Book Description
This report represents the compilation of papers on the problems in the load-carrying application of high-strength steels. The papers were presented in five sessions at a symposium sponsored by the Tripartite Technical Cooperation Program on October 26-28, 1964, in Washington, D.C. Session I consists of papers on the broad subject of high-strength steels, to reflect the present state of the art, and on potential applications for these steels, including the design-material interplay. Session II papers deal with production and fabrication, with emphasis on the effects on, and the subsequent properties of, the resulting fabricated products. Session III papers deal with the very critical topic of corrosion sensitivity of high-strength steels, protection against corrosion, and the effects of protection techniques on steel behavior. The papers in Session IV are devoted to mechanical behavior characteristics of design significance. The papers of the last session deal with high strength steels by technical types so as to obtain an integrated picture of their behavior, properties and processing techniques; the papers also discuss strengthening mechanisms per se.

Welding High-strength Steels
Author: P. A. KammerPublisher:
ISBN:
Category : Martensitic stainless steel
Languages : en
Pages : 68
Book Description
Recent studies of the developments in welding steels with yield strengths greater than 150 ksi have included low-alloy martensitic steels, medium-alloy martensitic steels, nickel maraging steels, and bainitic steels. Only weldments from medium-alloy martensitic steels and nickel maraging steels have mechanical properties approaching those of the base plate without a complete postweld heat treatment. The most serious problem with the other steel is low toughness in the weld fusion zone. Adequate weld metal toughness under conditions of elastic strain can be obtarined over the entire 150 to 225 ksi yield-strength range only if the tungsten-arc welding process is used. Processes with higher deposition rates can produce comparable weld deposits only in the lower portion of the range. Above a yield strength of 200 ksi, 18Ni maraging steel weldments have the best combination of strength and toughness. Below 200 ksi, the HP 9-4-25 medium-alloy martensitic steel and 12Ni maraging steel weldments have nearly equal properties.

Book Description
This report resulted from a survey of users and manufacturers of maraging steels, Government agencies, research institutions, and published literature. It presents the technical status of the 18-percent nickel maraging steels in detail and brings together a large body of knowledge with regard to the metallurgical and engineering aspects of maraging steels. Since such steels were first announced in 1959, they have become highly important in aerospace, defense, and industrial work. The requirements of the National Aeronautics and Space Administration have given impetus to their development, and research now underway is expected to result in further improvements and applicability. The NASA Office of Technology Utilization sponsored this report as part of its program to disseminate information on technological developments which appear to be useful for general industrial applications.
New Developments in Welding Steels with Yield Strengths Greater Than 150,000 PSI
Author: Robert Melvin EvansPublisher:
ISBN:
Category : Steel
Languages : en
Pages : 18
Book Description
The report summarizes the advancements made in the development and welding of steels possessing yield strengths greater than 150,000 psi. Steels discussed include the medium carbon, low-alloy martensitic steels; low carbon alloy martensites; and nickel maraging steels. Almost all programs which have the objective of developing high-strength steels have an equally important phase concerned with filler metal development. Filler metals are also discussed. The new welding processes discussed are Narrow-Gap welding, electron-beam welding, plasma-arc welding, high-frequency resistance welding, electroslag welding, laser welding, and interrupted-arc (dip trasfer) MIG welding.

Pages : 48
Book Description
This report is the third of a series which will periodically summarize the status of the various contracts involved in the Department of Defense Refractory Metals Sheet Rolling Program. Under this program, selected candidate materials are being carried through one or more of the following consecutive phases: Phase I, development of a sheet-production practice; Phase II, establishment of minimum design data; and Phase III, evaluation of sheetfabrication characteristics. To the present time, 13 contracts have been funded or planned in support of the Phase I, II, and III activities. This report summarizes the status of each of these individual contracts as of November 1, 1964. The first section describes the overall program of the Department of Defense Refractory Metals Sheet Rolling Program. Following, in the order of their discussions, are sections dealing with fabricable molybdenum alloys, unalloyed tungsten, columbium alloys, and tantalum alloys. (Author).
