Stainless Steel Composition Percentage
The composition of stainless steel is usually around 10-20% chromium, with the rest made up of various other metals such as nickel, molybdenum, titanium and copper. Exact composition percentages vary depending on the grade and type of stainless steel. For example, austenitic stainless steels typically contain 16-26% chromium, while ferritic and martensitic stainless steels typically contain 14-22% chromium. The addition of small amounts of other metals can also have a major impact on the overall properties of steel. For example, adding molybdenum increases corrosion resistance, while adding titanium increases strength.
