Traditional mechanical property tests for ultimate and yield strenghts, reduction in area, elongation, impact, and the nil-ductility temperature were peformed on AAR TC128 grade B steel in the normalized, and the normalized and stress relieved conditions from -51 C to room temperature. In addition, the crack initiation fracture toughness, as a function of temperature, was determined using crack tip opening displacment (CTOD) and J integral test procedures. The crack arrest fracture toughness, as a function of temperature, was also determined. It was found that the normalized and stress relieved steel had overall better mechanical, impact, and fracture toughness properties than the normalized steel.
