1) Remark: Material EN-GJMW-450-7 (former GTW-45-07 acc. to DIN 1692-82) is a white malleable cast iron which is used for clutch parts (coupling jaw) and differential cases. Malleable iron can be used for pressure equipment, e.g. fittings (with thread, with clamp joint) for compressed-air, water (hot and cold), oil, steam, gas as well as for industry fittings (housings, covers, upper parts) and diaphragm valves. The appropriate materials for pressure applications and the conditions of use are specified in special product standards or application standards. For the structuring of pressure equipment special construction guidelines applies.
