Description

According to VdTÜV-Werkstoffblatt 499 : 2002-09, the material NiCr22Mo9Nb with the material number 2.4856 is used for pressure vessels according to TRB 100 and, with interpreting the AD-Merkblatt editions W 2 and W 10 faithfully to their meaning, for temperatures from -196 to 450 degrees. Furthermore, the highly corrosion-resistant nickel-base alloy is used for ranges of applications in nuclear engineering as far as the rules of nuclear engineering or the object-related specifications permit the use of - 196 to 450 °C. The material is resistant to intercrystalline corrosion. With observance of the generally acknowledged rules of technology, the suitability for welding of this material is approved for submerged-arc welding with welding wires, metal arc welding with sheathed stick electrodes or gas-shielded arc welding with welding wires and welding rods. Welding fillers that have been tested for suitability are to be used, such as welding rods, wire electrodes made from SG-NiCr21Mo9Nb (2.4831) and sheathed stick electrodes E-NiCr20Mo9Nb (2.4621). A preheating ought to be dispensed with. The intermediate layer temperature is 150 °C maximum. A plasma-cutting of this material is possible. NiCr22Mo9Nb is contained in the VdTÜV-Wbl 541 : 2001-06 as coating material for seamless compound pipes (base materials 1.0405 and 1.7380). The following is valid for the material according to DIN 17744 : 2002-09 : the nickel alloy is applied in the form of strips, sheets, tubes, bars, wires and forgings for corrosion-resistant and highly heat-resistant construction components. The alloy possesses an extraordinary resistance to pitting, crevice corrosion, erosion and intercrystalline corrosion, and it also is insusceptible to chlorine-induced stress cracking corrosion. Good resistance to mineral acids, such as nitric, phosphoric, sulphuric and hydrochloric acid as well as to alkalis and organic acids. Because of the excellent properties in terms of high-temperature tensile strength and the wear properties together with good resistance to oxidation and carbonizing at the same time, the material is applicable up to 1050 °C. The as-delivered condition solution annealed ought to be chosen for application temperatures of more than 600 °C. In the temperature range 600 to 800 °C, the material has a tendency towards embrittlement. Application for maritime-technology plants, plants for the production or processing of sulphuric, phosphoric, nitric, hydrofluoric and hydrochloric acid and organic acids and alkalis as well as for flue-gas cleaning systems and plants for the processing of natural gas and oil. Processing properties: Formability: good Weldability: good (Werkstoffblatt/Wbl: material specification Merkblatt: specification sheet)
