316 Stainless Steel
Also known as marine-grade stainless steel, 316 is similar in machinability and weldability to 304, but has far superior corrosion resistance. It has far higher yield strength than both 303 and 304, meaning that it will not bend as easily. This material is hardened by cold work.
