Increased hardness & wear resistance with Marbain chart

Fisher Barton materials expertise provides improved methods for producing parts.

Reduced costs, manufacturing lead times with Marbain products

Fisher Barton provides solutions to your manufacturing problems.

At Fisher Barton South Carolina (FBSC), we offer many unique services and processes that give us a competitive advantage over other precision metal stamping facilities. The best and most unique of these are our exclusive MARBAIN® base material, which is optionally available for part and component construction, and our austempering heat treatment process for improving the strength and overall quality of completed parts.

FBSC developed an exclusive, proprietary and patented base material for part fabrication, called MARBAIN®. As a base material in component production, Marbain offers many advantages for our customers looking for alternatives to steel. These advantages include:

  • increased hardness
  • higher yield strength
  • higher bend resistance
  • greater impact toughness
  • better wear resistance
  • superior cold formability
  • better, easier machinability

Our understanding of the unique metallurgy of this raw material allows us to develop better manufacturing practices and process improvements, which lead to more efficient fabrication and lower costs for our customers’ product lines.

Fisher Barton South Carolina is one of the largest austempering heat treating facilities in the southeastern United States. Austempering offers a number of advantages versus conventional “quench and temper” heat treating. The quench and temper process typically results in low density, hard, brittle components, and is prone to creating quench cracks, which decrease the quality and strength of the treated components.

FBSC’s austempering process is proven to solve these problems. Our austempering treatments transform steel into a hard, tempered material known as Bainite. Bainite’s slow nucleation and growth during this gradual transformation allows transformation stress to dissipate. There is also an increase in the material’s plasticity due to the high-temperatures required in the Bainite transformation stage. A smaller volume change is associated with this transformation, and Bainite is more ductile than untempered materials, such as Martensite.

Austempering imparts a number of advantageous qualities into treated materials, including:

  • less distortion
  • uniform and consistent hardness
  • better wear resistance
  • higher impact and fatigue strengths
  • hydrogen embrittlement resistance

Using our unique MARBAIN® material and austempering processes, Fisher Barton South Carolina has been able to effectively design and develop forged harvester blades and other forged agricultural blades to meet the needs of our customers.
