Method of Production and Properties of Blanks of Bodies of Chromium Steel 10Kh9MFB Pipe Fittings for Thermal Power Plants

摘要

In chromium steel pipelines it is necessary to use fittings made also from chromium steel to ensure uniform physicomechanical properties; however, such fittings are not produced in Russia and are completely imported. The results of developing a technology of manufacturing and investigating the bodies of D_N 250 - 300 fittings made from chromium steel 10Kh9MFB by the electroslag melting method are given.
