Composition and properties
Steel grade 14X17H2 (EI268) is a complex alloyed stainless chrome-nickel alloy of martensitic-ferritic class. It consists of 16-18% chromium, 1.5-2.5% nickel, 0.8% manganese and silicon, 0.3% copper and 0.2 titanium, carbon 0.11-0.17% and thousands of percent of phosphorus and sulfur. The specific gravity of the rolled steel at 20 °C is 7.75 g/cm³. Alloy tubes of this grade have exceptional resistance to corrosion, the highest tensile strength, sufficient ductility and manufacturability.

Tube qualities and usage
Tubes made of the alloy are widely in demand in a wide variety of human activities. They are heat-resistant, are not subject to deformation at high temperatures in an oxygen-rich environment, do not have pronounced magnetic properties. Pipes made of such steel successfully resist the formation of rust and are actively used in shipbuilding, chemical, oil, food and medical industries. They are sold at a price that is slightly higher than the average cost of stainless steel, but the reliability and durability of products justify all costs. Steel 14Cr17N2 is successfully used as a structural material for the production of disks, shafts, bushings, pumps and compressors working in corrosive environments. Pipes are in demand in the construction of steam generators in power plants, as well as the production of salt.
