Ka wehewehe ʻana i ka haku mele a me ke kaʻina hana hana o nā paipu kila kalapona

ʻO ka Paipu Kila Kalapona he paipu i hana ʻia me ke kila kalapona ma ke ʻano he mea nui. ʻO kona nui kalapona ma waena o 0.06% a me 1.5%, a loaʻa iā ia kahi liʻiliʻi o ka manganese, silicon, sulfur, phosphorus a me nā mea ʻē aʻe. Wahi a nā kūlana honua (e like me ASTM, GB), hiki ke hoʻokaʻawale ʻia nā paipu kila kalapona i ʻekolu mau māhele: kila kalapona haʻahaʻa (C≤0.25%), kila kalapona waena (C=0.25%~0.60%) a me ke kila kalapona kiʻekiʻe (C≥0.60%). I waena o lākou, ʻo nā paipu kila kalapona haʻahaʻa ka mea i hoʻohana nui ʻia ma muli o ko lākou hiki ke hana maikaʻi a me ka hiki ke hoʻopili ʻia.
