Impact on Mechanical Properties

Increase in Strength and Hardness: Through the dispersion strengthening of alloy cementite and carbides and the solid - solution strengthening effect, chromium significantly increases the strength and hardness of AB/FH40 steel, endowing it with better load - bearing capacity and wear resistance.

Improvement of Toughness: Within a certain range, the addition of chromium can refine the grains and reduce grain - boundary defects. Thus, while increasing the strength, it also has a certain improvement effect on toughness. However, when the chromium content is too high or there are other adverse factors, such as the formation of a large number of intermetallic compound phases, the toughness may decline.

 

 

 

Enhancement of Wear Resistance: The carbides formed by chromium have high hardness and are dispersed in the matrix. They can effectively resist wear during the friction process and improve the wear - resistance performance of the steel.

Improvement of Corrosion Resistance: Chromium can promote the formation of a passive film on the surface of the steel. When the chromium content reaches a certain value, it significantly improves the corrosion - resistance performance of the steel, enabling AB/FH40 steel to have better anti - corrosion ability in some harsh environments.

Enhancement of High - Temperature Performance: The addition of chromium increases the heat - strength of the steel, improves the strength and antioxidant performance of the steel at high temperatures, and enables AB/FH40 steel to maintain good mechanical properties in a high - temperature environment.
