Heat treatment
Sheffield Forgemasters carries out in-house heat treatment to achieve critical mechanical properties in castings and forgings, using controlled furnace, quenching and cryogenic processes across a wide range of steel grades.
Heat treating capabilities
Heat treatment at Sheffield Forgemasters supports hardening, annealing, and solid-state hydrogen diffusion across carbon, low alloy, and specialist steels. These treatments are applied at different production stages to develop the required mechanical properties in castings and forgings. All operations are backed by rigorous quality assurance, with thermal modelling used where needed to safeguard structural integrity in demanding applications.

Quenching
Sheffield Forgemasters offers both oil and water quench areas to provide a range of cooling rates. These differences influence the final material characteristics. Our largest quench tank measures 7.4 metres wide and 5 metres deep, includes agitation jets for high turbulence, and holds 79,000 gallons of water, fed constantly with fresh cold supply during operation.
Cryogenic Hardening
Two cryogenic cooling tanks are available onsite, capable of reducing steel temperatures to -130°C. This treatment increases strength and hardness in the material being processed by refining its internal structure. Cryogenic hardening is used where increased strength and hardness are required for demanding applications, supporting specific material applications across demanding industrial environments.
Heat Treatment Hire for External Projects
Sheffield Forgemasters’ large-scale, computer-controlled furnaces support everything from precision components to ultra-large castings. Facilities are also available for third-party hire, offering flexible options for specialist treatments across a range of steel grades.
