Abstract (en)
[origin: EP0709481A1] The low alloy steel comprises (wt.%): 0.24-0.35 C; 1-2.5 Mn; 0.3-2.5 Cr; 0.2-1.6 W; 0.1-0.8 (Mo+W/2); 0-25 Ni; 0-0.3 V; 0-0.5 Si; 0.002-0.005 B; 0.005-0.1 Al; 0-0.1 Ti; 0-0.02 P; and 0-2 Cu. There may also be present less than 0.1% of at least one of the following: Nb, Zr, S, Se, Te, Bi, Ca, Sb, Pb, In and rare earth elements. The remainder is Fe plus possible impurities. The compsn. also satisfies the following equations: U = 409(%C) + 19.3(%Cr + %Mo + %W/2) + %V) + 29.4(%Si) + 10(%Mn) + 7.2(%Ni) < 200 and R = 3.82(%C) + 9.79(%Si) + 3.34(%Mn) + 11.94(%P) + 2.39(%Ni) + 1.43(%Cr) + 1.43(%Mo + W/2) < 11.14.
