Nippon Steel & Sumikin Stainless Corp. (NSSSC) says it has raised cold rolled stainless sheet prices for the thirteenth straight month because of higher nickel costs. NSSSC’s January contract price for March delivery of its Ni-based 304 series CR STS increased JPY 10,000t/y to JPY 545,000/t due to an increase in its alloy surcharge, the company said, adding the base price remains unchanged. It left January contract prices for Crbased 430 series CR sheet unchanged, following a JPY 10,000/t hike last month.
