The Stainless Steel Families

While the original form of stainless steel, (iron with around 12% Chromium) is still in widespread use, engineers now have a wide choice of different types (grades). In all, there are more than 100 different grades but these are usually sub-classified into distinct metallurgical "families" such as the austenitic, ferritic, martensitic and duplex families.

For more information on the different types of stainless steel, see Categories and grades.

The proportions of iron to chromium may be varied and other elements such as nickel, molybdenum, manganese and nitrogen may be added to widen the range of capabilities. Each particular grade of stainless steel has its own unique mechanical and physical properties and will usually be produced in accordance with an established national or international specification or standard.

For more information on the various national and international standards which define the various grades, see Standards.
