Description / Abstract:


This report was prepared in response to a request from the Working Panel on Metals, Subgroup P on Materials, of The Technical Cooperation Program, and covers the metallurgical characteristics and mechanical properties of the HY-80, HY-100, and HY- 130 steels and weldments made from these steels as presented in the open literature and in reports on Government-sponsored research. The emphasis is placed on base-metal weldability and mechanical properties of weldments. This report combined with DMIC Report 229(1) provides a comprehensive study of the weldability of steels ranging in yield strength from 80,000 psi to over 300,000 psi.

The principal advantages of the HY materials are their good combination of strength and toughness and their good weldability in heavy thicknesses with little preheat and no postweld heat treatment. The good weldability was designed into these materials during their development, and suitable filler metals and welding procedures were developed concurrently. These materials are presently being used by the U. S. Navy for submersible.s and have industrial applications in pressure vessels.

The objectives of this report are to summarize the properties and weldability of HY-80, HY-100, and HY-130 steels, to review recent developments in welding each of these materials, and to point out major areas for future study.
