Alloy grade 03KhN28MDT (EP516)) is used in the manufacture of welded equipment for the production of any concentration of sulfuric acid, phosphoric acid extraction, nitrophos production, as well as other compounds with high aggressiveness. The main difference between 03XHN28MDT and 06XHN28MDT is that the former has a higher resistance against intergranular corrosion of welded joints andAlloy 03CrN28MDT produced according to 1) TU 14-1-756-73; 2)

The temperature range of 06CrNi28MdT hot deformation for forging, forging and rolling is 1170-900°C. The alloy is satisfactorily machined by cutting. Alloy 03CrN28MdT is satisfactorily welded by electric arc, argon arc manual and automatic welding. As an additive material is always used wire Sv-01HN28MDT during manual arc welding electrodes OZL-17U, during automatic arc welding - flux AH-18.
