Keighley Laboratories Ltd specialise in the analysis, testing and heat treatment of metals. We offer a range of metallurgical laboratory services for clients across all engineering sectors, including the marine, aerospace, defence, rail, oil and gas industries. The company has become renowned for its ability to take on contracts of any size and duration whilst ensuring a professional service from start to finish.
As a company that works across some of the most demanding industry sectors, we are relied upon to deliver technical excellence in all areas of sub-contract heat treatment and metallurgical laboratory services. Only a company with considerable resources and experience across multiple sectors can deliver the kind of service that’s demanded by our industry partners. Established in 1920, Keighley Laboratories has both the experience and the resources to meet and exceed those demands.
Our extensive facilities allow us to perform a wide variety of heat treatment and metal analysis tasks – with all procedures carried out by people who really understand and care about metallurgy. To ensure that we’re able to provide the same high level of service for many years to come, Keighley Laboratories Ltd has initiated a policy of continual investment in its people, plant and equipment.
Our team of metallurgy experts have an absolute commitment to quality which ensures customer satisfaction every time, and we can of course provide nationally and internationally recognised quality assurance certification and approvals as required.
The ability to recognise your needs allows us to offer practical advice, guidance and innovative solutions to your problems, and our wealth of application experience ensures that the challenges associated with design, development, manufacturing, processing and testing can all be overcome.
Tell us about the challenges you’re facing and we’ll help you find a solution. Call our experts today on 01535 664211.

At Keighley Laboratories Ltd we offer subcontract hardening of shafts, gears and internal bores, as well as complete in-house manufacture of inductors. (We have hundreds of hardened components available from stock, but can also design and manufacture according to your requirements). Typical carbon and alloy steels processed include 080M40, 070M55, 526M60, 708M40, 817M40 and 534A99.
Press quenching is a process typically carried out after carburizing on thin or complex parts such as gears or cams which tend to distort excessively when quenched in oil. The components are re-heated after cooling from the carburizing process and then oil-quenched on a press using specially designed tooling which holds them to shape. The maximum part diameter we are able to press quench is 0.6m, and the maximum height is 0.25m.
Statistical process control is available for the press quenching process if required.
Some forming operations can make components highly stressed and excessively hard. In these cases, softening operations such as annealing may be carried out. The chief reason to anneal a material is to reduce its hardness for subsequent machining. The process can be carried out at a variety of temperatures - a controlled temperature and controlled or slow cooling is also often necessary to ensure the material’s structure is as desired.
All metallic materials can be successfully annealed - ferrous and non-ferrous. When applied to steels and nodular irons, annealing will increase ductility and provide a controlled microstructure. The process can also be applied to iron castings which exhibit chill.
Joining, forming, casting and machining operations can all create stresses within the subject material. Normalizing is one of the ways of stabilising these stresses. It is used to refine a metal’s microstructure, especially in steels which will require further processing (carburizing, for example), and it is capable of softening and hardening as well as stress relieving, depending on the material’s initial state and chemical composition.
Normalizing is often applied to components which require specific mechanical strength properties. The process helps to ensure future dimensional stability. It is usually carried out on ferrous materials such as steels and irons.

Keighley Laboratories Ltd is able to carry out chemical analysis on a wide range of materials (mainly metal or metal-related) using a variety of different analysis techniques. The most commonly tested materials include iron, steel, stainless steel, aluminium alloys, nickel alloys and foundry products. Techniques used include:
The wide range of materials we test and the multiple techniques we employ makes it difficult for us to give specific turnaround times and prices. We prefer instead to quote each enquiry on an individual basis. Get in touch with your requirements and we’ll get back to you as quickly as possible.
A key function of the Test House at Keighley Laboratories is to test materials and components in order to establish their mechanical properties and structures. This can be done in a variety of ways:
Our metallurgists can also undertake reverse engineering and investigation work in order to determine the cause of material/component failure. Investigations into corrosion, wear, machinability, coating, fabrication and heat treatment problems are all carried out on a regular basis.
Specialist consultancy services include:
Our metallurgists, chemists, engineers and technicians have a wealth of combined experience which covers a broad range of materials, treatments and product types within many different industries.
We are able to carry out weld procedure and welder qualification approval tests to European, American and most International standards, including specialised Aerospace and Defence related standards. We can also offer on-site weld invigilation and provide full documentation as required.
UKAS accredited testing and certification can be carried out to many standards and specifications, including:
Keighley Laboratories Ltd are able to carry out various Non-Destructive Testing (NDT) procedures, including:
Facilities are also in place for specimen and component fatigue testing up to 150kN at ambient temperatures. Operating frequency range is 60-180Hz, dependant on the stiffness of the specimen being tested (resonant frequency). Digital equipment allows us to closely control and monitor functions.
For more information about this service, please get in touch on 01535 664211.
Keighley Laboratories are able to employ a variety of corrosion-resistance testing techniques, including:
Typical specifications include ASTM B117 (NSS), ASTM B368 (CASS), ISO9227 (NSS, AASS and CASS). We can also perform Fog/Dry Cyclic Salt Spray Tests and 100% humidity tests.
