Diffusion Bonding Projects at Heatric


Diffusion bonding is a solid-state joining process where stacks of plate or sheet are subject to changes in heat and pressure to create a facial weld between the materials.

Heatric first developed diffusion bonded PCHEs over 30 years ago, and has been continuously developing the diffusion bonding process since then. By pushing the boundaries of the technology, Heatric has been able to develop processes for bonding a number of stainless steels and related materials, including (but not limited to):

  • Duplex 2205 (S31803) – duplex stainless steel
  • Dual certified 316L (S31603) – austenitic stainless steel
  • Dual certified 304L (S30403) – austenitic stainless steel
  • Titanium grade 2 (R50400)
  • 6% moly (N08367) Al-6XN super austenitic stainless steel
  • Alloy 617 (N06617) iron-nickel-chromium based alloy

Each of these materials offers distinct benefits making them suitable for a diverse range of applications dependent on the requirements of the customer.

Heatric’s diffusion bonding technology allows for the joining of plates/ sheets in a range of configurations including varied heights and multiple-unit batches. This flexibility of process makes diffusion bonding suitable for a range of applications and Heatric has utilised the process for the manufacture of heat-exchangers, high-pressure valves, chemical reactors, cooling plates, solar absorbers and more.
