anuanu uila'ōwili hao DC01 DC03 DC04 DC06
Me ke kaha kiʻi maikaʻi ʻana a me ka hana kuʻihē a me ke kūpono kūpono kiʻekiʻe, ua ʻōwili ʻia ke koloka i ke kalapona haʻahaʻa a me nā papa kila kalapona ʻoi loa i hāʻawi ʻia e Mittel e pili nui i ka hana ʻana i nā ʻāpana kaʻa. Me kekahi ductility, DC04 (St14, St15) haʻahaʻa carbon a me ultra-low carbon automotive steel papa kūpono i ka maʻalahi hana ʻana, anuenue a kuʻihao paha.
DC04 (St14, St15) haʻahaʻa kalapona a me nā mīkini hana uila kalapona ʻoi loa-haʻahaʻa.
