2.4633 (DIN EN 10302 : 2008-06)	2.4633	DIN EN 10302 : 2008-06	Supersedes DIN EN 10302 : 2002-09	Valid	Germany	NiCr25FeAlY	According to VdTÜV-Wbl. 540 : 2002-09 (Wbl. = material specifications), the material NiCr25FeAlY, material number 2.4633, is used for pressure vessels according to TRB 100. In conveying the general sense of the AD specifications sheet W2, it is used in temperatures ranging from -10 to 1150 degrees C (reduced use in temperatures from >500 to 650 degrees C). Furthermore, the highly carboniferous nickel base alloy is used in nuclear technology in as far as the rules of nuclear technology and the specifications opf the object allow the use in temperatures between -10 and 1150 degrees C (reduced use in temperatures from >500 to 650 degrees C). Due to a tightfitting layer of aluminium oxide and an increased Cr and Al content, the material possesses in the as-delivered and in the same-type welded condition a high resistance to oxidation and and a good resistance in oxidizing and sulfur-bearing atmospheres in increased temperatures. It is weldable in consideration of the generally valid rules of welding technology, restrictions according to the manufacturer for metal arc welding, metal protective gas/active gas welding or tungsten plasma welding (welding filler: sheathed welding rod EL-NiCr25FeAl, welding rod or filler wire SG-NiCr25FeAl). Pre-heating is not permissable, the intermediate layer temperature must not exceed 120 degrees C. A heat treatment after welding is usually not necessary. The material can be plasma cut. For impairments of the toughness behaviour in operation temperatures of >500 bis 650 degrees C, see VdTÜV-Wbl 540 : 2002-09, sections 16 and 17 [Wbl. = material specifications]. According to DIN 17742 : 2002-09, the material NiCr25FeAlY is used for furnace parts such as belts, sheets, pipes and rods. It is a highly carboniferous nickel-chrome-iron alloy with aluminium and yttrium as additives. It is characterized by extraordinary resistance to oxidation at high temperatures and also in cyclical conditions, a very good resistance to corrosion in carbonizing media, an excellent high temperature strength, as well as a precipitation hardening temperature of up to 800 degrees C. It is used in thermo-technical and chemical procedures and in power station technology, for example as steel pipes, furnace rollers, muffles in bright annealing furnaces (hydrogen atmosphere), furnace parts, pipe mountings, components in exhaust gas systems and exhaust gas decontamination, as well as pig-tails in ethylene plants. Processing properties: formability: good weldability: good	-10 - 1150
