14H17N2 Wire, circle
Chrome-nickel steel 14H17N2 (EI268) is an alloy of stainless steel complexly martensitoferritnogo class. Specific weight rolled at 20 ° C 7,75 g / cm³. The high quality of this steel can use it in harsh industrial environments. In its composition of 16−18% chromium and 1.5−2.5% nickel, 0.8% manganese and silicon, 0.3% copper and 0.2% of titanium, carbon — 0,11−0,17%, thousandths of a percent of phosphorus and sulfur. Chromium and nickel, to protect the surface structures from corrosion and wet corrosion cracking impart resistance to intergranular corrosion. Additives silicon, manganese, titanium further improves manufacturability and performance.

Bars, wires and the circle of 14H17N2 alloy has exceptional corrosion resistance and strength, in this case — the high ductility and workability. The wire is manufactured according TSMTU 664−41 bars — in accordance with GOST 1525−53. Bars, wire and round steel 14H17N2 stable in contact with corrosive and neutral salts, alkalis, fresh and sea water, so used in the installation parts for the production of salt.
Bars, wire and terms of the alloy used for the production of a variety of technical details in the various fields. Such heat-resistant parts, they are not subjected to deformation at high temperature in an environment rich in oxygen does not have strong magnetic properties successfully resist rust. They are used in chemical, petroleum, food and medical industry. Products brand 14H17N2 released at a price that is slightly higher than the average cost of stainless steel, however, the reliability and durability of the material justifies all costs. Steel 14H17N2 successfully used for the production of fasteners, flanges, shafts discs, bushings, pumps and compressors, operating in aggressive environments and as part of bimetal, which are applied to the surface by spraying a special gasometric.
