Specialist Technologies

Specialist technologies

A set of differentiated processes giving customers the ability to produce unique high value-adding products.

Hot Isostatic Pressing Services (HIP)

Impact resistance and fatigue properties are extremely sensitive to small amounts of porosity. Through the simultaneous application of heat and pressure, the HIP process eliminates internal porosity, improving fatigue strength, tensile ductility and fracture toughness.

Hot Isostatic Pressing Product Fabrication (HIP PF)

This method combines the HIP process with design and production expertise to create a component from metal powder. The flexibility of the HIP PF process means that combinations of materials can be used to give desired properties, enabling metallic compositions that are difficult or impossible to forge or cast.

Specialty Stainless Steel Processes (S3P)

Steel is often chosen for its inherent corrosion resistance, but often requires hardening. Standard heat treatments will harden the steel, but can negatively impact the corrosion resistance. S3P technology uniquely hardens stainless steel, nickel-based alloys and cobalt-chromium alloys improving mechanical and wear properties without adversely affecting corrosion resistance.

Low Pressure Carburising (LPC)

A case hardening process used to obtain a hardened surface and tough core, giving increased wear resistance and fatigue life, with minimal risk of treatment distortion. LPC is a clean process, carried out under vacuum, and is an environmentally friendly treatment.

Corr-I-Dur® (CiD)

A proprietary thermochemical treatment for the simultaneous improvement of corrosion and wear resistance through the generation of a nitride-oxide combination layer. Corr-I-Dur® is an environmentally friendly alternative to the use of hard chromium, electroless nickel and other galvanic coatings.

Surface Technology (ST)

ST incorporates specialised plasma spray, High Velocity Oxygen Fuel (HVOF) and thermo-chemically formed coatings to improve wear resistance, hardness and durability, and is able to surface engineer components designed to operate in the most demanding of industrial applications.

Classical Heat Treatment

Classical heat treatment

A group of mature processes which are essential for treating all metal components. These tightly controlled processes condition the material properties including both the core properties and the surface characteristics.

Below are a few examples of material properties obtained by heat treatment:

Surface hardness

What is it? The ability of a material to resist deformation, scratching and indentation under force.

Why is it important? Improving a material's hardness through heat treatment allows it to resist various types of wear.

Toughness

What is it? The ability of a material to absorb energy and plastically deform without fracture.

Why is it important? Heat treatment can be used to strengthen the material and help improve its resistance to impact.

Fatigue strength

What is it? The stress level at which component failure occurs when subjected to repeated stress cycles.

Why is it important? Part failure due to fatigue can have catastrophic consequences, particularly if the part is safety critical. Through heat treatment, a material's fatigue strength is improved.

Creep resistance

What is it? The measure of a material's ability to resist high temperature deformation.

Why is it important? Some metals and alloys must operate at temperatures close to their melting point. Heat treatment enables them to perform at higher temperatures with little or no movement.

Core ductility

What is it? The ability of a material to deform without breaking.

Why is it important? In order to form or shape a complex component good ductility is required. Heat treatment is used to soften the material which makes it easy to work as part of the manufacturing process.
