M2Al is a cobalt-super-hard high speed steel, vacuum heating to promote abnormal grain growth. Implementation of an inert gas can improve the heating rate of vacuum heating, hinder the formation of unusually large crystal grains improve the strength and toughness of the steel M2Al. The main factors affecting the strength and toughness of the steel is not M2Al mixed crystals and size of austenite grain size, but the shape and distribution of carbide steel. In order to play super hard M2Al steel vacuum quenching temperature can be increased, so that the hardness of 66HRC or more. Shipping
