Austenitic stainless steel

Sep 30, 2016

Containing more than 18% chromium, also contains about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Comprehensive performance, can be resistant to a variety of media corrosion. Austenitic stainless steel commonly used brands have 1Cr18Ni9, 0Cr19Ni9 and so on. 0Cr19Ni9 steel Wc <0.08%, steel in the marked "0". This type of steel contains a lot of Ni and Cr, so that steel at room temperature was austenite. This type of steel has good plasticity, toughness, weldability, corrosion resistance and non-magnetic or weak magnetic, oxidation and reducing medium corrosion resistance are good, used to make acid-resistant equipment, such as corrosion-resistant containers and equipment Lining, pipeline, nitric acid-resistant equipment parts, etc., can also be used as the main material of stainless steel watch jewelry. Austenitic stainless steel is generally used solution treatment, the steel is heated to 1050 ~ 1150 ℃, and then water-cooled or air-cooled, in order to obtain single-phase austenite.
