Texture and stamping properties of SAF 2205 duplex stainless steel

The effects of cold rolling and annealing texture on the drawability of SAF 2205 duplex stainless steel were investigated. It is found that the deep drawability of SAF 2205 duplex stainless steel is poor with an average r value of 0.7 and the earing appears at 45° with a Δr value of -0.27,which is related with the texture formed during cold rolling and annealing. ODF results show that no γ fiber recrystallization texture forms in ferritic phase and the scattered α fiber texture still remains after annealing. Moreover,the ferritic texture exhibits a higher intensity than the austenitic one,thus it has more significant effect on the formability of the tested steel. It means that various components of the 〈110〉texture cause low average r values and make Δr<0. Furthermore,the {110}〈001〉texture of austenite exerts some effect on the formability of the sheet.
