Description
AISI 422 is usually taken a special steelmaking technique by BEF & AOD followed by electroslag remelting (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.
Major applications and features for this type of grade
Engine components.
High strength and boat propeller shafts.
Plastic moulding dies
Corrosion resistant & Heat resistant quality & Polishing performance
