Nucor Corp. announced that Nucor-Yamato Steel Company (NYS), a joint venture between Nucor and Yamato Kogyo Co. Ltd., is installing a $75 million quench and self-tempering (QST) process to be utilized on its 1.4 million tons of Mill 2 rolling capacity. The project at the company’s mill in Blytheville, Ark., is expected to be commissioned during the second half of 2016. The process will give NYS the ability to produce ASTM A913 Grade 65 and Grade 70 structural sections with a high-strength, low-alloy grade chemistry that provides excellent weldability while achieving good toughness at low temperatures. Common applications for the material will include gravity columns for use in high-rise buildings and long-span trusses for projects such as convention centers or stadiums.
