304 stainless steel spring wire

Type 304 stainless steel spring wire, also known as "18/8" stainless steel, is the most widely used austenitic stainless steel due to its reliable corrosion resistance and mechanical strength. It contains approximately 18% chromium and 8% nickel, delivering excellent durability for various applications.
