Nuclear Expertise
Steel Dynamics UK is the world’s first ISO 19443 accredited metal service centre, and the UK’s only nuclear-grade stainless processor purpose-built for the sector.
Nuclear power sits at the heart of the UK’s route to net zero and long-term energy security, and we are proud to be a trusted stainless supplier to the country’s new build, operating fleet and decommissioning programmes.
For more than a decade we have supplied critical stainless steel plate and sheet into nuclear applications where provenance, traceability and quality assurance are non-negotiable.
ISO 19443 Approved
ISO 19443 applies the principles of ISO 9001 to the specific, uncompromising demands of the nuclear supply chain, covering any equipment, product or service Important To Nuclear Safety (ITNS).
Steel Dynamics UK was the world’s first metal service centre to achieve it. That pioneering status matters, because the standard wasn’t retrofitted onto an existing multi-metal business; it was the framework around which our nuclear quality system, our facility and our operating procedures were built.


Stainless Only, No Exceptions
Our 100,000 sq ft UK facility processes stainless steel and nothing else. We’ve also made strategic investments in expanding our infrastructure and systems to support the nuclear industry’s growing demands.
-
Separate Stainless Steel and Carbon Steel facilities so no cross-contamination
-
Employees are Suitably Qualified Experienced Personnel (SQEP) compliant
-
Conducting regular in-house ferroxile testing
-
Maintaining a strong PMI material testing program
We learn from experience, question, monitor and follow our accreditations diligently whilst making sure no counterfeit or suspect items enter our supply chain.
Why It Matters For Nuclear
Not all nuclear stainless suppliers are the same, and for ITNS work the distinction is material. A dedicated stainless processor controls the entire value chain from procurement, stockholding, processing, testing and dispatch, in one stainless-only facility, under one nuclear quality system, with no other metal ever entering the building.
Cross-contamination between stainless and carbon steel is one of the most material-critical risks in nuclear fabrication. Eliminating that risk isn’t a process you bolt on with a procedure and a toolbox talk; it requires a facility in which carbon steel simply isn’t present. That's why Steel Dynamics UK are the ultimate in stainless steel processing for the nuclear sector.

When nuclear, chemical, power generation and other high-integrity customers choose Steel Dynamics UK, they are choosing a partner whose entire business model is engineered around the quality assurance they need.
It also demonstrates our commitment to Health & Safety and Quality, and provides all our customers with complete reassurance – not just in nuclear, but in every market sector - that all our materials meet the highest possible standards, representing the very best in class of process and products.
