Sheffield Forgemasters produces the largest and most technically demanding castings in the World.
Sheffield Forgemasters' foundry is one of the largest in the world and can produce finished machined steel components up to 350 tonnes. A casting of this size will start with a liquid steel volume of over 600 tonnes.
Our foundry is equipped with bottom pour ladles which reduces the slag present in castings and, in turn, imperfections in the finished product.
The vast majority of castings produced in our foundry start out as a wooden pattern, which is produced by our in-house pattern shop.
Once finished, the wooden pattern is used to make a mould in sand. The sand is then hardened and the wooden pattern removed.
The sand mould then becomes the final mould into which the liquid steel is poured.
Once the steel has cooled and solidified, the sand mould is removed from the piece and reused in other mould making.
Steel castings from 10kg up to 350 tonnes finished weight, up to 15 metres long and up to 8.5 metres in diameter.
We have state of the art in-house inspection facilities and a multi-skilled NDT team, offering all conventional surface and volumetric inspection. ASME and EN coded welders also offer casting repair, fabrication and cladding services.
We offer a wide range of materials from our foundry, from carbon steel and low alloy grade, up to advanced steels including stainless.
Our main area of expertise includes heavy, complex and difficult castings. Our company has over 200 years' experience in casting steel and we have a wealth of knowledge, from design to delivery and everything in between.
Our castings are used in extremely critical environments, such as Civil Nuclear and Defence, where the material requirements of finished components are exacting.
We are supply complex steels grades such as HY80, HY100 and NQ1, up to thicknesses that most foundries can not match.
Sheffield Forgemasters has a dedicated and highly qualified Research & Development team. The R&D team provides expert analysis, prediction, modelling and design services to various areas of the Sheffield Forgemasters business.
