Stainless steel
Stainless steel is a steel which on the one hand is rustproof and on the other hand has a certain degree of purity. The stainless steel is corrosion resistant and from V4A saltwater resistant and acid resistant, which is why it is often used in certain areas, such as shipbuilding. Stainless steel has the properties that it is very durable, conductive, hygienic and temperature resistant. Stainless steel owes its durability to a very thin passive layer on the surface. Stainless steel can be unalloyed or alloyed steel. For a steel to be called stainless steel, it must have at least 10.5% cromium dissolved in the ferritic or austenitic solid solution. In addition, the sulfur and phosphorus content must not exceed 0.025%. The chromium content is decisive in preventing the steel from rusting. Stainless steel is comparatively more expensive than steel, due to the high alloy content. Some abbreviations of alloying elements: Cr = chromium Cu = copper Mo = Molybdenum N = nitrogen Nb = niobium Ni = Nickel Ti = Titanium Translated with www.DeepL.com/Translator (free version)
