Our duplex stainless steel castings represent advanced corrosion-resistant alloy technology for demanding industrial applications. Available in multiple grades including CD-4MCu, CD-4MCuN, CD3MCuN, CE3MN, and CD3MN, these castings combine austenitic and ferritic microstructures to deliver exceptional performance where standard stainless steels fail. Each casting undergoes rigorous quality control to ensure consistent microstructure, proper phase balance, and defect-free construction. We provide reliable configurations to meet specific dimensional, pressure rating, and service condition requirements while maintaining the intrinsic material properties that make duplex stainless steels superior for challenging operational environments.

These castings serve critical functions across multiple heavy industries where component failure is not an option. In chemical processing, they handle concentrated acids, chlorides, and abrasive slurries in reactors, heat exchangers, and piping systems. Th...

Our duplex stainless steel castings represent advanced corrosion-resistant alloy technology for demanding industrial applications.

Each casting undergoes rigorous quality control to ensure consistent microstructure, proper phase balance, and defect-free construction. We provide reliable configurations to meet specific dimensional, pressure rating, and service condition requirements while maintaining the intrinsic material properties that make duplex stainless steels superior for challenging operational environments.

These castings serve critical functions across multiple heavy industries where component failure is not an option. In chemical processing, they handle concentrated acids, chlorides, and abrasive slurries in reactors, heat exchangers, and piping systems. The oil and gas industry relies on them for wellhead equipment, Christmas trees, and subsea components exposed to sour gas and seawater. Desalination plants utilize these castings for high-pressure reverse osmosis systems and brine handling equipment. Additional applications include pulp and paper processing, pharmaceutical manufacturing, marine hardware, and power generation systems where corrosion resistance and structural integrity are paramount for continuous operations.

The value of selecting our duplex stainless steel castings extends beyond initial material specifications to total cost of ownership and operational reliability. These components offer significantly longer service life than conventional stainless steels, reducing replacement frequency and maintenance downtime. Their high strength-to-weight ratio allows for lighter section thicknesses without compromising performance, potentially reducing material costs. We ensure reliability through strict process controls, material traceability, and comprehensive testing including PMI, radiographic examination, and mechanical property verification. Our manufacturing capabilities mean you get components engineered specifically for your application requirements rather than adapted from standard offerings.
