3D Metalforge develops Additive Manufacturing parameters for super duplex stainless steel

April 20, 2022

3D Metalforge Pte Ltd, headquartered in Singapore, has developed Additive Manufacturing parameters for super duplex stainless steel. Super duplex is a stainless-steel alloy that has improved strength over ferritic and austenitic steel grades, ideal for high-strength and anti-corrosion parts.

3D Metalforge states that it sees opportunities for super duplex Additive Manufacturing application in the oil & gas and defence industries, especially for heat exchangers, offshore platforms, chemical processing equipment, boilers and pressure vessels. Super duplex steel’s microstructure provides good stress corrosion cracking (SCC) resistance, which makes it suitable in situations of elevated temperature or humidity which is not the case for standard austenitic stainless steels.

The development of super duplex for Additive Manufacturing is said to be significant to 3D Metalforge’s continuing commitment to leading the way in the development of new Additive Manufacturing technologies and materials. The development of the build parameters for super duplex has taken over six months due to the difficulty in achieving the necessary mechanical properties. The benefit of being able to additively manufacture in super duplex widens the range of parts that 3D Metalforge can produce, thus widening its customer base. It’s also expected to allow 3D Metalforge to explore new custom-engineered solutions and streamlined processes to deliver a faster response and shorter turn-around times that customers need.

Matthew Waterhouse, 3D Metalforge’s Managing Director, stated, “We work continually to expand our library of available metal and polymer materials to meet clients’ increasing demand for specific, high-performing materials approved for AM application – and this is key to 3D Metalforge continuing to provide better performing quality AM parts. The application of super duplex will enhance our production of high-demand industrial parts faster, better and more cost-effectively than traditional manufacturing. The ability to produce parts in super duplex, along with our complete range of AM services, gives us a competitive advantage, while we improve companies’ processes, and their products and services.”
