42crmo paipu kila ʻole
ʻO ka wehewehe pōkole:
Nā kikoʻī hana:
ʻO ke anawaena o waho o ka paipu kila 20-426
ʻO ka mānoanoa o ka paia paipu kila o 20-426
Hōʻike huahana:
ʻO ke kumu o 42crmo seamless steel paipu: ʻo ke kila kūikawā no ke alahaka ʻo "42crmo", ʻo ke kila kūikawā no ke kāʻei kaʻa ʻo "42CRmo", ʻo ke kila kūikawā no ka moku kaomi ʻo "42Crmo".ʻO kēia ʻano kila ke hilinaʻi nei i ka hoʻoponopono ʻana o ka ʻike kalapona (C) e hoʻomaikaʻi i nā ʻano mechanical o ke kila, no laila, e like me ka ʻike kalapona o ke kiʻekiʻe a me ka haʻahaʻa, hiki ke hoʻokaʻawale ʻia kēia ʻano kila i: haʻahaʻa carbon steel - carbon. ʻoi aku ka liʻiliʻi o ka ʻike ma mua o 0.25%, e like me 10, 20 kila, etc.;ʻO ke kila kalapona maʻamau - maʻamau ka maʻiʻo kalapona ma waena o 0.25 ~ 0.60%, e like me 35, 45 kila, a me nā mea ʻē aʻe.ʻAʻole hoʻohana maʻamau ia ʻano kila no ka hana ʻana i nā paipu kila.
Kaʻina hana kikoʻī:
