Effects of Specimen Orientation on Tensile Properties of Rolled Steel Plates

Tensile properties in different specimen orientations (α=0°, 45°, 90°) had been tested among cold-rolled SPCC steel plate, hot-rolled SPHC steel plate, cold-rolled SUS304 stainless steel plate and hot-rolled SUS304 stainless steel plate with different thickness. Effects of specimen orientation on tensile properties of the rolled steel plates mentioned above were discussed, focusing on different level of tensile anisotropy induced by factors of specimen thickness, rolling state and steel material. The results indicate that specimen orientation has notable effects on tensile proerties of the rolled steel plates. Tensile strength and percentage elongation after fracture reach highest in rolling direction, while variation of yield strength is more complicated. Also, factors like specimen thickness, rolling state and steel material give different contribution to tensile anisotropy.
