摘要

Steel casting producers make small heats of specialty alloys for custom products. Unlike bulk producers like steel mills, casting producers frequently make non-standard alloys in small quantities, which requires them to be able to formulate heat compositions and heat-treat cycles for non-standard alloys. To develop the methodology for estimating the tensile properties from a non-standard composition, a new database of standard steel cast alloys with composition and tensile properties was used. Standard specifications for steel castings require a tensile test to qualify heats. These tensile properties were collected for common steel casting alloys. This SFSA data set has over 30,000 entries. There are numerous formulas used to estimate hardness, hardenability, etc. The data set and an analysis of reported formulas to estimate properties like ideal diameter, carbon equivalent, or estimated hardness in heat treatments or welds have been evaluated for their ability to predict properties for non-standard alloy heats.
