NICKEL 200 : Commercial pure wrought nickel for the construction of a chemical plant

NICKEL 201 : A law-carbon grade of nickel free from the stress-corrosion cracking associated with graphitisation in chemical plants operating at temperatures above 30000 t, e.g. Caustic Soda Plant.

NICKEL 205 : A high-purity nickel for anodes, plants and grids of electronic valves and for magnetostriction transducers.

NICKEL 212 : Slightly stiffer than pure nickel, used for electrode support wires in radio valves and tungsten filament lamps

NICKEL 222 : A cathode nickel for the sleeves of indirectly heated, oxide-coated cathodes in radio valves.

NICKEL 270 : A high-purity nickel with a minimum temperature – coefficient of resistace of 0.0060C over the range 0.1000C. Made by the powder metallurgy process. Used for components of special valves, such as hydrogen thyratrons and for electric resistance thermometers and controls.

MONEL ALLOY 400 : A general engineering alloy with good resistance to corrosion by sea water, sulphuric, hydrochloric and phosphoric acids, pharmaceuticals products, ammonium sulfate, fatty acids, etc. It retains its strength and toughness up to about 45000C and is used for chemical, stem and petroleum plant, marine and pickling equipment.

MONEL ALLOY K-500 : An alloy with similar corrosion-resistance to Monel alloy 400 but amenable to precipitation hardening to give high strength. Used for propeller and pump shafts, bolts, doctor blades and valve spindles.

CAST MONEL ALLOYS : Cast alloy pig supplied for foundry addition to silicon. For corrosion-resistance castings. INCONEL ALLOY 600 : This alloy has excellent mechanical properties and oxidation-resistance at high temperatures. It is used for furnace parts, heat-treatment equipment, heating in nuclear engineering and in the construction of chemical plant.

INCONEL ALLOY 625 : An alloy with high strength and toughness from cryogenic temperatures to 10000 C in addition to good oxidation-resistance. It resists attack by other media and is virtually immune to chloride-stress corrosion cracking. It is used in aerospace and is being evaluated for chemical and marine engineering.

INCOLOY ALLOY 800 : This alloy resists hydrogen/hydrogen sulfide corrosion and chlorides stress corrosion cracking. It is based on pigtails and headers and hydrocarbon “cracker” tubes for other high temperature processing equipment.

INCOLOY ALLOY 825 : This product resists corrosion by acids and alkalis in either reducing or oxidizing conditions. It is resistant to stress-corrosion crack and pitting and used for chemical plants and pickling plant. A nickel iron cobalt alloy combining a low coefficient of expansion and higher inflexion temperature with higher strength than is usual in this composition range. It is being evaluated for such applications as diesel engine piston crowns compensation members in gas.
