PRODUCT DESCRIPTION
The alloy is usually produced by AOD / BEF 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 condition.
Final heat treatment - solution treatment.
ADVANTAGE & SUPERIOR SERVICE
20+ years Focus On Special Steel Manufacturing and processing.
Stock over 60 grades with a competitive price, along with cutting service for specific requirement.
Customizing special material is welcome.
