Stainless Steel
What is Stainless Steel?
Stainless steels are a group of corrosion resistant steels that contain a minimum of 10.5 % chromium. There are other steels, including some tool steels that also contain these levels of chromium. The difference between these steels and stainless steels is that in stainless steels the chromium is added principally to develop corrosion resistance. The European standard for stainless steels, EN 10088 (published in the UK as BS EN 10088) defines stainless steels as steels with a minimum of 10.5% for use in applications where their corrosion resistance is required.
Many commercially available stainless steels contain more than this minimum level of chromium and, in addition, contain varying amounts of other alloying additions including nickel, molybdenum, titanium, niobium etc. These additions are made, not only to enhance the corrosion resistance of the steel but also develop other properties, such as mechanical strength, hardness, toughness, magnetic properties etc. or to change working characteristics including formability, machinability and weldability. Stainless steels can also be used in heat resisting and cryogenic applications as they also have excellent oxidation resistance. These particular steels generally have enhanced chromium levels to improve their heat resisting properties. They are covered by the BS EN 10095 standard.
The behaviour of the various stainless steels during manufacture, fabrication and in-service not only depends on their chemical compositions, but also on the design and surface finish of the manufactured items. Careful selection of the most appropriate steel grade, design and surface finish are vital to the successful application of stainless steels.
