Technical specifications
GOST 5632−2014 establishes the basic requirements for heat-resistant and relaxation-resistant steels. Let’s list the main ones. Ability to withstand certain mechanical loads (both static and dynamic) against a background of high temperatures, and with a certain type of loading; Corrosion resistance to corrosive gas atmospheres and water vapors in gaseous media at operating temperatures; Sufficient technological plasticity at realization of various technologies of plastic deformation, including at temperatures exceeding 600… 700 ° С — for deformable steels, and high indicators of fluidity — for steels obtained by casting.
