The mechanical and the low cycle fatigue (LCF) properties of cold-drawn AISI 1018 steel (CDS 1018) with and without hot-dip aluminizing (HDA) coating had been experimentally investigated at room temperature. The tensile properties and the LCF properties were determined from tensile test results and cyclic strain-fatigue test results, respectively. The aluminide coating on the CDS 1018 significantly decreases the mechanical properties and the strain-fatigue life of the steel. With increasing in strain amplitude levels, CDS 1018 experienced continuously cyclic softening behaviour after cyclic loading in few cycles. By contrast, the cyclic softening of HDA steel was observed in few cycles and HDA steel continuously exhibits the stably cyclic hardening behaviour until failure. CDS 1018 with aluminide coating results the longer transition fatigue cycles (N t ) than those of CDS 1018 without aluminide coating by a factor of ∼3.0. CDS 1018 with HDA coating can be used for material components which the components are safely designed under cyclic loading below the yield strength of the material.
