Introduction Alloy Tool Steel (AISI D7)
Alloy tool steel, carbon tool steel with Si, Mn, Ni, Cr, Mo, V, W and other alloy elements in order to improve the hardenability and toughness, wear resistance and heat resistance of steel.Add Cr and Mn can improve the hardenability of tool steel, according to the requirements, selectively to join or add other elements (adding amount is generally not more than 5%), that is, to form a series of alloy tool steel.It is mainly used in the manufacture of measuring tools and cutters, shock resistant and cold and hot mould and some special purpose tools.
