Abstract
Inventia se refera la un otel de scule, otelul având un continut redus de elemente de aliere. Otelul are compozitia chimica formata, în procente de greutate, din 1,35% la 1,45% C, 0,40% la 0,55% Mn, 1,00% la 1,70% Si, 1,30% la 1,70 % Cr, 0,40 la 0,80 % W, 0,75% la 1,25% Ti, max. 0,30% V, max. 0,30% S, max. 0,03% P, max. 0,20% Cu. Tratamentul termic al otelului respectiv consta dintr-o încalzire la temperatura de 870...890 degree C, racire în ulei, cu revenire la 180 degree C.
