A German material scientist, along with a group of travel companions, came to the Amazon region for scientific research. In the evening, they camped on the slope of the Amazon. Although there were some unknown stones, they chose to pitch their tents here to talk about the unknown and mysterious things on this land.
When he woke up the next day, the material scientist took out his military dagger and prepared to unload the tent and set out for another destination. His teammates were surprised to find that his military dagger had several small holes, which seemed to have been hit by hard objects, leaving a gap.
The material scientist was very concerned about his dagger, and remembered that the dagger fell to the ground several times when pitching the tent yesterday. So the material scientist kept an eye on it and lay down on the hillside where he slept last night, hitting different stones again and again, using his beloved dagger. Surprisingly, he found that there was a stone he had never seen before. Although his beloved dagger had several more marks, he did not care at all.
The material scientists collected this kind of stone and took it back to their laboratory for research. They successfully extracted a material and found that it has a very magical effect on the hardness, wear resistance and corrosion resistance of alloy steel.
This material is used in the alloy steel for the valve spool of hydraulic valves, realizing the 3 characteristics of wear resistance, corrosion resistance and durability of the valve spool. The valve spool with these 3 characteristic is also the key for AAK hydraulic cartridge valves to open the door of top hydraulic valve brands HydraForce, SUN Hydraulics and HAWE.
AAK hydraulic cartridge valve spool, with 3 features, supplying 3 first-line brands, and service life is not less than 3 years.
