Heat Treating

Austemper

Heat treating to provide uniform structure through out material and used to produce MARBAIN®

The Fisher Barton austempering process provides a solution to the expansion problems inherent with conventional quench and temper heat treating. Austempering produces its hardened structure (bainite) gradually and at a relatively high temperature, which provides many advantages. First, bainite’s slow nucleation and growth allows the transformation stresses to dissipate (20-minute bainitic reaction versus instantaneous martensitic reaction). Second, there is an increased plasticity resultant from the relatively high temperatures in the bainite transformation stages. Third, a smaller volume change is associated with the transformation to bainite. Further, bainite is more ductile than untempered martensite.

Enhanced Mechanical Properties: Austempering results in a fine-grained microstructure with improved mechanical properties such as higher toughness, ductility, and fatigue strength compared to conventional heat treatment methods. This makes components more durable and resistant to wear and impact.

Carburizing (Oil Quench & Temper)

Carburizing, specifically using the oil quench and temper method, is a heat treatment process primarily used to enhance the surface hardness and wear resistance of steel components. Oil is used to slow the cooling rate reducing the amount of distortion. Here are the key features and benefits of carburizing with oil quenching and tempering:

Surface Hardness: One of the primary benefits of carburizing with oil quenching is the significant increase in surface hardness. This is achieved by introducing carbon into the surface layers of the steel, forming a hardened case that can withstand abrasion and wear.

Wear Resistance: The hardened case created through carburizing and oil quenching improves the wear resistance of the steel component, making it suitable for applications subjected to friction, impact, and abrasive conditions.

Toughness and Ductility: Despite the increased hardness, the core of the steel retains its toughness and ductility. The tempering process following quenching helps to balance hardness with these properties, preventing brittleness and ensuring the component’s ability to withstand sudden shocks or loads.

Case Depth Control: Carburizing allows for precise control over the depth of the hardened case, enabling customization based on the specific requirements of the application. This flexibility ensures that the desired properties are achieved without compromising the core integrity of the component.

Improved Fatigue Strength: The combination of increased surface hardness and retained core toughness results in improved fatigue strength, making carburized components more resistant to cyclic loading and stress.

Dimensional Stability: Carburizing and oil quenching followed by tempering minimize distortion and dimensional changes in the component, ensuring dimensional stability and maintaining tight tolerances.

Corrosion Resistance: While primarily aimed at enhancing hardness and wear resistance, carburizing can also contribute to improved corrosion resistance, especially in components exposed to mild corrosive environments.
