40X13 martensitic steel class consists mainly of iron and chromium. In accordance with GOST 5632−72, comprising 12−14% Cr and 0,35−0,44% carbon. The alloy is doped with elements such as Si, Mn, Ni — 0.6%, phosphorus thousandths of shares. Balance is iron. Smelted in an open electric arc, induction furnaces. Substitute: 30Ch13.
The percentage of the brand 40X13 (GOST 5632−72)
Steel heat-resistant, corrosion-resistant. Pipes are resistant to this class of soil and atmospheric moisture, slightly aggressive media, have a high tensile strength, ductility, but poorly welded. They are not subject to deformation under load at t ° to 450 ° C.

E — first-order modulus of elasticity [MPa]
a — coefficient of thermal expansion
Cold plastic deformation of the pipe is limited. The temperature of the hot deformation of 1100 — 900 ° C. The rapid heating and cooling of the material may crack. Therefore it recommended preheating pipes 850 ° C and slow cooling in the furnace. Tubes produce both round and the profile section… Long products, incl shaped made by the following guests: 2879−69, 2590−71, 2591−71, 5949−75.

The use of pipes
Construction, mechanical engineering, shipbuilding, manufacture of bearings, compressor parts and other products to working t ° 400−450 ° C in a slightly aggressive environments. Tubes are used to pump water miner efflux pumps and steam generators in the construction of power plants, in the production of salt by evaporation.
