Cold-work die steel material and alloy alterant

Abstract

The invention relates to a cold-work die steel material and an alloy alterant. The cold-work die steel material is characterized in that: besides Fe, the material further comprises the following elements by weight: 1.55-1.75% of C, 11.50-12.50% of Cr, 0.20-0.30% of V, 0.45-0.55% of Mo, not more than 0.25% of Si, not more than 0.20% of Mn, not more than 0.030% of S, not more than 0.030% of P, not more than 0.15% of Ni, not more than 0.2% of Cu, and the balance Fe, wherein sum of weight percentage of each element is 100%. Compared with the prior art, the cold-work die steel material is used for casting, and the alloy alterant is added for raising performances of the cold-work die steel material. A cold-work die module is made by a casting technology, which saves energy, reduces waste of materials, and greatly shortens a production cycle.

Description

technical field [0001] The present invention relates to cold work die steel, more specifically, relates to a kind of cold work die steel material and alloy modification agent. Background technique [0002] Existing cold work die steels cannot be applied to casting, or the castings obtained by casting have defects in performance. Therefore, the traditional cold work die raw materials are mostly modified by the direction-changing forging method. The main forging process is: upsetting-drawing- The disadvantages of upsetting are: the forging process is complicated, the cost is high, and the processing efficiency is low, and the forging module is a simple square or cylinder, which is quite different from the actual shape of the cold working die module, and it needs to be machined again. In the machining process after forging, the amount of machining is large, which will cause a lot of waste of materials and energy. Contents of the invention [0003] The technical problem to be...
