Why does stainless steel rust?Because of the name stainless steel, many people believe that stainless steel does not rust. In fact, however, this is a very one-sided idea. Stainless steel also shows signs of rusting under certain conditions.
In Cr Ni austenitic stainless steel, the manganese content generally does not exceed 2%, and is mostly controlled at 1.5% in production. In the later development of nickel stainless steel, manganese becomes an important alloy element, which mainly forms stable austenite with nitrogen and a certain amount of nickel.
Carbon in austenitic stainless steel is an element that strongly stabilizes austenite and expands the austenite zone. The carbon gap is dissolved in austenite, and the strength of austenite can be significantly improved through solution strengthening.
Various industries report that some manufacturers have planned to cut production capacity due to the soaring cost of energy and raw materials. In the next year or two, European industrial manufacturing may not be able to meet the original demand.
