Austenitic Stainless Steel

- Sep 29, 2017 -

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