Nucor Announces Addition of QST Process at Arkansas Mill

An inside look at the steelmaking process at the Nucor-Yamato Steel (NYS) mill in Blytheville, Ark. Read more about their operation in our February 2014 article “Keep on Rolling.” 

Nucor Corporation (an AISC Member) has 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 used on its 1.4 million tons of Mill 2 rolling capacity. Nucor Chairman, CEO and President John Ferriola was joined by Arkansas Governor Asa Hutchinson to make the announcement last Friday at the Nucor-Yamato Steel mill in Blytheville, Ark. The project is expected to be commissioned during the second half of 2016.

Upon completion, 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.

“This strategic investment will keep Nucor-Yamato Steel the market leader in the wide-flange beam market servicing our customers across the United States,” said Ferriola. “The A913 market is a strategic part of the future of our company and will ensure we continue to meet and exceed our customers’ needs and requirements. Additionally, this investment will enable Nucor-Yamato, its more than 900 teammates and families and supply chain to remain a vibrant part of Northeast Arkansas today and well into the future.”

Common applications for the material will include gravity columns for use in high-rise buildings, long-span trusses for projects such as convention centers and stadiums and any projects where seismic design is a critical factor. The higher strength achieved from A913 will allow lighter foot weights to be specified, thus reducing overall weight and material costs.

“We are excited that Nucor is making this significant investment here in Arkansas,” said Governor Hutchinson. “Nucor has been an important part of Arkansas’ economy for almost three decades and this investment shows their continued commitment to our state.”
