| Stainless steelsStainless steels play an important role in many fields:
Daily life, the engineering, food processing and chemical industries, transport, medicine, surgery, etc.
These are steels, alloys of iron and carbon, to which essentially chrome is added which, above 12 to 13%, produces the desired resistance to oxidation.
Other elements can be added, notably nickel, which improve its mechanical properties in general and ductility in particular, and other elements such as molybdenum or titanium which improve alloy stability for temperatures other than ambient temperature as well as elements with a high melting point such as vanadium and tungsten usually accompanied by an increase in chrome content to obtain resistance to high temperatures in contact with flames (heat-resisting steels).
To be classified in the stainless category, a steel must contain at least 11% chrome.
The most current ones are as follows:
X2CrNi18-10 (304L): C: 0.02%, Cr: 17 to 19%, Ni: 9 to 11%, used for all quality work.
X2CrNiMo17-12 (316L): C: 0.02%, Cr: 16-18 %, Ni: 11-13 %, Mo (molybdenum): 2%, used in the chemical, pharmaceutical, oil and food processing industries, … as well as a great deal in the maritime environment.
X8Cr17 (430): C: 0.08 %, Cr: 16-18%, used for household items, domestic appliances, sinks.
X6CrTi12 (409): C: 0.06 %, Cr: 11-13%, Ti (titanium), used in car exhausts, furnaces etc.
Most of the stainless steels used comply with standards (chemical analysis in% by weight):
European (standard EN 10088 in particular).
American (AISI standards); L means low carbon, H means High carbon.
Other countries also have standards but they are little known internationally.
Product certificate on demand.
