What is Stainless Steel?

Stainless steel usually containing 10 to 30 percent chromium. In conjunction with low carbon content, chromium imparts remarkable resistance to heat and corrosion. Other elements, such as aluminum, sulfur, copper, nitrogen, molybdenum, titanium, niobium, phosphorus, or selenium, may be added to increase corrosion resistance to specific environments, enhance oxidation resistance, and impart special characteristics. It was a generic name for these steels and now covers a wide range of steel types and grades for corrosion or oxidation resistant applications.

The grade most often used is Grade 304 (1.4301) for corrosion resistant reinforcement, suitable for most atmospheric and concrete covered environments.

TheGrade 316 (1.4401) has a higher molybdenum and nickel content than 304 (1.4301). It is more expensive but also has higher corrosion resistance and is the recommended grade for marine and corrosive environments.
