Some improved methods have been established recently in Japan with reference to manufacturing of cast alloy steel rolls, built-up and back-up rolls, main steam pipes for, high temperature and high pressure boilers and heat resistant high alloys for gas turbines. The purpose of the present paper is to describe the engineering technique for manufacture of these products of alloy steels covering importnt processes from melting to inspection.
