Production and Application
Mark 08X18H10T (EI914) is made according to the following guests: 5632−72; 18 907−73, 4405−75, 5582−75, 5949−75; 25, 054−81; 9940−81.Takaya steel is chrome-nickel alloy austenitic. Smelted in electric arc furnaces. It has increased resistance to intergranular corrosion in industrial environments, compared with alloys and 12X18H10T 12X18H12T. Its use in the manufacture of welded structures operating in highly aggressive environments at t ° -196 to + 600 ° C without pressure control.

In accordance with GOST 5582−72, 7350−77 and 4986−79, such steel in testing methods and AM AMU GOST 6032−89 resists intergranular corrosion control solutions when exposed 8 and 24 hours. These tests are conducted after annealing (1 hour) at t ° 650 ° C.
Steel 08X18H10T on the technological parameters of the same brand 12X18H9T (10T). From them it is different better resistance welds to intergranular corrosion and knife in a chemical production.

The σ — limit of short-term strength;
σ T — yield limit for residual deformation;
δ 5 — elongation at break.
With automatic submerged arc welding uses the same filler materials, as for 12X18H9T alloys (10T).
