DIWA 353 withstands operating temperatures of up to 400 C and can be used in the steam drums of subcritical power-generating plant systems. This steel is usually supplied in normalized and tempered state. In plate thicknesses ranging from 6 to 150 mm (0.24 to 5.91 in.), DIWA 353 is based on the standardized 23MnNiMo5.4 grade (Material No 1.8807), VdTÜV Material Data Sheet 384. This datasheet provides information on composition, physical properties, and tensile properties as well as fracture toughness. It also includes information on high temperature performance as well as forming, heat treating, and joining. Filing Code: SA-623. Producer or source: Dillinger Hütte GTS.
