First of all, we actually have to pay attention to wear-resistant castings after quenching, on its own strength is relatively high, the next to say, we actually have to pay attention to its plastic is better.
On the wear-resistant castings after quenching the tensile strength is better than quenched and tempered carbon steel, and low alloy steel quite. Then, the quality of the castings is lighter. Next to say, its bending fatigue strength is the contact fatigue strength and other dynamic load performance is relatively high. Quenched and tempered low alloy steel.
Then, in fact, we should also pay attention to the contact fatigue strength of wear-resistant castings themselves, which is higher than the contact fatigue strength of low alloy steel nitriding treatment.
In addition, the vibration-absorbing properties of wear-resistant castings, then it would be better. In the case of ADI, which has a very low modulus of elasticity and a graphite ball present in the matrix, it is to a very large extent able to quickly absorb vibration and increase its noise damping, This point of speaking, that is, it will make the operation of components will appear more quiet and stable.
Finally, we actually have to pay attention to wear-resistant castings in terms of speaking, that is, there will be better wear and abrasion resistance. On the hardness of 45 ~ 48HRC wear-resistant castings, we actually have to pay attention to its life in terms of speaking, that is, than with martensite or hardness of 58 ~ 62HRC wear-resistant castings longer. As far as this point is concerned, that is, it is suitable for applications requiring excellent wear resistance and sufficient toughness.
