Abstract
Φ160 mm 0Cr17Ni4Cu4Nb stainless steel bar products are produced at Special Steel Works
Benxi Steel by 3t ESR ingot-800 primary mill blooming 190 mm×190 mm billet - four stand 650 tandem mill rolling process to replace original 3t ESR ingot -forging process.Practice indicated that production effciency
yield and surface quality of products produced by rolling process were better than that by forging process
