Product introduction:

Spring wire is a kind of steel wire used to manufacture spring or wire form.

Product classification:

According to different spring purpose, there are different types of spring wire. such as:Spring wire for mattress spring, spring wire for shock absorber, spring wire for suspension spring, spring wire for engine valve spring, spring wire for camera shutter and so on.

Spring wire can be classified according to the manufacturing process. such as: without lead bath quenching processing spring wire, the lead quenching spring wire, galvanized spring wire, oil quenching spring wire and so on.

According to variety, standards and specifications of different tensile strength, the strength of the spring wire grade is in 1000-3 billion ranges. Circular spring wire diameter range is between 0.08-20 mm. The cross section shape of spring wire is usually circular, rectangular, square, oval shape; Steel wire is commonly deliveried rolls by rolls and also deliveried in straight. 

Others: Stainless steel spring wire; Round steel rod spring steel wire; Steel fiber spring steel wire; Bending spring wire; Coil spring wire; Super hard spring wire; and so on.

Product manufacture and material selection:

Different types of spring steel wire have different production methods and the common characteristic is certain strength, high toughness and good performance of coil spring. Spring material selection principle is: first of all, meet the functional requirements; the second is to meet strength requirement, the last to consider economy.  Carbon spring steel is widely used in the spring steel. Alloy spring steel contains 0.45% ~ 0.70% of carbon and a certain amount of Si, Mn, Cr, V, W and B and other alloying elements. 

Application:

Manufacture spring or wire form.
