Die casting die steel service conditions will be divided into four categories, the tool steel committee of the American Metal Society listed: cold work die steel, hot work die steel and plastic die steel, plastic die steel four categories. Among them, cold work die steel is divided into 12 sub-categories, hot work die steel 9 sub-categories, plastic die steel 2 sub-categories, plastic die steel 5 sub-categories. The selection of each subclass depends on three main factors: 1. Complexity of size and shape
2. Materials to be processed
3, durability requirements or design life
Cold work Dongguan die casting die steel is divided into five groups: Group W, Group O, group A, group D, group S:
1, Group W is water quenched tool steel, there are 11 steel grades, 7 carbon tool steel, carbon content from 0.7% to 1.3% 2, Group O, that is, oil-quenched die steel (commonly known as oil steel), has 4 types of steel, and the carbon content is 0.85%-1.55% 3, Group A is the air-quenched alloy cold work die steel, there are 9 types of steel, the carbon content from 0.5% to 2.25% 4, Group D is high carbon and high chromium cold work die steel, there are 7 steel grades, carbon content 0.9%-2.5% 5, Group S, that is, impact tool steel, there are 7 types of steel, the carbon content of 0.4%-0.6% There are also high speed steel (HSS group) and super high speed steel (SHSS group), cobalt-based cemented carbide and steel-bonded cemented carbide (HA group), powder steel and engineering ceramics (PIM group), carbon tungsten tool steel (F group), special purpose tool steel (L group).
