Abstract

The invention relates to a die steel. The die steel comprises, by weight, 0.01-0.3 parts of C, 0-0.05 parts of Na, 0.05-0.12 parts of grape stalk, 0.2-0.65 parts of Cu, 0-0.5 parts of Mn, 0.012-0.029 parts of Be, 0.3-0.45 parts of W and 90-95 parts of Fe. The die steel has the advantages of scientific and reasonable component proportions, substantial improvement of the wear resistance, the oxidation resistance and the service life, and toughness increase.

Description

technical field [0001] The invention relates to a mold steel. Background technique [0002] Because cast iron has good casting performance, good processability, and low cost, cast iron is generally used as the material of molds at home and abroad. [0003] However, during the use of existing mold steel, the wear resistance and strength are not high, and engineering plastic materials such as glass fiber and carbon fiber are usually added. Simply using this material cannot improve the service life of the mold and adjust its toughness. Can not meet the needs of enterprises. [0004] Therefore, in order to solve the above problems, a new technical solution is provided. Contents of the invention [0005] The invention provides a mold steel. [0006] The technical scheme adopted in the present invention is: [0007] A kind of die steel, comprises the composition of following weight parts: [0008] Carbon 0.01-0.3 parts; [0009] Sodium 0-0.05 part; [0010] Grape straw 0....
