Abstract
Inventia se refera la un otel cu proprietati superioare de rezistenta si tenacitate, într-un domeniu de temperaturi cuarins între -50 si 450 degree C. Otelul are o compozitie chimica bine determinata, nu este aliat cu elemente deficitare (Cr, Mo, Ni, Ti, V etc.si numai prin elaborare, prelucrare si tratament termic, se realizeaza continuturi scazute de S, P, H2, N2, O2 incluziuni nemetalice s.a. Turnarea otelului se efectueaza la temperaturi cuprinse într-un ecart optim si restrâns. Pentru prelucrarea prin deformare plastica la cald, s-a determinat coroiajul minim necesar realizarii unor caracteristici mecanice ridicate. Otelul, conform inventiei, poate fi utilizat la fabricarea de echipamente pentru centrale nuclearo-electrice, recipinete sub presiune, constructii metalice s.a.
