Product Description

INTRODUCTION
Our stainless steel spring wire has the following characteristics:
1.excellent straightness with good helix and cast for automatic coiling.
2.uniform & beautiful surface condition.
3.excellent coil-forming ability.
4.high elasticity and high fatigue resistance.
5.strong heat resistance against exposure to the toughest atmosphere.
6.wide usage for electronic/electrical appliance, whatever it is nonmagnetic or slightly magnetic.
SURFACE CONDITION
Our stainless steel spring wires are distinguished by their surface status, which are bare wire, ni coating and resin coating. They can also be divided into bright surface, dull surface and semi-bright surface. The customer can make choice according to exact requirements.
MECHANICAL PROPERTY
Generally we produce stainless steel spring wire in accordance with the specifications of JIS WPB, JIS WPA, WPC & ASTM. Products of special specifications are available when customers require.

PRODUCT GRADE
We can supply several kinds of stainless steel spring wire with the following chemical compositions:

Type 302/304 are most popularly used in the manufacture of springs because of their outstanding mechanical property and corrosion resistance. Type 316 is recommended for the manufacture of springs which require a particularly high corrosion resistance and non-magnetic property, but it's mechanical properties are somewhat inferior to those of type 302/304, type 631J1/631 are used for heat resistanet spring and the finished spring has the highest strength among all stainless steel alloys after heat treatment, but poorer corrosion resistance than type 302/304
