This alloy is extensively utilised in corrosive environments with high chloride and high temperature conditions, such as flue-gas scrubbers, nuclear fuel reprocessing, sour gas handling, and pesticide production.
GRCop-42
Copper/chromium/niobium alloy was developed by NASA specifically to additively manufacture parts in need of high-strength dispersion and high conductivity. Due to the use of chromium and niobium in the alloy, it retains strength at high temperatures, exhibits excellent creep resistance, and has a low cycle fatigue life. It is invaluable for rocket engine components such as fuel injector faces & combustion chamber linings with regenerative cooling. Valuable for rocket engine components such as fuel injector faces and combustion chamber linings with regenerative cooling.
Haynes 282
Introducing a wrought, gamma-prime strengthened superalloy engineered for high-temperature structural applications, such as those in the aerospace and industrial gas turbine engines. It possesses a unique combination of creep strength, thermal stability, weldability, and fabricability, which is not currently available in commercial alloys. It is ideal for high-temperature applications such as gas turbines and components in the power and process industries.
Haynes 214
Haynes 214 alloy (UNS N07214) is a nickel-chromium-aluminium-iron alloy, developed to provide the optimum high-temperature oxidation resistance for a wrought austenitic material, all while allowing for conventional forming and joining. Intended principally for use at temperatures of 955°C and above, Haynes 214 alloy exhibits resistance to oxidation that exceeds many conventional heat-resistant wrought alloys at these temperatures. This is attributed to the formation of a tightly adherent Al2O3-type protective oxide scale. This oxide scale also makes Haynes 214 ideal for use in high-temperature oxygen environments found in some rocket engines in the pre-burner and main combustion sections.
Inconel 718
A precipitation-hardenable nickel-based alloy known for having superb tensile strength under extreme pressure and heat. It has rupture strength at temperatures of up to 980°C and is characterised by its superb fatigue, creep, and corrosion resistance in extreme environments. It is ideal for applications in gas turbines and parts for the power and process industries, including aerospace, defense, and chemical sectors.
Inconel 625
A nickel-based superalloy that possesses high strength properties and resistance to elevated temperatures, Inconel 625 shows remarkable protection against corrosion and oxidation. Its ability to withstand high stress and a wide range of temperatures, both in and out of the water, as well as its resistance to corrosion while being exposed to highly acidic environments, sets it apart. It is an ideal choice for nuclear energy and marine applications.
Titanium 6Al-4V
