Material Description

Material Number	Material Number (single)	Standard	Range of Application	Standard Status	Country	Predecessor	Successor	Remark
5.4204 (DIN EN 1562 : 2012-05)	5.4204	DIN EN 1562 : 2012-05	DIN EN 1562 : 2012-05 replaced by DIN EN 1562 : 2019-06	Replaced	Germany	EN-GJMW-550-4	EN-GJMW-550-4	Material EN-GJMW-550-4 is a white malleable cast iron. 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.
