Ningbo Huayuan Metal manufacturers high quality stainless steel spring wire from 0.30 to 16.0mm in bright and soap coated surface finish. We registered “Topone” as our Trade Mark. Topone stainless spring wire can be supplied in 1/2 hard, 3/4 hard and full hard conditions, which are all manufactured as per ASTM A 313, JIS G4314, EN 10270-3 and other equivalent international standards.

Application
Topone stainless steel spring wires are widely used for producing various types of spring like compression spring, extension spring, torsion spring, and other special shaped spring as well. Its sound quality guarantees excellent yield rate in coiling even by robot, satisfys various customer needs from precision spring , high strength spring to medical use spring. Some large consumptions of Topone stainless spring wire in daily chemicals are aerosol spring, sprinkler in irrigation,lock and faucet in hardware, lighting industrial as well as some in automobile, aerospace, medical, electronic and office supply, etc.

Quality
Topone stainless spring steel wire win its market for its sound quality with good price. Because Ningbo Huayuan Metal has controlled the tensile strength of wire during and after all processes of manufacturing and before delivery It ensures the wire tensile strength to meet our customer specific needs. We even care about the weather that may have effects on wire drawing tensile and adjust our machine condition and change wire drawing process to fit the changing weather. And we buy better raw material from biggest and best Chinese stainless steel rod manufactures with control on specific chemical compositions. We are using drawing lubricants from Germay Brand Traxit as well as Adeka from Japan(There is no hazardous coating or lubricant used). And wire drawing tools are always kept in good condition all day as we have 20+ years skilled tool technician to take care of them. These are five reasons that Topone stainless steel spring wire quality is comparable to some of top brands’ stainless steel spring wire. If you want to try it, just contact us to get wire sample for a test.
