Composition and Properties
Steel brand 14H17N2 (EI268) is complexly stainless chromium-nickel alloy martensitoferritnogo class. It is composed of 16−18% chromium, 1.5−2.5% nickel, 0.8% manganese and silicon, 0.3% copper and 0.2 of titanium, 0,11−0,17% of carbon and thousandths of a percent of phosphorus and sulfur. Specific weight rolled at 20 ° C 7,75 g / cm³. Pipes of this alloy grades have exceptional resistance to corrosion, the highest rate of tensile strength, ductility and sufficient processability.

Quality and Use of pipes
Made of alloy pipes are widely demanded in various spheres of human activity. They are heat-resistant, does not undergo deformation at high temperature in an environment rich in oxygen does not have strong magnetic properties. Pipes from a steel successfully resist rust, widely used in shipbuilding, chemical, petroleum, food, medical industry. They are released at a price that is slightly higher than the average cost of stainless steel, however, the reliability and durability of products to justify all costs. Steel 14H17N2 successfully used as a structural material for the production of discs, shafts, bushings, pumps and compressors operating in hostile environments. Pipes in demand in the construction of steam generators in power plants, as well as the production of salt.
