Corrosion-resistant alloys are our specialism. Every grade below is available across our product range — pipes, tubes, fittings, flanges, valves and instrumentation — with EN 10204 3.1 certification and PMI verification on request.
The workhorse grades of process industry — excellent general corrosion resistance, weldability and availability. 904L and 6Mo extend performance into chloride-rich and acidic environments.
Twice the strength of austenitic stainless with outstanding resistance to chloride stress-corrosion cracking and pitting — the default choice for offshore and seawater service.
For the most aggressive environments — hot acids, sour gas, high temperatures and reducing media where stainless steels fail. Full traceability on every heat.
Titanium offers unmatched seawater and oxidising-acid resistance at low weight; copper-nickel resists biofouling and erosion in marine cooling and firewater systems.
