A Highly Engineered Process

In 2012, Nucor began expanding our engineered bar and wire rod production capabilities by approximately 1 million tons by investing in our Nebraska, South Carolina and Tennessee bar mills. Today we supply the most demanding engineered bar application markets, providing a full range of SBQ and wire rod products to all of our regional customers.

Our production process ensures that we can meet the most stringent standards our customers require. Teams of metallurgical engineers are on site and inspecting throughout the process to ensure the highest levels of quality. Depending on our customers’ engineered bar needs, we can employ vacuum degassing to: improve cleanliness by removing hydrogen, oxygen, and nitrogen; ensure steel is produced to uniform and close chemical specification ranges; enhance capability to produce low-carbon grades; and improve temperature control during continuous casting. After refining and alloying, our ladles are taken to the continuous caster, where the molten steel flows through a ceramic tube while being shrouded by argon gas to ensure cleanliness.

When strength, size and surface are essential, cold-finish processing may be required. We offer a wide variety of cold-finish options, which include cold drawing, turning, polishing, grinding, heat treating, stress relieving, annealing, quench and tempering, normalizing, high-speed saw blanking, surface testing and ultrasonic testing.

Our goal is to develop a deeper understanding of our customers’ business so we can increase the value we provide through customization. That’s why we offer additional value-added processes and services to our hot-roll and cold-finish products.
