302 Stainless Steel Spring Wire
We supply premium 302 stainless steel spring wire with wire diameters ranging from 0.1mm to 6.0mm, with a combined monthly output of 6,000 tons for carbon and stainless steel wire. Precise cold drawing process delivers stable tensile strength and excellent formability for every 302 stainless steel spring wire.
Core Material Performance
Outstanding elasticity
Multi-pass cold drawing treatment endows the wire with stable elastic modulus for reliable spring rebound performance.
High tensile strength
Tensile strength reaches 1600MPa ~ 2300MPa depending on wire diameter and hardness state to meet diverse load demands.
Reliable anti-corrosion property
Chromium and nickel alloy composition delivers stable resistance against atmospheric and water corrosion.
Superior formability
Good plastic deformation performance allows easy coiling into torsion, compression and extension springs of all shapes.
Hardness & Surface States
Multiple hardness grades available: light drawn, half hard, full hard, selectable per customer's coiling process and performance standards. Two surface finishes: bright finish and matte finish to satisfy different appearance requirements.
Application Scope
Suitable for manufacturing all types of springs, hardware fasteners and wire mesh, widely adopted in hardware, electronics and mechanical manufacturing industries.
Independent Wire Production Capacity
Baoding Zhongxin Spring Manufacturing Co., Ltd. operates self-owned wire production lines with total monthly output of 6,000 tons for carbon and stainless steel wire. Self-produced carbon steel wire directly feeds our spring workshop to control raw material quality from the source, while we also sell various spring wires to external clients. For stainless steel wire such as 302 stainless steel spring wire, we maintain long-term stable cooperation with major steel mills to guarantee consistent raw material supply and uniform quality. Self-production cuts intermediate costs, enabling us to offer competitive pricing for both finished springs and raw spring wire materials.
