1.Hot rolled steel strip ua'ōwiliʻia i ke kiʻekiʻe wela a he maikaʻi ka ductility.
2.Hot'ōwili kila kaula hiki i ka mānoanoa nui.
3. ʻOi aku ka ʻoi aku o ka paʻakikī o ka ʻōwili kila wela.
4. 'Oko'a ma waena o ka wela olokaa a me ke anu i olokaa kila kaula:
He haʻahaʻa haʻahaʻa koʻikoʻi ka paʻakikī paʻakikī ma muli o ke ʻano o ka paʻakikī o ka hana, akā hiki ke hoʻokō i kahi lākiō hua maikaʻi, a hiki ke hoʻohana ʻia no nā ʻāpana puna a me nā ʻāpana ʻē aʻe.I ka manawa like, no ka mea kokoke i ka ikaika tensile, ʻaʻohe ʻike no ka pōʻino i ka wā o ka hoʻohana ʻana, a maʻalahi nā pōʻino i ka wā i ʻoi aku ai ka ukana ma mua o ka ukana i ʻae ʻia.
1) ʻO ka pā anu i ʻōwili ʻia a ʻaʻohe unahi ma luna o kona ʻili a me ka maikaʻi maikaʻi.ʻO nā pā kila wela i ʻōwili ʻia, me ka unahi ma ka ʻili a me ka ʻokoʻa o ka mānoanoa.
2) Loaʻa ka ʻilihune ʻino a me ka maʻalahi o ka ʻili, a ʻoi aku ka haʻahaʻa o kāna kumukūʻai, ʻoiai ʻoi aku ka maikaʻi o ka hoʻonui a me ka paʻakikī, akā ʻoi aku ka kiʻekiʻe o ke kumukūʻai.
3) Hoʻokaʻawale ʻia ka ʻōwili kila i ka ʻōwili anu a me ka ʻōwili wela, me ka mahana recrystallization e like me ke ʻano ʻokoʻa.
4) ʻO ka ʻōwili anu: Hoʻohana maʻamau ka ʻōwili anuanu e hana i ke kaula me ka wikiwiki o ka ʻōwili kiʻekiʻe.ʻO ke kila ʻōwili wela: wela ka wela a me ka wela forging
5) He ʻeleʻele ʻeleʻele ʻeleʻele ka ʻili o ke kila i ʻōwili ʻia me ka ʻole o ka electroplating, ʻoiai ʻo ka mea o ke kila i ʻōwili ʻia me ka ʻole o ka electroplating he hina, hiki ke hoʻokaʻawale ʻia mai ka maʻalahi o ka ʻili ma hope o ka electroplating, a ʻoi aku ka maikaʻi o ka maʻemaʻe o ke kila i ʻōwili ʻia ma mua o ʻo ke kila ʻōwili wela.
