PRODUCT DESCRIPTION
PCrMoV is usually produced by EAF + VD + LF / BEF 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.
Final heat treatment - normalized + quenched + tempered.
TECHNICAL SALES ASSISTANCE & SERVICE
Stock over 60 grades with a competitive price, along with cutting service for specific requirement.
Customizing special material is welcome.
If you are interested in our products or services, pleased to EMAIL (sales@ccsteels.com) our qualified production engineers or sales department.
