The most commonly used stainless steel alloy of this type is Grade 304 stainless steel, which is one of the most versatile alloys on the market. Grade 304 is an austenitic chromium alloy, which is also known as an "18/8" stainless steel since it contains 18% chromium and 8% nickel. As a result of its high chromium content, the material offers considerable resistance to corrosion and oxidation. While stainless steel alloys are resistant to most oxidising acids and can withstand ordinary rusting, they may tarnish over time. In order to increase the steel's tensile strength, it must be cold worked. Post-weld annealing may be required for stainless steel sections that are heavily welded.
