- Stainless Steel Materials And Processing
Super stainless steels such as duplex steel, super austenitic steel, tantalum-titanium-zirconium, nickel-based alloys, and other high-performance alloys are available in our current stock.
With long standing relationships with many of the largest producers and stocking distributors across the globe, we specialise in non-standard items and hard to find alloys and product forms.
High-temperature alloys are used by manufacturers of equipment that is subjected to extremely high temperatures, such as jet engines for the aerospace market, gas turbine engines used for power generation and waste incineration, and industrial heating equipment.
Corrosion-resistant alloys are used in applications that require resistance to very corrosive media found in applications, such as chemical processing, power plant emissions control, hazardous waste treatment, sour gas production and pharmaceutical vessels.
Superalloys, also referred to as heat-resistant alloys or high-temperature alloys, are classified into several groups, among which nickel-based and cobalt-based alloys represent the most important categories.
Nickel-based superalloys are specifically designed to maintain high creep strength, excellent oxidation resistance, and superior corrosion resistance at elevated service temperatures, typically up to 1100°C.
For hardfacing applications, our nickel-based superalloy cored wires are 100% compatible with open-die forging operations, including critical components such as shafts, presses, and hammers.
The outstanding performance of nickel-based superalloys is mainly attributed to two key metallurgical mechanisms.
Firstly, alloying elements such as molybdenum, tungsten, cobalt, and chromium significantly strengthen the solid solution. These elements directly enhance the high-temperature strength of the welding deposit.
Secondly, elements such as titanium and aluminium contribute to an age-hardening effect by forming a face-centred cubic (FCC) structure. This structure enables precipitation strengthening, providing maximum mechanical performance under extreme service conditions.
We are a partner for every step in the material value chain, with an extensive product portfolio.
Quality knows no compromise. We deliver materials of the highest metallurgical purity for application in the most extreme environments. We are one of very few suppliers worldwide who have a wide range of melting and remelting plants at our disposal (EAF, VIM, ESR, PESR, VAR).
Our product range includes:
Long-standing customer partnerships, customer-oriented research & development, simulation activities, customized heat and surface treatment, as well as logistic solutions testify to our competence and expertise.
