In fact, different stamping parts materials have different strength, toughness and wear resistance during the working process of the cold-formed forming machine. Under certain conditions, the use of advanced materials can increase durability several times. Therefore, in order to improve the durability of stamping parts, good materials must be selected.
The Toolox series of materials are a new type of pre-hardened tool steel with high toughness, high wear resistance, and basically no internal stress. And it has a very high degree of purity, a very small grain size, and a very high content of S and P. Due to the special composition design, Toolox series materials have very excellent surface treatment properties. Among them, the surface hardness of Toolox44 can reach HRC65 or more after nitriding, and the surface hardness of Toolox40 can reach HRC62 or more. The surface hardness of Toolox33 can reach above HRC58, and the depth is up to 1.8mm.
The above characteristics of Toolox series materials make Toolox series materials have special advantages in some stamping parts.
1) Thicker steel plate (a typical case of 35mm thickness steel plate), stainless steel plate, and non-ferrous metal plate stamping and forming molds, typically air-conditioning fin molds, etc.
2) Stretching die, stainless steel drawing die.
3) Cold extrusion die. Cold extrusion 304 stainless steel, with a thickness of 0.5mm or more, replaces materials such as DC53, and the effect is very good.
4) The cold roll forming machine uses large stamping parts with high dimensional stability requirements as much as possible.
