PRODUCT DESCRIPTION
The alloy is usually produced by AOD / VD / VIM 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 bright in the softened condition.
Final heat treatment - solution treatment + A
TYPICAL APPLICATIONS
Chemical equipment
Mechanical parts used in the condition of corrosion resistance
Bolts and nuts
Pressure vessel
AVAILABLE FORMS AND DIMENSIONS
Round bar (diameter): 5.5 ~ 550mm
Square bar / flat bar: 8 ~ 650mm
Wire rod (Diameter): 0.10 ~ 16mm
Steel strip & rolled plate: T0.1 - 150mm X W5 - 1500mm X Random length (or in coil form).
Forging piece: Different shapes based on OEM.
Other sizes can be supplied to meet specific requirements.
