DIN EN 10088-1 Technical specifications of DIN 1.4424 duplex stainless steel, Round bar, Flat bar, Plate, X2CrNiMoSi18-5-3 Forging, Heat treatment, Cold worked.
MATERIAL DATA SHEET - DIN X2CrNiMoSi18-5-3 & W-Nr 1.4424
MATERIAL TYPE: austenitic-Ferritic duplex corrosion resisting steels
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / VOD followed by electroslag refining (ESR) / VAR if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
Bars are usually supplied black/bright in the annealed condition.
Final heat treatment - solution treatment / QT

Maraging steels are iron-nickel alloys with absence of carbon and have metals such as molybdenum, cobalt, titanium and aluminum.
The alloys have ultra-high strength, superior toughness characteristics and weldability. Typically, these alloys are used in aerospace applications, machinery and tooling and ordnance components and fasteners.
