Cobalt-Restricted Stainless Steel Plate – Nuclear Grade / Nuclear Certified Materials
Nuclear Grade Stainless Steel
Sandmeyer Steel Company has over 70 years experience with supplying nuclear grade and nuclear certified materials to the nuclear energy industry. Since 1952, Sandmeyer Steel Company has been a leading supplier of stainless steel, nickel alloy, and titanium plate products that support critical industries like the nuclear industry with precision and reliability.
Nuclear grade stainless steel is high-purity, corrosion resistant, high strength stainless steel that meets strict requirements for use in nuclear power plants and other nuclear applications. It is often used to fabricate various parts of nuclear reactor implementations, including core parts, shell plates, tube sheets, tanks, steam generators, pools, piping systems, containment structures, pressure vessels, spent fuel storage, heat exchangers and condensers. All of these components require corrosion resistance, high strength and the ability to withstand extreme conditions. Custom plate flanges for piping systems can also be provided, as well as near-net shapes for valves, pumps, and fittings. Additionally, these plates are used in the construction of nuclear waste casks and canisters.

What is Cobalt-Restricted 304L/304 Stainless Steel?
Sandmeyer Steel’s cobalt-restricted 304L/304CO stainless steel is produced with a restricted cobalt content of 0.05% maximum. (Cobalt-restricted stainless steel is also called low cobalt stainless steel.) You don’t have to wait for a mill run or purchase a heat lot quantity – we have it in stock and on site, ready to meet immediate needs.
Key benefits include:
- 0.05% Maximum Cobalt Content – This feature reduces safety concerns related to radiation, a crucial requirement in many nuclear applications
- Exceptional Corrosion Resistance – Withstands harsh environments and extends the lifecycle of components
- Versatile Applications – Suitable for reactor components, storage tanks, steam generators, and other critical infrastructure
