654 SMO® can be considered a “lean Ni-alloy” since it contains significantly lower levels of costly nickel and molybdenum than common Ni-alloys. The grade nevertheless offers similar or better mechanical properties and corrosion resistance, which translates into price stability and cost savings in a host of applications. The superior properties of 654 SMO® also give it many advantages over other highly-alloyed stainless steels and titanium. 654 SMO® data sheet 

Plate heat exchanger manufacturers are a typical example of a customer group that can benefit greatly from 654 SMO®. The grade’s exceptional mechanical and physical properties are useful when pressing complex heat exchanger plates from thin sheets, while the grade’s high corrosion resistance to chemical products and seawater make it the economical solution for a wide range of applications.

Another interesting example is condenser tubing for nuclear power plants, where titanium can suffer so-called “droplet erosion.” The higher erosion resistance and superior stiffness of 654 SMO® can allow for thinner tubing walls and increased reliability over titanium. The grade has successfully replaced titanium in the most aggressive areas of Swedish and Finnish nuclear power plants.

Other application areas where 654 SMO® can offer a distinct advantage include flowlines, seawater cooling as well as filters for off-gas handling systems and other flue gas cleaning applications.

654 SMO® is a proven solution for environments requiring a combination of superior corrosion resistance and mechanical properties.
