42CRMO Paipu kila maʻemaʻe ʻole
ʻO ke kumu o 42crmo seamless steel pipe: ʻO ke kila kila kūikawā no nā alahaka ʻo "42crmo", ʻo ke kila kila kūikawā no nā kāʻei kaʻa ʻo "42CRmo", a ʻo ka māka kila kūikawā no nā moku kaomi ʻo "42Crmo".Ke hilinaʻi nei kēia ʻano kila i ka hoʻoponopono ʻana i ka maʻiʻo kalapona (C) e hoʻomaikaʻi i nā ʻano mechanical o ke kila.No laila, e like me ke kiʻekiʻe o ka maʻiʻo kalapona, hiki ke hoʻokaʻawale ʻia kēia ʻano kila i: ʻO ke kila kalapona haʻahaʻa-ʻo ka maʻi kalapona ma lalo o 0.25%, e like me 10, 20 kila, etc.;ʻO ka maʻamau kalapona kalapona ma waena o 0.25 a me 0.60%, e like me 35, 45 kila, etc.;ʻoi aku ka nui o ka maʻiʻo kalapona kiʻekiʻe ma mua o 0.60%.ʻAʻole hoʻohana ʻia kēia ʻano kila i ka hana ʻana i nā paipu kila.
ʻAʻole ʻike ʻia ka palupalu o ka huhū, ka liʻiliʻi liʻiliʻi i ka wā e hoʻopio ai, ka palena luhi nui a me ka pale ʻana i nā hopena he nui ma hope o ka hoʻopau ʻana a me ka hoʻomaʻamaʻa ʻana, maikaʻi ka hopena haʻahaʻa haʻahaʻa haʻahaʻa, ikaika kolo kiʻekiʻe a me ka ikaika mau i ka wela kiʻekiʻe.Hoʻohana maʻamau ke kila i ka hoʻopau ʻana i ka ʻili ma hope o ka hoʻopiʻi ʻana a me ka hoʻomaʻamaʻa ʻana e like me ka hoʻolālā mālama wela.
ʻO 42crmo kahi mea i ke kila.I ka wā ma mua, he inoa no ke kila.ʻO ka inoa: Q345B, nā mea like he Q345a, Q345c, Q345e, ʻo ka hōʻailona papa maikaʻi ʻo ABCDE ʻo ia ka mea ʻaʻole koi ʻia ka mahana hoʻokolohua hopena i +20 degere 0 degere -20 degere 40 degere ʻo ABCD e hōʻike ana i ka pae kiʻekiʻe Q235 pae kiʻekiʻe. ʻEhā pae o A, B, C, D, mai A a i D mai ka haʻahaʻa a i ke kiʻekiʻe.
ʻO nā koi no nā pae maikaʻi like ʻole penei:
A——E hāʻawi i ka haku mele ʻana o S, P, C, Mn, Si a me fu, fy, δ5 (δ10), e like me ka makemake o ka mea kūʻai aku, hiki ke hāʻawi ʻia i ka hoʻāʻo ʻana i ke anu anuanu 1800, akā ʻaʻohe hopena o ka ikehu hoʻoponopono, carbon ʻAʻole manaʻo ʻia ka ʻike a me ka manganese i nā kūlana lawe.
B——E hoʻolako iā S, P, C, Mn, Si hoʻohui kemika a me ka fu, fy, δ5 (δ10), hoʻāʻo 180' anu anuanu.Hāʻawi pū ia i ka ikehu hopena ma +200C, Ak≥27J
C-Ma waho aʻe o nā koi like me ka Papa B, hāʻawi pū ia i ka ikehu hopena Ak≥27J ma 00C.
D----Ma waho aʻe o nā koi o ka pae B, hāʻawi pū ia i ka ikehu hopena Ak≥27J ma -200C.E----Ma waho aʻe o nā koi o ka pae B, hāʻawi pū ia i ka ikehu hopena Ak≥27J ma -400C.
Ma kahi o 42crmo paipu kila maʻemaʻe a me nā paipu kila maʻamau e pili ana i kēlā me kēia: Ua māhele ʻia nā paipu kila i ka huki anu a me ka ʻōwili wela.
