Spring Temper Wire
We produce versatile spring temper wire with grades 65Mn, 70#, 82B and 60Si2Mn, wire diameter ranging from 0.5mm to 10mm. Complete stress relief tempering eliminates internal residual stress to guarantee stable dimensional accuracy of finished springs made from spring temper wire.
Outstanding User-Friendly Advantages
No secondary heat treatment required
Pre-tempered state allows direct coiling and assembly, saving manufacturers' heat treatment equipment investment and processing time.
Stable elastic output
Uniform tempering delivers consistent spring stiffness and even rebound force across finished products.
Superior forming ductility
Low breakage rate during coiling and bending, improving production yield.
Low post-forming deformation
Residual internal stress is removed in advance, so finished springs maintain fixed size without warping.
Surface & Mechanical Performance
Surface options include bright finish and oxide finish. Tensile strength ranges from 1300MPa to 2000MPa according to material grade and wire diameter, with steady and reliable mechanical indicators.
Application Scope
Suitable for general industrial springs, hardware fittings, stationery springs and toy elastic parts with moderate performance requirements.
User-Oriented Optimized Material Design
Baoding Zhongxin Spring Manufacturing Co., Ltd. develops materials fully considering downstream clients' production efficiency, and spring temper wire is designed to reduce customers' processing burdens. Clients can start coiling immediately after receiving the wire without extra heating procedures, cutting production costs and lowering defective rates. Besides temper wire, we supply various wire states and specifications to match different production processes and product standards, offering the most convenient raw material solutions for spring manufacturers.
