WELCOME TO CSW Spring Wire Co., Ltd.
Since its foundation in 1998, CSW Spring Wire Corporation has cooperated with many companies both at home and abroad, most of which have been our regular customers. It is fully proven that our high quality products and considerable service win their trust.
Our company have been focus on manufacturing various spring wires which can be fabricated as compression spring, tension spring, torsion spring and other special springs. For corrosive working environments, T316 stainless steel spring wire, Nickel-coated and galvanized music wire are available in round or flat shapes. As to your special requirements, our professional engineers can make custom spring wires.
Type 302 stainless steel is an austenitic alloy of 18 percent chromium and 8 percent nickel. Due to these two added elements, T302 stainless steel spring wire is the most popular stainless steel in manufacturing springs because of its excellent corrosion resistance as well as high tensile strength and toughness at cryogenic temperatures. Meets with ASTM-A-313 and AMS-5688. Diameters of spring wire range from 0.001" to 0.625".
Unlike T302 stainless steel, T316 possesses a slightly higher nickel content and extra molybdenum, both of which provides better corrosion resistance. Compared with T302, however, T316 has a lower tensile strength and is slightly less magnetic. Excellent cold working properties makes it superior to cold working conditions, while outstanding creep strength allows for good performance under elevated temperatures. Meets with ASTM A 313. Wire diameters comes in 0.009 to 0.5 inch.
Zinc-coated music spring wire possesses high corrosion resistance ability. Uniform zinc coating is applied to the wire prior to the final drawing operation, producing a hard surface suitable for automatic spring coiling and mechanical forming without cracking or peeling. Meets with ASTM-A-228. It has high carbon content which provides high tensile strength and hardness. Galvanized music wire are available for springs of tension, compression and torsion.
Inconel spring wire processes an outstanding combination of high strength, hot and cold workability and resistance to ordinary form of corrosion. It also exhibits good heat resistance and aging or steer corrosion through tough work conditions. The high chromium content of alloy 600 considerably resist oxidation while high nickel content offers excellent corrosion resistance under reducing conditions.
Cold drawn inconel 600 spring wire embraces good mechanical properties as well as workability. Diameters range from 0.057in. to 0.563in. Premium corrosion resistances allows for working in tough environments. Available in coil springs, wire springs, compression springs, torsion springs, barrel springs, die springs and so on.
Which spring wire should I choose?
We can' t give your answer at once. For the spring wire will finally affect the quality of spring. Please kindly advise your application, working environment, and mechanical property of the spring, then our skilled personnel can provide you the right answer.
Our quality control guarantees quality
Quality control is designed to build a solid relationship with both our vendors and customers. We deeply know that the real success relies on our ability to decrease production cost and at the same time satisfying every aspect of our customers' requirements.
We require all our suppliers who provide us raw material of spring wire to conform to the terms of our purchase requirements. All our staff holds one point that only continually performance to our standards in quality gives us reputation as well as profit.
T316 Stainless Steel Wire
T316 stainless steel spring wire has a little higher content of nickel which provides better corrosive resistance than T302.
T302 Stainless Steel Spring Wire
T302 stainless steel spring wire is widely most in springs for its excellent resistance to corrosion and oxidation.
Inconel 600 Spring Wire
Inconel 600 spring wire processes excellent combination of mechanical properties, cold workability and resistances to common corrosion.
Nickel-coated Music Wire
Music spring wire with nickel-coating provides outstanding drawing features of consistency and reliability. Conforms to ASTM-A-228 and SAE-J-178.
