2.4606 (DIN 17744 : 2002-09)	2.4606	DIN 17744 : 2002-09	DIN 17744 : 2002-09 replaced by DIN 17744 : 2020-12	Replaced	Germany	NiCr21Mo16W	The material 2.4606 with the material number 2.4606, which is also contained in the VdTÜV-Werkstoffblatt 515 : 2001-09, is applied in the form of strips, sheets, tubes, bars, wires and forgings for corrosion-resistant construction components. The material is a monophase austenitic nickel-chromium-molybdenum-tungsten alloy that is marked by an oustanding resistance to corrosion in many mediums. The high content of nickel and molybdenum causes good corrosion behaviour in reducing mediums, whereas the high chromium content results in resistance to corrosion in oxidizing mediums. Molybdenum and tungsten support the resistance to local corrosion, especially to pitting corrosion. The low carbon content minimizes the grain boundary precipitation, so that the resistance to corrosion remains in the heat affected zones of welded joints. The material 2.4606 is applied in the chemical industry, in the paper and cellulose industry, for the treatment of industrial and urban waste products. In the chemical industry, fields of application of the material include heat exchangers, reaction boilers, evaporators and tubes for the matter transport. Furthermore, the alloy is applied for numerous construction components for devices of the air pollution monitoring. The material is authorized for pressure vessels (according to TRB 100) from -196 to +450 °C. (Werkstoffblatt: material specification)	-196 - 450
