HOT ISOSTATIC PRESSING 

• Isostatic pressure up to 1400 MPa (megapascal) 

• Temperature up to
2000 ˚C

For more than 30 years, we have been a global leader in Hot Isostatic Pressing technology. Now, because of customer demand, we have extended our capabilities beyond tool HIP to include Powder Metallurgical Steels and Bi-Metallics. We employ a world-renowned flexible production process that enables us to quickly react to changing market needs.

Our HIP products deliver optimum performance and productivity, no matter how challenging your operations.

Tech Data  for HIP
 

QUALIFICATIONS

  • ISO 9001:2008
  • Norsok M650 for MDS D44 (up to 206 mm wall-thickness)
  • Norsok M650 for MDS N01 (up to 186 mm wall-thickness)

HIP Densification Service

Parts with enclosed porosity can be densified under uniform high pressure and temperature, no encapsulation necessary. Final inspection reveals the increase.

(Note: Only closed porosity can be totally eliminated.)

GENERAL PROPERTIES

  • Highest possible density
  • Consistent annealed microstructure
  • Exceptionally high static strength (up to 30%)
  • Superior dynamic strength (up to 100%)
  • Easily polished
  • No new castings required for defective parts
  • No segregation or grain growth

USES

  • Hard metals
  • Castings
  • Reannealing
  • Ceramic wear parts
  • Ceramic medical parts
 

Powder Metallurgy 

Near Net Shapes / Solid Powder Metallurgical Steel

Powder must be encapsulated – so that gas pressure and heat can be uniformly applied to all surfaces during hot pressing—when producing metallurgical parts.  After densification, the capsule is stripped. Quality is assured by ultrasonic measuring and analysis of the polished section. Parts can then be machined to your specifications.

GENERAL PROPERTIES

  • Maximum abrasion resistance
  • Maximum corrosion resistance
  • High strength (with no porosity)
  • Consistent and fine microstructure
  • No phase segregation

MATERIALS

  • Low carbon steels
  • Tool steels (HSS…)
  • Stainless steels (duplex, austenitic…)
  • Nickel-base alloys
  • Cobalt-base alloys
 

Bi-metallics

Solid / Powder

  • Powder and base body encapsulated
  • Pressure and heat uniformly applied to all surfaces
  • Diffusion zone generated

Powder / Powder

  • Cooling channel could be integrated into body
 

GENERAL PROPERTIES

  • Different material properties combined
  • No phase or zone segregation
  • Uniform microstructure
  • Diffusion bonding
  • Solid coatings thicker than 2mm
  • Special steels and hardfaced layers can be applied
 

APPLICATIONS
