GB / T 1299-2014 “Tool Steel” new standard is related to the original “carbon tool steel”, “alloy tool steel”, “plastic mold steel” and other standards together, re-prepared and supplemented compiled. The standard was released on December 5, 2014 and implemented on September 1, 2015. The new standard according to the use of steel is divided into 8 categories: blade die steel for non-alloy steel (8 steel), the amount of cutting tool steel (6 steel), impact tool steel (6 steel), roller Steel (5 steel), cold work die steel (19 steel), hot work die steel (22 steel), plastic mold steel (21 steel) and special purpose mold steel A steel), a total of steel grade 92.
