Stainless Steel Type 304 is the most widely used variety stainless steel. It is a slightly magnetic, highly corrosive-resistant material with a lustrous metallic finish. Its consistent wire surface quality, relatively high strength and great corrosion resistance make it attractive for many applications. The wire can be drawn bare or with a black oxide surface. Stainless Steel Type 304 conforms to ASTM A313 and is available in a wide variety of wire gauges and weave sizes.
