Stainless steel wire is well suited for harsh environments and can be used in ovens, industrial cleaning tanks and other industrial processes without additional coatings. It can withstand chemicals, salt water and other sources of corrosion for long periods of time.
Stainless steel wire is the raw material for screws, springs, metal mesh, cable wire and hardware. It is widely used in filtration, construction and critical electronic parts, petroleum and fiber industries, kitchenware and hardware.
