He aha ka mea SS400? He aha ke ʻano kila kūloko kūpono no SS400?

SS400He papa kila hoʻonohonoho kalapona maʻamau Kepani e kūlike ana me JIS G3101. Hoʻohālikelike ia me Q235B ma ke kūlana aupuni Kina, me ka ikaika tensile o 400 MPa. Ma muli o kona ʻano kalapona kūpono, hāʻawi ia i nā waiwai piha kaulike maikaʻi, e hoʻokō ana i ka hoʻohui maikaʻi ma waena o ka ikaika, ka ductility, a me ka weldability, e lilo ia i papa i hoʻohana nui ʻia.
Nā ʻokoʻa ma waenaQ235b Ss400:

Nā Kūlana like ʻole:
Q235BUa hahai ʻo "Q" i ka ikaika hua, ʻo "235" ke kuhikuhi nei i ka ikaika hua liʻiliʻi loa o 235 MPa, a ʻo "B" ke kuhikuhi nei i ka pae maikaʻi. Ua hahai ʻo SS400 i ka Japanese Industrial Standard (JIS G3101), kahi e hōʻike ai ʻo "SS" i ke kila kūkulu a ʻo "400" ke kuhikuhi nei i ka ikaika tensile e ʻoi aku ana ma mua o 400 MPa. Ma nā ʻano papa kila 16mm, hōʻike ʻo SS400 i ka ikaika hua 10 MPa ʻoi aku ka kiʻekiʻe ma mua o Q235A. ʻOi aku ka ikaika tensile a me ka elongation ma mua o Q235A.

 

Nā ʻano hana:

Ma nā noi hana, hōʻike nā papa ʻelua i ka hana like a kūʻai pinepine ʻia a hana ʻia e like me ke kila kalapona maʻamau, me nā ʻokoʻa i ʻike nui ʻole ʻia. Eia nō naʻe, mai kahi hiʻohiʻona wehewehe maʻamau, hoʻoikaika ʻo Q235B i ka ikaika hua, ʻoiai ʻo SS400 e hoʻoikaika i ka ikaika tensile. No nā papahana me nā koi kikoʻī no nā waiwai mechanical kila, pono ke koho ʻana ma muli o nā pono kikoʻī.

 

ʻOi aku ka haiki o ka laulā noi o nā papa kila Q235A ma mua o SS400. Ua like loa ʻo SS400 me ka Q235 o Kina (like me ka hoʻohana ʻana o Q235A). Eia nō naʻe, ʻokoʻa nā ʻano kikoʻī: Kuhikuhi ʻo Q235 i nā palena o ka ʻike no nā mea e like me C, Si, Mn, S, a me P, ʻoiai ʻo SS400 e koi wale ana iā S a me P e emi ma mua o 0.050. ʻOi aku ka ikaika o ka Q235 ma mua o 235 MPa, ʻoiai ʻo SS400 e hoʻokō i 245 MPa. Hōʻike ʻo SS400 (kila no ka hoʻonohonoho maʻamau) i ke kila hoʻonohonoho maʻamau me ka ikaika tensile ma mua o 400 MPa. Hōʻike ʻo Q235 i ke kila hoʻonohonoho kalapona maʻamau me ka ikaika o ka hoʻonohonoho ma mua o 235 MPa.

 

Nā Hoʻohana o SS400: Hoʻopili pinepine ʻia ʻo SS400 i loko o nā koʻokoʻo uea, nā kaola poepoe, nā kaola huinaha, nā kaola pālahalaha, nā kaola kihi, nā kaola I, nā ʻāpana kahawai, ke kila kila puka makani, a me nā ʻano kūkulu ʻē aʻe, a me nā papa mānoanoa waena. Hoʻohana nui ʻia ia i nā alahaka, nā moku, nā kaʻa, nā hale, a me nā ʻano hana ʻenekinia. Hana ia ma ke ʻano he mau kaola hoʻoikaika a i ʻole no ke kūkulu ʻana i nā trusses hale hana, nā hale kiaʻi hoʻoili uila kiʻekiʻe, nā alahaka, nā kaʻa, nā paila, nā ipu, nā moku, a pēlā aku. Hoʻohana nui ʻia no nā ʻāpana mīkini me nā koi hana ʻoi aku ka paʻakikī. Hiki ke hoʻohana ʻia nā kila Papa C a me D no kekahi mau noi kūikawā.
