Choose the evenness raw materials to guarantee the same harden degree

　　Professional wheel loader tooth pin production manufacturer confess that if the choose of the raw materials of the wheel loader tooth pin has unevenness contents, even to only one same tooth pins products, its surface harden degree on the different positions also has a big difference. For example, after the grinding and polishing process, if the middle part of the wheel loader tooth pin is darkness color, but the another parts belongs to light gray color, we can confirm this wheel loader tooth pin simple belongs to the insert casting work pieces.

　　For example, compared with the No 45 steel, professional wheel loader tooth pin production manufacturer said the metal and chemical contents of the No 40 steel is very similar with the first kind metal raw material, so the final wheel loader tooth pin products also has a similar mechanical performance too. But professional wheel loader tooth pin production manufacture can provide the suitable heat treatment to right improve and impute the mechanical performance of teeth pins.
