Stainless steel wire is under the action of drawing force will wire or wire blank from the die hole of the drawing die, to produce a small section of steel wire processing process.The wire with different section shapes and sizes can be produced by drawing. The size of the wire is accurate and the surface is smooth. The drawing equipment and mould used are simple and the cost is low.In general, the greater the cross-sectional area ratio before and after drawing, the greater the tensile strength and hardness of the steel wire. The implementation standard of stainless steel wire is: GB/T4240 2009,According to the soft and hard state of the steel wire, it can be divided into:

Stainless steel soft wire(S), commonly known as the hydrogen annealing silk, its made by large hydrogen annealing equipment, via pickling and annealing at temperature around 1050°C, to reduce the hardness, improve the plasticity, eliminate internal stress, refine and remove tissue inhomogeneity, grain organization more even, the surface quality is more exquisite, light, soft, non-magnetic, anti-fatigue, extension strength, etc. Specification range: 0.05~16mm, tensile strength is 600~800MPa, the hardness states "1/8h" or "1/4 h".

Stainless steel lighty drawing wire(LD),the base material after the heat treatment to cold drawi to reduce the section, it is soft, fatigue, has a certain extension force and other characteristics, it commonly used as cold pier materials. Specification range: 0. 3~ 16mm, tensile strength is around 800~1100MPa, the hardness states "1/2H".

Stainless steel cold drwaning wire(WCD),The Stainless steel wire is routinely drawn after heat treatment good toughness, wear resistance. Specification range: 0.1 ~12mm, tensile strength is around 1100~1500MPa, hardness states "3/4H".

Stainless steel spring wire, the use of its unique standard: GB/ T24588-2009, marking its unique status, spring wire hardness high, strong elasticity, wear-resistant compressive performance, but poor toughness, relatively easy to break. Stainless steel spring wire can be distinguished by the surface for bright spring wire and fog surface spring wire, fog surface spring wire is after cold drawing through chemical passivation, so the price is slightly higher than bright spring wire, but its wear-resisting compressive performance and toughness is same as stainless steel bright spring wire. Specification range: 0. 05~10mm, tensile strength greater than 1500MPa, hardness from low to high divided into "H" and" SH".
