Abstract Histrength IF steel(170P1) produced by two hot rolling processes(normal and hot rolling in ferrite area) was studied. The results indicate that rvalue of Histrength IF steel hot rolled in ferrites area is up to 2.1. The qualification rate of the wings fabricated from the sheets produced in this way reaches 100%.
