Introduction
It is a typical representative of chromium-molybdenum-vanadium powder steel belonging to Swedish standards. The same series of powdered high-speed steel from Sweden's ASSAB is sometimes written as powdered high-speed steel.
Main uses
Particularly suitable for blanking and forming thin materials to be processed or those with a high risk of plastic deformation on the surface, such as
Crushing of parts of plastic molding machines such as screw barrels, nozzles, injection heads Knife for blanking carbon steel or high carbon steel, punching hardened steel plates or cold-rolled steel strips, plastic molds containing glass fiber
Product Features
High wear resistance, high compressive strength, toughness, good heat treatment dimensions Good stability, good resistance to tempering and softening, very good hardenability]

Surface treatment
Many cold work mold applications must use surface treatment to reduce surface friction The most commonly used surface treatment to increase the wear resistance of molds is titanium nitride carbide titanium nitride surface coating (.
It is especially suitable for titanium carbide titanium nitride surface coating. Because the carbide distribution is very uniform, the coating bonding is better and Reduce dimensional changes during the mold hardening process. Due to the combination of high strength and high toughness, it becomes the most ideal base material for plating molds.

Heat treatment
) The usual method for soft annealing Guanding Special Steel is to heat to ℃ in a protected state, then soak in the furnace at ℃ every hour, and then cool in the air to ℃.
) After rough machining, the stress relief mold should be heated to ℃ and soaked for several hours, then slowly cooled to ℃ in the furnace and then cooled in the air.
) Hardening (quenching) treatment
Preheating temperature ℃ and ℃
The quenching temperature is selected according to the required hardness. The mold must be protected during the hardening process to avoid oxidation and decarburization.

Surface treatment
According to Dongguan Guanding Engineers from Metal Materials Co., Ltd. introduced that the processing and heat treatment of high-alloy tool steel are usually more difficult than that of low-alloy tool steel, so the manufacturing cost of molds is also extremely high. The machinability of powder metallurgy-made high-alloy tool steel is better than that of high-alloy tool steel made by traditional methods. Fortunately, the dimensional stability of heat treatment is also relatively good and easy to predict. Moreover, due to its high hardness, high toughness and high temperature tempering characteristics, it is particularly suitable for surface treatment such as titanium plating.
Mold life
Use the correct hardness for different purposes
High wear resistance
High toughness to avoid early mold failure due to chipping or cracking
According to an engineer from Dongguan Guanding Metal Materials Co., Ltd., high wear resistance will reduce the toughness of the mold. Therefore, many examples show that having both high wear resistance and toughness is the most important to the life of the mold.
