Alloy carburizing steel performance requirements

Sep 07, 2015

(1) carburized layer of high hardness, excellent wear resistance and to ensure that the contact fatigue resistance, while having adequate ductility and toughness.

(2) central portion having high toughness and high enough intensity. The heart is insufficient toughness under impact load or loads too easily broken; insufficient strength, the more brittle carburized layer easily broken, peeling.

(3) have a good performance at high heat treatment process of carburizing temperature (900 ℃ ~ 950 ℃), the austenite grain is not easy to grow up and have a good hardenability.
