上海隆进出售316LUJ钢板#低铁镍尿素钢
Austenitic stainless steel: 316 luj all at room temperature with austenitic stainless steel of the organization. Contains about 18% of Cr, Ni in steel of 13% ~ 15% and about 0.03% C, has the stable austenite rust including famous high chromium-nickel steel and on this basis, increase content of Cr, Ni and Mo, Cu, Si, N, P and other elements of high Cr - Ni series steel. All austenitic stainless steel nonmagnetic and has high toughness and plasticity, but strength is low, can't by phase transformation strengthening, can only be strengthened by cold working. If add other elements such as, good free cutting. Such steel in addition to the acid medium corrosion resistance to oxidation, if it contains the elements such as Mo, Cu has ability of sulfuric acid, phosphoric acid, formic acid, acetic acid and urea corrosion. If carbon content less than 0.03% of such steel can significantly improve the intergranular corrosion and corrosion resistance. High silicon austenitic stainless steel of concentrated nitric acid have good corrosion resistance. Because the austenitic stainless steel has comprehensive and good comprehensive performance, in walks
