Thermal‐expansion, stress‐temperature, and thermal‐shock tests were conducted on glassed low‐alloy and plain‐carbon steels. The addition of alloying elements increases the hardenability and strength of the steels but lowers the austenite‐to‐ferrite transformation temperature, thus decreasing the residual compressive stress in the glass coating and therefore its resistance to thermal shock. It is shown that D 1 , the calculated hardenability index, may be correlated with certain physical properties of the glass‐steel composites.
