Abstract
PURPOSE: To improve the yield ratio and temper softening resistance of boron steel by combinedly adding Cu and V to the Mn-Cr-B medium-carbon steel.
CONSTITUTION: This born steel with a high yield ratio and high temper softening resistance has a composition consisting of 0.3W0.5% C, ≤1.0% Si, 0.5W2% Mn, ≤1.5% Cr, 0.1W0.5% Cu, 0.0005W0.005% B, 0.1W0.3% V, 0.005W0.05% Ti, ≤0.06% Al and the balance Fe with impurities or further contg. 0.05W0.2% Nb. This boron steel is superior to an Mn-Cr-Mo medium-carbon steel of the same kind in yield ratio and temper softening ratio.
