Kūʻai palapala hōʻoia o 30CrMo ka mea hana paipu kila
ʻO 16Mn kahi kila haʻahaʻa haʻahaʻa haʻahaʻa ikaika: ʻo ka maʻi kalapona he 0.1% - 0.25%, a ua hoʻohui ʻia nā mea hao nui manganese, silicon, vanadium, niobium a me titanium; ʻO ka nui o kāna mau mea i hoʻohuihui ʻia ma lalo o 3%. Wahi a ka ikaika, ua māhele ʻia i ʻehā mau pae: 300, 350, 400 a me 450MPa. Aia ka nui o q295, Q345, Q390, Q420 a me Q460 "Q" ʻo ia ka Chinese Pinyin capital prefix o ka huaʻōlelo "Qu" e hāʻawi mai, a ʻo ka helu ma hope ka helu liʻiliʻi loa o ka brand (σ s) ʻO nā hōʻailona hope. mahele i ka a, B, C a me d e like me ka maʻiʻo o nā mea haumia (sulfur a me ka phosphorus) i ke kila mai kiʻekiʻe a haʻahaʻa a me ka hoʻololi o ke kalapona a me ka manganese. Ma waena o lākou, kapa ʻia nā kila A a me B he 16Mn.
Wahi a ka ikaika, ua māhele ʻia i ʻehā mau pae: 300, 350, 400 a me 450MPa.
Aia ka nui q295, Q345, Q390, Q420 a me Q460.

ʻO 16Mn paipu kila ʻole he ʻano mea. Ua kapa 'ia ka paipu kila 'ole.
ʻO ke ʻano o kēia manawa: Q345B paipu kila ʻole. ʻO nā mea like me Q345C, Q345D a me Q345E. Hōʻike ka hōʻailona papa maikaʻi a, B, C, de i nā koi like ʻole no ka hoʻāʻo hopena. ʻO ka mahana ho'āʻo hopena he + 20 ° 0 ° a 20 ° 40 ° pakahi. ʻO 16Mn kahi mea o ka paipu kila ʻole.
Hōʻike ka ABCD i ka helu Q235 maikaʻi. Hoʻokaʻawale ʻia ka papa maikaʻi i ʻehā mau papa A, B, C a me D. mai a a i D e hōʻike ana i ka maikaʻi mai ka haʻahaʻa a i ke kiʻekiʻe.
ʻO nā koi no nā pae maikaʻi like ʻole penei:
A - hāʻawi s, P, C, Mn, Si chemical haku mele 'ana a me Fu, FY δ 5（ δ 10), 1800 anu ho'āʻo kulou hiki ke hoʻolako e like me ka mea kūʻai mai e pono ai, akā,ʻaʻohe hopena ikehu hooponopono, a me ka carbon maʻiʻo. ʻAʻole lawe ʻia ka ʻike manganese ma ke ʻano o ka lawe ʻana.
B - hāʻawi s, P, C, Mn, Si chemical haku mele a me Fu, FY δ 5（ δ 10) , anu 180 ' hoao. Hāʻawi pū ia i ka ikehu hopena AK ≥ 27j ma + 200C - ma waho aʻe o nā koi o ka papa B, hāʻawi pū ia i ka ikehu hopena AK ≥ 27j ma 00C.
C - ma waho aʻe o nā koi o ka pae B, hāʻawi pū ʻia ka ikehu hopena AK ≥ 27j ma - 200C. E - ma waho aʻe o nā koi o ka pae B, hāʻawi pū ʻia ka ikehu hopena AK ≥ 27j ma - 400C.
