Vacuum-degassed Steels from the Consumer's Viewpoint by A. F. Hoenie,J. Varga (Jr.),A. R. Elsea Pdf

Numerous industrial users were asked for their appraisal of vacuum-degassed steel. Their responses regarding the merits of this vacuum treatment were varied. The producers and users of large forgings reported fewer internal defects, improved toughness, and decreased processing time through shorter hydrogen relief treatments. Improved fatigue life in applications such as bearings was attributed to fewer and smaller nonmetallic inclusions in vacuum-degassed steel. The users of medium and small forgings reported only marginal improvement in properties and little or no change in rejection rates by nondestructive testing. Unfortunately, many of the users could not give a meaningful evaluation because they knew that frequently their suppliers filled orders with vacuum-degassed steels even though such treatment was not specified. Consequently, these users are unable to separate the air melted and the vacuum-degassed steels in their stock for comparison. A more comprehensive study of fully identified steels, steelmaking practice, degassing methods, material properties, and performance in service will be required before a satisfactory evaluation of the merits of vacuum-degassed steels can be made.

Vacuum Degassing in the Production of Premium-quality Steels by P. J. O'Reilly Pdf

This report gives the experiences of several steel producers and consumers with vacuum degassing as a melting practice in the manufacture of high-strength steels for critical applications. The parameters involved in determining the effects of melting practice on mechanical properties are outlined. Pertinent melting processes are described and evaluated qualitatively. In presenting the data, vacuum degassing is compared with other melting practices such as conventional air melting and consumable-electrode vacuum-arc remelting (CEVAR). Generally, there is a trend indicating that vacuum degassing is being used in some production applications instead of air-melted or CEVAR material. In terms of higher and more uniform transverse tensile properties and impact strength, longer fatigue life, and improved cleanliness, the CEVAR alloys were the best. Vacuum degassing by any of the various methods resulted in an improvement in properties of air-melted alloys. In some instances it appeared that the quality of CEVAR alloys could be approached when stream degassing or D-H (Dortmund-Horder) treatment was applied to air melts. Recommendations are given for additional investigations on the effects of melting practice on mechanical properties of premium-quality steels. (Author).
