North American Stainless (NAS) and its parent company, Acerinox, will invest approximately $150 million to expand its manufacturing facility in Ghent, Ky. The company plans to add a bright annealing line and a cold-rolling mill. The bright annealing line will process material from the rolling mill after degreasing the surface of the strip and heat treating it in a controlled atmosphere, giving the material a bright finish. The expansion, which will create 36 new jobs, is the company’s 11th since it began operations in Kentucky in 1990. It is expected to be complete by 2017.
