Summary Many techniques have been developed over the years to control heat treatment distortion, including the use of different quenching medias, optimization of heat treatment cycles, altering the material chemical composition and even press quenching. Now, learn about Quenching in the 4th Dimension!
SECO/VACUUM's white paper discusses the new 4D Quenching technology, a safe and simple hands-off heat treatment process, minus the challenges of press quenching.
Precision components (industrial bearing races and automotive gears) can distort during heat treatment due to effects of free or unconstrained oil quenching. However, press quenching can be used to minimize these effects. This quenching method achieves the relatively stringent geometrical requirements stipulated by industrial manufacturing specifications. As performed on a wide variety of steel alloys, this specialized quenching technique is presented here, along with a case study showing the effects of prior thermal history on the distortion that is generated during press quenching.
