Cold forming low carbon steel

Note

       a) tensile test here means for transverse sample with width b=25mm, L0=50mm.

      b) when no obvious yield point, Rel can be replaced with Rp0.2.  when product thickness <0.70mm and ≥0.50mm, upper limit of yield strength can be added by 20N/mm2, while thickness <0.50mm can add 40 N/mm2;

     c) when product thickness<1.50mm and ≤2.0mm, value r90 or r can decrease by 0.1 (absolute value). while>2.0mm then decrease 0.2 (absolute value);

 d) r90 & n90 or r& n only suitable for product with thickness ≥0.50mm.  r=(r0+ r45+ r90)/4, n=(n0+ n45+ n90)/4.
