Alloy steel heat treatment process of the role:
C: plays an important role on the strength of steel, but the carbon content should not be too high or too low, too high will affect the welding performance and increased brittleness, low strength of steel would be decreased.
Manganese: strongly increase the hardenability of steel, has little effect on the stability of tempering. Nickel: increase the toughness of the steel, and can improve the impact resistance of low temperature gap, have good fatigue resistance.
To improve the effect of quenching and tempering stability. Mo: to improve the hardenability and tempering stability have significant effects.
Mo: to improve the hardenability and tempering stability have significant effects.
Cr: significantly improve the hardenability of the steel and enhance the stability of the temper, to improve the wear resistance of steel and steel oxidation, corrosion resistance. Chromium is promoting the temper brittleness of elements, in the given conditions of temper brittleness with increasing chromium content and more pronounced.
Shenzhen Su's heat treatment has been trying to study, improve heat treatment process!
