    Thermal Stress Relieving

    Thermofax has over 45 years of experience in sub-contract heat treatment services and has now gained an impressive reputation for providing its customers with a range of quality services.

    We offer a range of services to meet the exact needs of our customers including Annealing, Normalising, Heat Treatment Stress Relieving, Hardening, Procurements, Tempering and Special Processes at our customers´┐Ż requests.

    We provide our services to a broad spectrum of industrial sectors some of which include Petrochemical, Oil and Gas, Aerospace, Marine, Defence, Food Processing, Power Generation and Agriculture.

    Our 25,000 sq. ft heat treatment plant is now one of the largest privately owned facilities in the UK capable of providing a range of consistent high quality services including:

    Thermal Stress Relieving
    Thermofax provides heat treatment services to include the thermal stress relieving of large components and materials to reduce the internal stresses without substantially modifying their internal structure.

    These include post weld stress relieving to procedure including: ASME VIII, ASME IX, BS31.1, BS31.3, and PD5500:2009, stabilizing treatments and profile or manipulation stress relief.

    We provide a range of specific Annealing services for our customers including Full Annealing, Inter Critical Annealing, Isothermal Annealing, Solution Annealing, Spherodize Annealing and Sub Critical Annealing.

    Heat treatment consisting of austenetizing followed by air cooling to materials including Carbon and Alloy Steels, Petrochemical Grades and Power Generation Grades.

    Our Hardening Services include precipitation hardening, solution treatment and ageing for batch sizes up to 2 tonnes and lengths of up to 2.7m.

    Thermofax also provides a Tempering Service for materials and products such as springs and fasteners for batch sizes of up to 10 tonnes and lengths of up to 7.4m.

    Special Processing
    These services include curing, creep flattening, refractory dry out, oxidisation and paint burn off so to find our more specific information about these services please visit our website.

    If by any chance Thermofax cannot provide you with the service you require they will always offer an alternative supplier within the heat treatment community.

    We also offer a number of outsourced services such as flattening, shot blasting, sawing, laboratory testing, straightening and reeling, steel sourcing and chemical cleaning and pickling.

    Thermofax is proud of the quality of service it offers to its customers and have a continued approval to BS EN ISO 9001:2008 the certificate of which can be viewed on its website.

    Materials Processed
    Our website also contains a section and a capacity download sheet for our customers describing the wide range of equipment used along with internal dimensions and craneage capacities.

    Processing A Wide Variety of Ferrous & Non Ferrous Metals
    ´┐Ż- Carbon and Alloy steels, Stainless Steels, Tool Steels.
    ´┐Ż- Aluminium and Aluminium Bronze, Titanium,
    ´┐Ż- SG, Grey and Ductile Cast Irons, Invar And zirconium
    ´┐Ż- Inconel´┐Ż Nimonic´┐Ż Monel´┐Ż and other Nickel Alloys. Copper, Bronze, Brass

    Due to the size of our furnaces we can handle single items up to 6.5 metres in diameter and 16 tonnes in weight and accessibility and access to the site and facility has been designed to accommodate abnormal and oversized loads with the major road being dual carriageway. We can also treat batches of anything from 1 kilo to 30 tonnes offering flexibility and competitive pricing.
