08H22N6T alloy pipe
Composition and Properties
Steel brand 08H22N6T (EP53) is a nickel-chromium stainless steel alloy. It consists of about 21−23% Cr, 6% Ni, 08 at% of silicon and manganese, 0.4−0.6% titanium, 0.3% copper. Sulphur and phosphorus are in hundredths of a percent. of the steel pipe it has high corrosion resistance and has increased strength at a sufficiently high ductility. It is not deformed by heating in an oxygen rich atmosphere, or even pure oxygen has no magnetic properties.
The percentage of 08H22N6T grade (GOST 5632−72)
Due to its high resistance to most of the concentrated alkali, hydrofluoric acid, a saturated salt sea water, such an alloy is widely demanded in various fields. It is not recommended to use air, enriched solutions of acids and acidic medium at a temperature above 375 ° C,

σ T — yield limit for residual deformation.
Pipes of the steel used in the petroleum and chemical industry, in the production of a variety of devices that come into contact with aggressive media and must actively resist corrosion, for example, in shipbuilding. This alloy is used in the manufacture of equipment for the pharmaceutical and food industry, for the manufacture of pumps, bilge water from mining, as a material for decorative elements in architecture. The alloy may be included in the bimetal, which are applied to the coating through a special spraying gasometrical.
