Abstract
PURPOSE: To provide the nonrefined tough steel having a sufficient strength and toughness for use as machine structure material by particularly incorporating much amount of N and each specific amount of one or more of C, Si, Mn, Ti, V, and Nb.
CONSTITUTION: The nonrefined tough steel consists of C: 0.3W0.8%, Si: 0.5W 1.5%, Mn: 0.5W2%, Ti: 0.01W0.05%, N: 0.29TiW0.025%, and one or >2 kinds of V: 0.01W0.1%, and Nb: 0.01W0.1%, and the residual% Fe and impurities. The amount of N in the steel should at least correspond to Ti of deposited TiN, i,e, more than 0.29%. The nonrefined tough steel allows only the process of hot rolling, hor forging, or normalizing, without refining, to provide both strength and toughness comparable to ones provided by conventional refined tough steel.
