Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country VDA 231-106 classification
0.6660 (DIN 1694 : 1981-09) GGL-NiCr 20 2 0.6660 DIN 1694 : 1981-09 DIN 1694 : 1981-09 replaced by DIN EN 13835 : 2006-08 Replaced Germany 1.2 1)
1) Remark: GGL NiCr 20 2 is more corrosion resistant to alkalis than GGL NiCuCr 15 6 2, well heatproof, good sliding properties, high thermal expansion. The material is comparable to UNS F 41002. Application: For pumps, valves, furnace construction units, sleeves, piston ring carriers for guidance metal pistons, however preferably for alkali pumps, boilers for corroding alkali, soaps -, food -, celanese and plastic industry, use, where generally copper-free materials are necessary.
