AL-6XN (UNS designation N08367) is a type of weldable stainless steel that consist of an alloy of nickel (24%), chromium (22%) and molybdenum (6.3%) with other trace elements such as nitrogen. The high nickel and molybdenum contents of the AL-6XN alloy give it good resistance to chloride stress- corrosion cracking.
Waspaloy is an age-hardenable, nickel-based superalloy with excellent strength properties through temperatures of roughly 980°C (1800°F). Other characteristics of Waspaloy include good corrosion resistance, as well as being relatively impervious to oxidation making it well suited for service in extreme environments.
Working at Inco's Wiggin facility at Birmingham in the United Kingdom, Leonard Bessemer Pfeil is credited with the development of Nimonic alloy 80 in 1941, and used in the Power Jets W.2B. Four years later, Nimonic alloy 80A followed, an alloy widely used in engine valves today. Progressively stronger alloys were subsequently developed: Nimonic ...
Like other nickel/iron compositions, Invar is a solid solution; that is, it is a single-phase alloy.In one commercial grade called Invar 36 it consists of approximately 36% nickel and 64% iron, [4] has a melting point of 1427C, a density of 8.05 g/cm3 and a resistivity of 8.2 x 10-5 Ω·cm. [5] The invar range was described by Westinghouse scientists in 1961 as "30–45 atom per cent nickel".
Inconel alloys are oxidation- and corrosion-resistant. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high-temperature applications where aluminum and steel would succumb to creep as a result of thermally ...
Monel alloy 405, also known as Monel R405, is the free-machining grade of alloy 400. [24] The nickel, carbon, manganese, iron, silicon & copper percent remains the same as alloy 400, but the sulfur is increased from 0.024 max to 0.025-0.060%. Alloy 405 is used chiefly for automatic screw machine stock and is not generally recommended for other ...
Chromel A is an alloy containing approximately 80% nickel and 20% chromium (by weight), with low-level quantities of Si (1%), Fe (0.5%), and Ni. [2] It is used for its excellent resistance to high-temperature corrosion and oxidation. It is also commonly called Nichrome 80-20, and is used for electric heating elements.
