Heat Treatment Of 9840 Steel Bar Achieving Hardness And Balance - China

9840 steel bar hardness and balance are achieved the key role of heat treatment process

carburizing and quenching: form a high hardness wear-resistant layer (55-62 hrc) on the surface, and keep a low thickness in the core to provide high strength.

normalizing: improve the impact toughness and uniformity of the material by refining the grain.

low-temperature tempering: eliminate internal stress while maintaining surface stiffness and fatigue resistance.

synergistic effect nickel and chromium work together to improve the hardenability and tension of the material, making it suitable for complex coating and deformation requirements.

the addition of molybdenum improves high-temperature performance and prevents premature failure.

processing and manufacturing strategy

precision machining: complete most of the processing before heat treatment to reduce processing heat and heat treatment deformation.

surface strengthening technology: improve fatigue resistance and surface strength through rolling or shot peening.
