He aha ka mea SS400? He aha ka papa kila hale pili no SS400?

SS400he ipu hao kalapona maʻamau Iapana e like me JIS G3101. Ua like ia me Q235B i ka pae aupuni Kina, me ka ikaika tensile o 400 MPa. Ma muli o kāna ʻano kalapona haʻahaʻa, hāʻawi ʻo ia i nā waiwai piha i kaulike maikaʻi, e loaʻa ana ka hoʻohui maikaʻi ʻana ma waena o ka ikaika, ductility, a me ka weldability, e lilo ia i mea hoʻohana nui loa.
Nā ʻokoʻa ma waenaQ235b Ss400:

Nā Kūlana like ʻole:
Q235Bhahai i ka Chinese National Standard (GB/T700-2006). Hōʻike ka "Q" i ka ikaika o ka hoʻoulu ʻana, '235' hōʻike i ka ikaika haʻahaʻa haʻahaʻa o 235 MPa, a ʻo "B" ke ʻano o ka pae maikaʻi. Ua hahai ʻo SS400 i ka Japanese Industrial Standard (JIS G3101), kahi i hōʻike ai ʻo "SS" i ke kila kila a ʻo "400" e hōʻike ana i ka ikaika tensile ma mua o 400 MPa. I loko o 16mm kila kila specimens, SS400 hōʻike i ka hua ikaika 10 MPa kiʻekiʻe ma mua o Q235A. ʻOi aku ka ikaika o ka tensile a me ka elongation ma mua o ka Q235A.

 

Nā hiʻohiʻona hana:

Ma nā noi kūpono, hōʻike nā papa ʻelua i ka hana like a kūʻai pinepine ʻia a hana ʻia e like me ke kila kalapona maʻamau, me ka liʻiliʻi o nā ʻokoʻa. Eia nō naʻe, mai kahi hiʻohiʻona wehewehe maʻamau, hoʻoikaika ʻo Q235B i ka ikaika o ka hoʻoulu ʻana, aʻo SS400 ka mea nui i ka ikaika tensile. No nā papahana me nā koi kiko'ī no nā waiwai mechanical kila, pono ke kohoʻana i nā pono kiko'ī.

 

He ʻoi aku ka liʻiliʻi o nā papa kila Q235A ma mua o SS400. Ua like loa ka SS400 me ka Q235 o Kina (e like me ka hoohana Q235A). Eia naʻe, ʻokoʻa nā hōʻailona kikoʻī: Hōʻike ʻo Q235 i nā palena maʻiʻo no nā mea e like me C, Si, Mn, S, a me P, aʻo SS400 wale nō ke koi iā S a me P e emi iho ma mua o 0.050. Loaʻa i ka Q235 ka ikaika hua ma mua o 235 MPa, aʻo SS400 ka loaʻa ʻana o 245 MPa. ʻO SS400 (ka kila no ka hana maʻamau) e hōʻike ana i ke kila hana maʻamau me ka ikaika tensile ma mua o 400 MPa. Hōʻike ka Q235 i ke kila kalapona maʻamau me ka ikaika o ka hoʻoulu ʻana ma mua o 235 MPa.

 

Hoʻohana ʻia o SS400: ʻO ka SS400 ka mea maʻamau i ʻōwili ʻia i loko o nā koʻokoʻo uea, nā kaola poepoe, nā kī kīhaʻi, nā kaola palahalaha, nā ʻāpana kihi, nā I-beams, nā ʻāpana channel, nā kila puka aniani, a me nā ʻano hana ʻē aʻe, a me nā papa waena-mānoanoa. Hoʻohana nui ʻia i nā alahaka, nā moku, nā kaʻa, nā hale, a me nā hale ʻenekinia. Hoʻohana ʻia ʻo ia ma ke ʻano he hoʻoikaika paʻa a i ʻole ke kūkulu ʻana i nā hale hale hale hana, nā hale kiaʻi hoʻoili uila kiʻekiʻe, nā alahaka, nā kaʻa, nā paila, nā ipu, nā moku, a me nā mea ʻē aʻe. Hiki ke hoʻohana ʻia nā kila C a me D no kekahi mau noi kūikawā.
