The production of our company's super duplex stainless steel plates is in order. Since the beginning of this year, our company has continued to increase its research and development efforts on duplex stainless steel, and has successively broken through the problems of narrow range control of surface roughness of economical duplex stainless steel cold plates and control of microstructure uniformity of ultra-thick steel plates, achieving a super-thickness of 115 mm. The mass production of duplex stainless steel plates will further assist the localization process of materials for petrochemical, papermaking, offshore platform and other projects.
