ASTM A283 Pepa kila kalapona

Hōʻike ʻia ka ASTM A283 plate steel haʻahaʻa a me waena o ka ikaika tensile carbon steel plate of structural quality. Loaʻa iā ia nā ʻano like ʻole ʻehā, hōʻike ʻia kēlā me kēia ma ke ʻano he mea ʻokoʻa. Hōʻike ka ʻāpana waiwai ma lalo i nā pae e hoʻopuni ana i nā ʻano like ʻole.

Hoʻopili kēia kikoʻī i nā papa ʻehā o nā papa kila kalapona o ka maikaʻi o ke kūkulu ʻana no ka noi maʻamau. E hoʻoheheʻe ʻia nā laʻana kila e ka umu open-hearth, basic-oxygen, a i ʻole ka umu uila. E hoʻokō ʻia ka nānā ʻana i ka wela a me ka huahana kahi e kūlike ai nā mea kila me nā mea i makemake ʻia o ke kalapona, manganese, phosphorus, sulfur, silicon, a me ke keleawe. E ho'āʻo pū ʻia nā mea kila kila a e kūlike me nā waiwai i koi ʻia o ka ikaika tensile, kiko hua, a me ka elongation.
