The influence of up to 50% deformation by single-pass rolling at the intercritical annealing temperature of 1053-1113 K on the structure and mechanical properties of a commercial-grade, plain, low-carbon AISI 1010 steel has been studied. The optimum thermomechanical treatment was found to consist of deformation to 50% after a 10 min anneal at 1083 K, followed by a rapid quench in iced brine. The yield strength and UTS were 575 and 690 M N m−2, respectively, while the uniform elongation was 14%. The structures of specimens treated in various ways have been studied, and an attempt has been made to correlate these structures with the mechanical properties.
