THE MECHANICAL PROPERTY OF BATCH ANNEALED HIGH STRENGTH LOW ALLOY STEEL HC260LA
Cold rolled high strength low alloy steel is widely applied in the automotive parts due to its excellent formability and weldability.In this paper,the steel grade HC260LA according to European Norm was developed with batch annealing process.With commercial C-Mn mild steel as a benchmark,three different groups of chemistry namely C-Mn-Si,C-Mn-Nb-Ti and C-Mn-Nb were compared in terms of yield-tensile strength(Y/T)ratio.Microstructure and mechanical properties were characterized as well.Based on industrial production results,chemistry and detailed process parameters for batch annealing were identified.In the end the optimal Y/T ratio was proposed for this steel grade under batch annealing process.
