Abstract
PURPOSE: To provide an unrefined high tensile steel with enhanced toughness and tensile strength in the weld bond zone and superior weldability by specifying the amt. of C, Si, Mn, Cr, V, Ti, Al, N, etc. to be added to a low C-Mn-Cr steel.
CONSTITUTION: A steel consisting of C; 0.01W0,09%, Si; 0.1W0.8%, Mn; 1.1W 2.5%, V; 0.02W2.1%, Ti; 0.005W0.05%, Al; 0.001W0.1%, N; 0.002W0.015%, and the balance iron and impurities, or further contg. Ni≤2.5% or B; 0.0005W 0.005% if necessary. The addn. of a limited amt. of V esp. features this steel. V is easily dissolved in austenite unlike Nb, and a change in hardness due to cooling rate is decreased. Although this steel has a tensile strength above 60 kg/mm2, it can be welded without being preheated, and toughness in the weld heat-affected zone is enhanced.
