

Oil-tempered spring steel wire is the spring steel wire with the continuous heat and guide tempering after cold-drawn. Petrol quenching and tempering alloy spring steel wire is one of that steel wire, which also has several types, for instance Oil quenching ( blank ) tempering silicomanganese alloy spring steel wire and also oil quenched * tempered chrome silicon alloy spring steel wire useful for valve.

Listed here are standards of those two type spring steel wire: YB/T5104-93 and YB/T5105-93.

This spring manufactured by Oil quenching along with tempering alloy spring steel wire doesn't have quenching and tempering solutions. This planting season is nicely popular because it just would need to eliminate the tension like cold-drawing co2 spring steel wire. So the combination spring which usually diameter is actually <14.0mm tends to use these two standards more and more.

The YB/T5104-93 <Oil quenching - tempering silicomanganese alloy spring steel wire> is supplied of 3 categories. A category of spring steel wire is made for static spg of medium load, T class can be applied in the strong spring associated with medium heap and channel fatigue lifestyle, C category is for the particular dynamic spg used in great stress, for example car revocation springs. The regular deviation YB/T5105-93 <oil quenched - tempered chrome silicon alloy spring steel wire used for valve> is good for the powerplant valve arises under strong dynamic fill.
