SUPER DUPLEX STEEL CASTINGS
Extreme Corrosion Resistance. Exceptional Strength.
Super duplex stainless steel castings engineered for hot seawater, sour oil-field fluids, concentrated brines and other highly demanding environments.
THE MATERIAL
Engineered for the most punishing environments.
Super duplex stainless steels are 25Cr grades engineered for demanding corrosion environments, including hot seawater, sour oil-field fluids, flue gas desulphurisation and concentrated brines. BSCPL casts these premium alloys with tight chemistry control, precise heat treatment and rigorous testing.

APPLICATION GUIDANCE
Precision through every stage.
Super duplex castings follow a tightly controlled production route from methoding and melting through heat treatment, verification and final inspection.
DUPLEX STEEL
SIMULATION-BACKED METHODING
+
CONTROLLED MELTING
Casting simulation and methoding are completed before the casting process begins. Controlled melting is carried out with nitrogen control. Complete documentation packages, including material test certificates, accompany every despatch
SOLUTION ANNEALING
Precise solution annealing, typically 1,100–1,140°C, is followed by rapid water quenching.
FERRITE BALANCE
Ferrite balance is verified before mechanical and corrosion testing as specified.
