SUS 302 Spring Tempered Stainless Steel Wire With Soap Coated / Bright Surface
stainless steel spring wire SUS 302 Soap coated/Bright 0.25 - 18mm
Stainless steel is extremely versatile and is selected for its use primarily due to its corrosion and heat resistant properties.
This makes it the ideal material for springs operating in low maintenance environments or where replacement is difficult.
Coatings
To ensure maximum performance and efficiency when machining, our spring wire is supplied with a consistent soap coating that enables the spring forming machines to run efficiently at high speeds with excellent spring coiling characteristics.
For certain applications where no soap coating is required we also offer a bright finish.
As a leading manufacturer of stainless steel, we have been working with many big companies in Europe and Asian.We are in a good position not only to supply you high quality stainless steel wire, but also the excellent sales service. Well-trained engineers and sales will offer you any technical support.
