NSSC has widened its supply-ability of duplex grades, and will expand its production capacity of plates next autumn by three times. Also, after completion of an under-going investment, NSSC will become the distinct supplier of duplex plates with the world’s widest width of 4M, which allows customers to make broad use of duplex stainless steel. In addition to four existing grades – ASTM S31803 and S32205, JIS SUS329J3L (NSSC®DX1) and SUS329J4L, NSSC has added three grades ASTM S32101 and S32304 (Lean Duplex) and S32750 (Super Duplex). ASTM S32101 can also be supplied as LDX2101®. After completion of the new pickling facility and cold leveler at its Yawata works by next September, the production capacity of duplex steel plates of NSSC will be 3000tns/mth which is three times the current volume. NSSC will also become capable of supplying 4M wide plate in duplex grades, instead of the current maximum availability of up to 3.2M. Currently NSSC has a size availability of duplex quarto plates with thickness of 6 to 60mm, maximum length and unit mass of 12M and 6.5tns respectively.
