Nānā nui o ka Cold Rolled Steel Coil
Hana ʻia ka ʻōwili anuanu me ka ʻōwili wela wela. Ma ke kaʻina hana ʻōwili anu, ʻōwili ʻia ka ʻōwili wela ma lalo o ka mahana recrystallization, a ʻōwili ʻia ke kila i ʻōwili ʻia ma ka lumi wela. He haʻahaʻa haʻahaʻa ka haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa ka pepa kila me ka ʻike silika kiʻekiʻe, a pono e hoʻomehana ʻia i 200 °C ma mua o ka ʻōwili ʻana. No ka mea, ʻaʻole i hoʻomehana ʻia ka coil i ʻōwili ʻia i ka wā o ke kaʻina hana, ʻaʻohe hemahema e like me ka pitting a me ka hao oxide i ʻike pinepine ʻia i ka ʻōwili wela, a maikaʻi ka maikaʻi o ka ʻili a me ka hopena.
