Music Wire – Per ASTM-A228 or AMS 5112. Music wire springs are not recommended for applications where the temperature exceeds 121 deg. C
Stainless Steel Type 302 – ASTM-A313 or AMS 5688 spring tempered (chemical & physical only). Stainless steel springs are not recommended for applications where the temperature exceeds 260 deg. C .
Type 302 stainless steel is slightly magnetic. Surface of stainless steel may have a residue of nickel on the surface. This is normal and will not affect the function of the part.
Direction of Helix – Right Hand
Standard finish is that of the normal wire. Shot-peened and plated finishes furnished on request. Allow sufficient additional time for special finishes.

According to customer requirements
|0. 5-1. 5||2-22||<250|
|Hot roll forming||10-16||30-250||<800|
|Note: In addition to the above specifications, if the customer has special requirements, the company can design and manufacture.|
|product material||Carbon spring steel, alloy spring steel, stainless spring steel, copper alloy, nickel alloy, etc.|
|Material selection and allowable stress||1. For important springs, when the damage has a significant impact on the entire machine, the allowable stress is appropriately reduced;|
|2. The spring treated with high pressure can increase the fatigue limit and have obvious effect on the relaxation under load.|
|The allowable stress can be properly increased;|
|3. The shot peening spring can also improve the fatigue strength or fatigue life, and its allowable stress can be increased by 20%;|
|4. When the operating temperature exceeds 60 t , the shear modulus should be corrected.|
|main application||Railways/Automobiles/Electronics/Electrical Machinery/Industrial and Mining|
