After proper heat treatment, it can obtain higher yield strength and hardness can reach 58HRC, which is among the hardest stainless steel. The most common application example is the "razor blade." There are three commonly used models: 440A, 440B, 440C, and 440F...
*Austenitic grades X55CrMnNiN20-8 to X33CrNiMnN23-8 may show hardness values which cannot be converted into tensile strength values acording to the standard tables commonly used in laboratories. Therefore, in cases of dispute only the tensile strength value ...
The hardness of EN8 and C25 steels during Jominy-type end-quench test was numerically estimated. The cooling curve near the quenched end of the specimen was used to estimate the heat flux during quenching. Heat transfer in the specimen during quenching was modeled as a 2D axisymmetric heat ...
