Abstract

PURPOSE: To provide a low alloy steel for high strength bolts obtd. by adding a specified amt. of C, Si, Mn, S, Cr, sol. Al and B to iron, the various characteristics of which such as strength, reduction of area, hardness, etc. have been improved by tempering without requiring annealing before cold forging.
