Production and Application
Steel 10H17N13M3T (EI432) is a high alloy austenitic. Production is regulated by the following guests: 18, 143−72; 5632−72; 18, 907−73; 5949−75; 7350−77; 25, 054−81; 9940−81; 9941−81. This steel is used in welded structures, working in contact with acetic acid, phosphoric acids as well as in other environments increased aggressiveness. It is inert in 50% NaOH solutions up to 100 ° C, it is a basic material for the production of ethanolamines by hardware.

18 GOST 143−72, 5582−75, 5949−75, 7350−77 provide control 10H17N13MZT resistance steel to intergranular corrosion methods AM and AMU GOST 6032−89 after annealing at t ° to 650 ° C for 1 hour. This steel has a corrosion rate of 0.1 mm / year in 10% formic acid to 100 ° C; 50% citric acid at boiling tº; 5−25% H2S04 to 75 ° C; 50% acetic acid to 100 ° C and 80% to 80 ° C; 25% in boiling 40% H3P04 and H3P04 tº at 100 ° C. Mo reduces the resistance to intergranular corrosion in oxidizing environments, gives the steel type 17−13−2 (3) increased resistance to pitting corrosion in chloride-containing environments when compared to chromium-nickel marks such as 18−10.
The optimum temperature of hot deformation of 1200−850 ° C; for batches containing 5-ferrite deformation starting temperature is lowered. This steel allows for a high degree of cold deformation.
Well welded gas-electric, manual, automatic and electric welding. For manual arc welding is used VAW-13 electrodes, NIAT-1 and EA-400 / 10U; Automatic — wire Sv-06H19N10MZT and St-04H19N11 in conjunction with fluxes AN-26, 6-ANF and ANF-14.
