Abstract
PURPOSE: To manufacture a fine-grain case-hardening steel causing no grain coarsening during carburizing by properly restricting the rolling conditions of a steel having a specified composition contg. C, Si, Mn, Cr, sol. Al and Nb and/or Ti.
CONSTITUTION: A steel consisting of 0.10W0.30% C, ≤0.50% Si, 0.30W1.80% Mn, 0.30W1.80% Cr, 0.005W0.060% Sol. Al, 0.01W0.10% Nb and/or Ti, and the balance Fe with inevitable impurities or further contg. 0.05W0.35% Mo is heated to the A3 pointW1,050°C and hot rolled at 850W1,000°C. By this method a case hardening steel having a normalized structure equal to that obtd. by normalizing and causing no grain coarsening during carburizing can be manufactured as hot rolled.
