Evanston, IL., July 22, 2021 — QuesTek Innovations LLC, a global leader in Integrated Computational Materials Engineering (ICME) technologies, in partnership with Daido Steel Co., Ltd., announced today that Ferrium® PH48S™, a castable high-strength stainless steel, is under evaluation for a multitude of demanding industrial applications.
“We’ve had a long-time collaboration relationship with Daido, and they’ve been a great partner to work with in producing and testing our alloys,” said Kerem Taskin, QuesTek’s Principal Applications Engineer. “We look forward to working with them and bringing this material to market for applications.”
To realize the alloy’s full potential, Daido conducted a 50 kg lab-scale trial in Japan in which their engineers produced the steel by Vacuum Induction Melting process. The results found that Ferrium PH48S had higher strength and toughness than conventional precipitation hardening stainless steels, as well as good corrosion resistance. What’s more, it maintained impact toughness at very low temperatures (below 0 degrees Celsius) and also exhibited high-resistance to stress corrosion cracking. These characteristics contribute to weight reduction and miniaturization, which makes Ferrium PH48S viable for oil and gas, aerospace component, and sea vessel component applications. Daido published their results in a Japanese technical publication, Denki Seiko, with the title “Material Properties of Precipitation Hardening Stainless Steel ‘Ferrium® PH48S™’.”
“The results of their testing were encouraging, and we’re finding that there is a growing global demand for this product,” added Taskin.
This pursuit comes in parallel to a demonstrated success with the U.S. Navy. Earlier this year, QuesTek was awarded a NAVSEA-funded SBIR project to evaluate Ferrium PH48S stainless steel as a higher-strength and corrosion-resistant replacement for low alloy steels that were currently used in helicopter tie-downs on Navy vessels. The demonstration of PH48S will prove that it can prevent corrosive wear failure of tie-downs, which are critical for securing helicopters to the flight deck of seaborne vessels.
“We have a singular motivation to create tremendous outcomes: improving mechanical properties versus existing materials, while reducing material and processing costs,” noted Taskin.
