Annealing Heat Treating Heat Treating

Bluewater Thermal's process for annealing stainless steel takes place in two unique stages. First, the metal is softened through the removal of crystal defects that cause internal stresses. Second, comes the nucleation and growth of strain-free grains. This process is completed under very precise conditions.

To avoid oxygenation, scaling, and decarburization, Bluewater Thermal can carry out the process of annealing stainless steel in protective, inert atmospheres such as endothermic gas, hydrogen gas, nitrogen gas, argon gas, or vacuum. Components to be annealed are heated in production furnaces, and then slowly cooled under a controlled environment. Air atmosphere annealing stainless steel is also a low-cost option for raw material and unfinished parts where decarburization and scaling are permitted.

Bluewater Thermal’s facility in Houston, TX specializes in air atmosphere annealing of long raw material products such as bars, tubes, plates, and blocks for the oil and gas industry. Our facilities in Coldwater, MI, and Chicago, IL use continuous mesh belt furnaces for bright annealing of stainless steel products. These furnaces are able to produce brighter parts, with more uniform heating and cooling rates, at lower prices than vacuum furnaces.

Properties After Annealing Stainless Steel
  • Reduced hardness, tensile strength, and yield strength
  • Easier machining and forming of materials
  • Reduced residual stresses
  • No effects of cold-work hardening
  • Recrystallization can eliminate directionality of rolled or forged microstructures and create fine equiaxed grains
  • Homogenization of grain structure to dissipate alloy segregation present in as-cast structures
Annealing Applications
  • Shaping
  • Stamping
  • Forming
  • Hydroforming
  • Bending
  • Machining
  • Castings
  • Forgings
