INFLUENCE OF MANGANESE AND CARBON ON THE PROPERTIES OF W-Cr NON-DEFORMING TOOL STEEL (I)

Abstract

To investigate the influence of manganese and carbon on the properties of oil-hardening non-deforming tool steel containing 1·05% carbon, 1·2% tungsten and 0·75% chromium, the authors measured the critical point, Jominy hardenability, S-curve for the transformation of austenite, quenched and tempered hardness, retained austenite, dimensional changes and toughness.
