ʻO nā kila Carbon kiʻekiʻe ʻO ka uwea paʻa ER70S-3 weld fabrication mea
He kūpono no ka paila, pahu kemika, mīkini, hana, hana moku a me nā ʻoihana ʻē aʻe, no nā koi kiʻekiʻe o ke kila kalapona haʻahaʻa a me ka hoʻoheheʻe ʻana i ke kila kila.
He aha nā hiʻohiʻona?
●Paʻa arc, nani hana, maikaʻi fluidity o ka hao heheʻe, maikaʻi māwae kū'ē, maikai kuʻihao kaʻina hana.
●He haʻahaʻa ka maʻiʻo o S a me P o ka metala hoʻoheheʻe ʻia, a he maikaʻi ka plasticity, ka paʻakikī o ka hopena a me ke kūpaʻa HIC/SSC.
