Overview

Nucor and Yamato Kogyo formed the joint venture in 1987 to run a mini-mill making wide-flange beams, and the plant opened in the Armorel area in 1988. It now makes wide-flange beams, H-piling, sheet piling, standard I-beams and channels, with more than 2.5 million tons a year of capacity and more than 800 employees.

Profile

Quench and self-tempering on Mill 2
In 2015 Nucor announced a $75 million quench and self-tempering process for the 1.4 million tons of Mill 2 rolling capacity, to be commissioned in the second half of 2016. It lets the mill make ASTM A913 Grade 65 and 70 high-strength sections.
Power in a steel county
Mississippi County is served by both Entergy Arkansas and the member-owned Mississippi County Electric Cooperative, and the county's development office quotes industrial power rates of 4 to 6 cents per kWh. Nucor runs three other plants in the area making sheet, thin-cast sheet and pipe. Big River Steel sits nearby on land once owned by Entergy Arkansas. The serving utility for Nucor-Yamato itself is not stated in these sources.
