Material Description

Material Number Material Name Material Number (single) Standard Standard Status Country VDA 231-106 classification
1.6723 (WL 1.6723 : 1992-08) 15NiCrMo16-5 1.6723 WL 1.6723 : 1992-08 Valid Germany 1.1.1 1)
1) Remark: The case hardenable nickel-chromium-molybdenum aerospace steel is used for components with high core strength, very high toughness and larger dimensions, e.g. toothed wheels, bevel gears and shafts. The steel is not resistant to corrosion and only limited weldable.
