Marc Glasser on The Tools and Trade Secrets of Heat Resistant Alloy Welding

Heat resistant alloys used for heat treating fixtures, muffles, retorts, radiant tubes, and other parts are typically stainless steel or nickel based austenitic alloys. Metallurgists are often asked many questions on the proper welding methods. Austenitic stainless steels require rapid cooling to prevent solidification cracks due to hot cracking. Thus different procedures are required.

In this Heat Treat Today feature, Marc Glasser, Director of Metallurgical Services for Rolled Alloys, provides some basic information on metallurgy as well as good welding practices to follow.
