08KH22N6T - эп53 Pipe
Composition and properties
Steel brand 08KH22N6T (ЭП53) is a chromium-Nickel stainless steel alloy. In its composition approximately 21−23% Cr, 6% Ni, 08% silicon and manganese of 0.4−0.6% titanium, 0.3% of copper. Sulphur and phosphorus are contained in hundredths of a percent. Pipe made from this steel is highly resistant to corrosion, has higher tensile strength at a sufficiently high plasticity. It does not deform when heated in an oxygenated atmosphere or even pure oxygen has magnetic properties.

σT is the yield stress for permanent deformation.
Pipe from this steel is used in the petroleum and chemical industries, in the manufacture of various devices that come into contact with aggressive environment and should actively to resist corrosion, for example, in shipbuilding. This alloy is used in the production of equipment for pharmaceutical and food industries, for the manufacture of pumps, pumping of mine water as a material for decorative elements in architecture. The alloy can be included in the composition of the bimetals which are applied to the coating by means of a special gasometrical spraying.
