PRODUCT DESCRIPTION
25CrNiMoV is usually produced by EAF + VD + LF / EF followed by electroslag refining (ESR) 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 black in the annealed condition.
Heat treatment condition- normalized + tempered, quenched + tempered.
TECHNICAL SALES ASSISTANCE & 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.
