Description
Improvements in mechanical property performance often result in higher production cost. Recent process metallurgy technology is applied in wire products to address this demand. The process influence is now balanced with improved wire rod microstructure, properties, and grain size consistency. The complementary benefit of micro-additions of niobium refines the microstructure, reduces scrap, and improves drawability and robustness. Case examples involve pre-stressed concrete wire rod, tire cord, and medium carbon spring steels.
