Effects of Composition and Gage on the Microstructure of A533-B Steels

Source

The effects of composition and gage on the microstructure of quenched and tempered A533-B steel were studied. The tests were performed on experimental heats of varying carbon contents. To fully assess the effects of minor variations in composition, the carbon equivalent was calculated and used in the data analysis. Controlled cooling was used to approximate gage effects, and the makeup of microstructure was studied by lineal analysis. Equations were generated from the experimental data to predict the microstructure as a function of carbon equivalent and cooling rate. These predictions are verified by comparing them with the microstructures of commercial heats.
