ASTM A36 Pā kila

Ma muli o ka nui o ke kalapona i loko o ka huila. ʻO nā kila kalapona haʻahaʻa he palupalu a maʻalahi hoʻi, a ʻoi aku ka paʻakikī a me ka ikaika o nā kila me kahi kiʻekiʻe o ke kalapona, akā liʻiliʻi ka ductile, a lilo lākou i mea paʻakikī i ka mīkini a me ka weld. Aia ma lalo iho nā waiwai o nā māka o ke kila kalapona a mākou e hāʻawi nei:
● Haʻahaʻa Carbon Steel–Composition o 0.05% -0.25% carbon a hiki i ka 0.4% manganese. ʻIke ʻia hoʻi ʻo ke kila māmā, he mea kūʻai haʻahaʻa a maʻalahi ke hana. ʻOiai ʻaʻole paʻakikī e like me nā kila kalapona kiʻekiʻe, hiki i ke kanu ʻana i ke kaʻa ke hoʻonui i ka paʻakikī o ka ʻili.
● Medium Carbon Steel - Hoʻohui o 0.29% -0.54% carbon, me 0.60% -1.65% manganese. He ductile a ikaika ke kila kalapona waena, me nā waiwai lōʻihi.
● ʻO ke kila kalapona kiʻekiʻe– Ka hui ʻana o 0.55% -0.95% carbon, me 0.30% -0.90% manganese. He ikaika loa a paʻa maikaʻi ka hoʻomanaʻo ʻana i ke ʻano, kūpono ia no nā pūnāwai a me ka uea.
● ʻO ke kila kalapona kiʻekiʻe loa - ka hui ʻana o 0.96% -2.1% carbon. ʻO kona ʻano kalapona kiʻekiʻe e lilo ia i mea ikaika loa. Ma muli o kona palupalu, pono kēia māka i ka lawelawe kūikawā.
