Composition and properties
Steel grade 08X22H6T (EP53) is a stainless chromium-nickel alloy. It contains about 21-23% Cr, 6% Ni, 08% silicon and manganese, 0,4-0,6% titanium, 0,3% copper. Sulfur and phosphorus are contained in hundredths of a percent. Pipe made of this steel has a high resistance to corrosion and has a high tensile strength with fairly high ductility. It does not deform when heated in an oxygenated atmosphere or even pure oxygen and has no magnetic properties.

Application
Pipes made of this steel are used in the oil and chemical industry, in the manufacture of a variety of devices that come into contact with aggressive environments and must actively resist corrosion, for example, in shipbuilding. This alloy is used in the production of equipment for the pharmaceutical and food industries, for the manufacture of pumps that pump out mine water, as a material for decorative elements in architecture. The alloy can be included in the composition of bimetals, which are coated through a special gas spraying.
