Ferrite and austenite stainless steel

Chromium 15% to 30%. Its corrosion resistance, toughness and weldability with the increase of chromium content increased resistance to chloride stress corrosion better than other types of stainless steel, fall into this category are Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28 like. Ferritic stainless steel due to high chromium content, corrosion resistance and oxidation resistance are better, but the mechanical properties and process performance is poor, and more for large discontinuity as acid structure and antioxidant steel. Such steel resistant to corrosive atmosphere, nitric acid and saline solution, and has good high temperature oxidation resistance, thermal expansion coefficient, etc., for the nitric acid plant equipment and food, can also produce parts at high temperatures, such as gas turbine parts, etc.Stainless Steel Embossing Sheet
Chromium containing more than 18% of nickel also contains about 8% and a small amount of molybdenum, titanium, nitrogen and other elements. Good overall performance, corrosion resistant to many media. Austenitic stainless steel grades are commonly 1Cr18Ni9,0Cr19Ni9 like. Wc 0Cr19Ni9 steel 0.08%, steel marked "0." This kind of steel contains large amounts of Ni and Cr, the steel austenitic state at room temperature..brinell hardness of stainless steel
Such steel has good ductility, toughness and weldability, corrosion resistance and non-magnetic or weakly magnetic, corrosion resistance are good oxidizing and reducing media, the acid used to produce equipment such as containers and equipment corrosion liners, pipelines, nitric acid-resistant parts and other equipment, also can be used as the main material of stainless steel jewelry watches. Austenitic stainless steel commonly used solution treatment, the upcoming steel heated to 1050 ~ 1150 ℃, and then air-cooled or water-cooled, to obtain a single phase austenite.mild steel bar suppliers
