No ka mea, ʻaʻole i hoʻopili ʻia, ua kiʻekiʻe loa kona paʻakikī (ʻoi aku ka nui o HRB ma mua o 90), a ʻilihune loa kona machinability, no laila hiki iā ia ke hana maʻalahi ke kulou ʻana ma lalo o 90 degere (perpendicular to the coiling direction).
No ka maʻalahi, ua hana ʻia ka ʻōwili anuanu a ʻōwili ʻia ma ke kumu o nā ʻōwili wela. ʻO ka ʻōlelo maʻamau, he hana ia o ka ʻōwili wela---pickling---ka ʻōwili anuanu.
Hana ʻia ʻo Cold-rolled mai nā ʻāpana wela i ka lumi wela. ʻOiai e hoʻomehanaʻia ka mahana o ka pepa kila i ka wā o ka hanaʻana, ua kapaʻiaʻo ia he cold-rolled. Ma muli o ka hoʻololi mau ʻana o ke anuanu o ka ʻōwili wela, ʻilihune nā waiwai mechanical a kiʻekiʻe loa ka paʻakikī. Pono e hoʻopili ʻia no ka hoʻihoʻi ʻana i kona mau waiwai mechanical, a ʻo ka poʻe me ka annealing ʻole i kapa ʻia nā ʻōwili paʻa. Hoʻohana mau ʻia nā ʻōwili paʻa paʻa no ka hana ʻana i nā huahana ʻaʻole pono ke kulou a hoʻolōʻihi ʻia, a ʻo nā mea me ka mānoanoa o lalo o 1.0 e ʻōwili ʻia ma nā ʻaoʻao ʻelua a i ʻole ʻehā ʻaoʻao me ka laki maikaʻi.
