Material Specifications EN 10269 of Martensitic Steel 1.4934 Round bar, Flat bar, Forgings, Bolts and Nuts 1.4923 Heat treatment, X22CrMoV12-1 Cold machined.
TECHNICAL SPECIFICATIONS - Grade AMS 1.4934
MATERIAL CATEGORY - High temperature high strength steel and superalloy
PRODUCT DESCRIPTION
The alloy is usually produced by EAF / AOD followed by electroslag refining (ESR or VAR) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied bright in the solution annealing condition.
Final heat treatment - heat treatment / QT / solution treatment.
