FAQs

What is 82B wire rod main application?

82B tire‑cord grade is core raw material for prestressed concrete steel strand, tire cord and high strength steel wire rope.

Can 82B wire rod do multi‑pass drawing?

Yes, 82B is specially designed for multi‑pass deep drawing, but raw material metallurgical quality must be strictly controlled.

What lead‑time for 82B order?

82B high‑carbon grade production cycle longer than low carbon wire rod, lead‑time 10‑20 working days.

Is coil‑splitting service available for 82B?

Splitting service subject to mill technical assessment, please confirm with sales before placing order.

What is risk indicator for bad 82B wire rod?

Bad segregation, high impurity will cause wire break during multi‑pass drawing, we strictly control S & P maximum content.
