Network optimisation information.

The thermal fatigue resistance index can be measured by the number of thermal cycles in which thermal fatigue cracks sprout, the number of fatigue cracks, and the average depth or length after a given thermal cycle.

Bite force.

Occlusion resistance is actually the resistance when cold welding. This characteristic is very important for mould materials. Normally, under dry friction conditions, a tool steel specimen is subjected to a constant velocity double friction movement with the material (e.g. austenitic steel), with the load gradually increasing at a certain rate. At this point the torque also increases accordingly. This load is called the "bite critical load" and the larger the value, the greater the bite strength.

Use.

Due to the wide range of moulds used, the working conditions of various moulds vary greatly, so the range of mould materials used in the manufacture of moulds is very wide. Similar to maraging steel, such as carbon structural steel, carbon tool steel, alloy structural steel, alloy tool steel, spring steel, high-speed tool steel, rust-resistant and high-temperature resistant die steel, etc. Die steel cr8 is used to meet the needs of special moulds, but also for powder high speed steel and powder high alloyed die steel, etc.
