Description

According to VdTÜV-Werkstoffblatt 345 : 1999-06, the material LC-Ni99 with the material number 2.4068 is applied for pressure vessels according to TRB 100 and AD-Merkblatt from -10 to 600 °C. Besides, the pure-nickel material 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 - 10 to 600 °C. The pure Ni-alloy is in the reviewed dimension range weldable by metal-arc welding with covered rod electrodes (2.4156) as well as gas-shielded welding with (wire) rods (2.4155). No preaheating necessary. The material have to welded in the soft annealed condition. Stress relieve annealing have to be carry out after 5 % cold forming and for reducing of residual stress after welding. The following is valid for the material according to DIN 17740 : 2002-09: it is applied in the form of strips, sheets, tubes, bars, wires and forgings for corrosion-resistant construction components, built-in parts for light bulbs and thermionic valves. LC-Ni99 is a pure nickel of commercial quality and with a reduced carbon content like LC-Ni99.6, which, however, possesses a little higher degree of purity. The reduced carbon content, differing from Ni99.2 or Ni99.6, prevents the formation of embrittling carbon precipitations at temperatures above 315 °C. The permissible maximum operating temperature for sodium hydroxide evaporators is approximately 450 °C. In reducing conditions, e.g. in hydrofluoric and hydrochloric acid, the material offers good resistance to corrosion. In oxidizing conditions, a protective film forms on the surface. This process constitutes the reason for the good resistance to sodium hydroxide, hydrogen chloride (dry) and bromine (dry). Good resistance to stress cracking corrosion, in solutions of caustic alkalies as well as in solutions containing chloride. Application in chemistry and petrochemistry, e.g. for heater tubes, tube plating and circulation plates of the evaporators of a caustic soda plant. Furthermore, for plant components for the salt production, e.g. heat exchangers, centrifuges and valves and fittings. In the food industry for plant components for the processing of food, e.g. fruit juice processing plants. Processing properties: Formability: very good Weldability: good (Werkstoffblatt: material specification Merkblatt: specification sheet)
