The consequences of buying inferior Cr12MoV
Cr12MoV tool steel has high hardenability. The cross section is 300 ~ 400mm. It can harden completely. It can keep good hardness and wear resistance at 300 ~ 400 ℃.
Cr12MoV can be used to make various moulds and tools with large cross section, complex shape and bearing large impact load. It has the characteristics of wear resistance, hardenability, micro deformation, high thermal stability and high bending strength. It is second only to high speed steel. Cr12MoV is an important material for die cold heading. The consumption of cold working die steel(https://otaialloysteel.com/products/tool-steel/)ranks first.
In fact, some unreliable suppliers may, regardless of the interest of the customers, cheat customers with inferior products. These dishonest actions not only disrupt the market. At the same time, it also has a serious impact on customers.
The consequences for end users who purchase these crude Cr12MoV cold work tool steels are as follows:
1) The microstructure of inferior Cr12MoV die steel is seriously segregated. Because of the poor processing performance, drilling and tapping difficulties are often encountered.
2) The deformation of heat treatment is large and the risk of cracking and bending is high. It can’t guarantee the stability of the mold size, affect the appearance of the mold and even scrap.
3) There are many impurities in Cr12MoV die steel after scrap renovation. It makes the mold produce poor red hardness at high temperature. The hardness of the die decreases quickly and the knife edge is easy to wear.
4) The purity of die steel is poor and there are many non-metallic inclusions. The impact toughness of the die is poor, and the knife edge is easy to collapse and fall.
