Surgical stainless steel of body piercing jewellery and body modification implants. 440 and 420 stainless steels, known also by the name "Cutlery Stainless Steel", are high carbon steels alloyed with chromium. They have very good corrosion resistance compared to other cutlery steels, but their corrosion resistance is inferior to 316 stainless. Biomedical cutting instruments are often made from 440 or 420 stainless due to its high hardness coupled with acceptable corrosion resistance. This type of stainless steel may be slightly magnetic. Surgical stainless steel Surgical stainless steel is a grade of stainless steel used in biomedical applications. The most common "surgical steels" are
Stainless steel fiber Stainless steel fiber Stainless steel fibers are manufactured fibers composed of stainless steel. Composition may include carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), and other elements. Currently stainless steel fibers are manufactured primarily in Europe. The most common uses for stainless steel fibers is in the field of the electrical and textiles industry such as anti-radiation cloth, thermal resistant fabric, and anti-static brushes. Many people also use stainless steel fibers in weaving. Increasingly common today are stainless steel fibers in clothing, including radiation protection for pregnant women. Stainless steel yarns are woven, braided, and knit into many
