Advantages of stainless steel wire:

1. Highly resistant to rust and corrosion
2. High strength and robustness

3. Highly elastic and impact resistant to fire


Application Areas:
1. automotive industry: automotive suspension systems, braking systems and seat adjustment devices, etc., to provide stable elastic support and vibration damping effect, to enhance driving comfort and safety.
2. electronic products: used in keyboards, switches, buttons and other touch control components, to ensure that the frequent use of long time without losing performance.
3. Home furniture: widely used in mattresses, sofas, chairs and other furniture to provide comfortable support and elasticity.
4. medical instruments: used in surgical instruments, medical springs, etc., to ensure the stability and reliability of the product.
5. Power industry: not used in power switches, circuit breakers and other power equipment to ensure the normal operation and reliability of the equipment.


Quality Control
Raw Materials: MTC checking(PMI), Tensile strength test, Surface/Dimension inspection
Prodcution: Specially assigned person shall follow up and check according to the process flow card, and finally keep the copy
Before shipment: Mechanical properties test, Surface/Dimension inspection, or according to customers’ requirement


Quality control of raw materials
Slight changes in chemical composition and mechanical properties of raw materials will have a significant impact on the properties of finished steel wire. Therefore, the quality of base bar is one of the key factors to determine the quality of finished steel wire. We will strictly test the raw materials. Only raw materials that pass the test and meet the standards can go to the next process.


MTSCO can provide stainless steel and alloy steel spring wire with the diameter of 0.15-16mm, mainly grades are 300 series (301, 302, 304, 316, 321...) 130M, 200CU, 65Mn, 70#, 72A, 72B, 55SiCr, 50CrVA, etc. Our raw materials come from well-known steel mill in China, such as Yongxing, Baosteel,etc. Stainless steel spring wire has high corrosion resistance and good tensile strength. It is mainly used in spray springs, compression springs, tension springs, torsion springs, high-strength and high fatigue springs, medical springs, braided springs and other related fields.
