ʻO SS400 kahi papa kila kalapona maʻamau Kepanī, e hoʻokō ana i ka maʻamau JIS G3101, e like me Q235B ma ke kūlana aupuni.Ua like ia me ka maʻamau o Kina Q235B, me ka ikaika tensile o 400MPa.Ma muli o kona ʻano kalapona haʻahaʻa, he maikaʻi kāna hana holoʻokoʻa, a ua hoʻohālikelike ʻia kona ikaika, plasticity a me nā waiwai welding, e hoʻohana nui ʻia.

Hoʻopili pinepine ʻia ʻo SS400 i loko o kahi coil a i ʻole ke kila poepoe,ss4oo pepa kila wiliwili wela, kila huinaha, kila pālahalaha,ʻākoki kila ss4oo, I-beam, ke kila auwai, ke kila kila a me nā mea kila ʻē aʻe, a me ka pā kila mānoanoa.ʻO ka nui o nā noi i ke kūkulu ʻana a me nā hale ʻenekinia.Hoʻohana ʻia e hana i ka hoʻoikaika ʻana i ke kila a i ʻole ke kūkulu ʻana i nā mea kanu a me nā papa, nā hale kiaʻi uila kiʻekiʻe, nā alahaka, nā kaʻa, nā paila, nā ipu, nā moku, a me nā mea ʻē aʻe, hoʻohana ʻia e like me ka nui o nā koi hana ʻaʻole kiʻekiʻe loa nā ʻāpana mechanical;Hiki ke hoʻohana ʻia ke kila C, D-grade no kekahi kila kūikawā.
1, I loko o kahi hōʻailona pā kila 16mm, ʻo ka ikaika hua o ka pā kila SS400 he 10Mpa kiʻekiʻe ma mua o ka ikaika hua Q235A.
2, ʻOi aku ka ikaika o ka tensile a me ka elongation ma mua o Q235A.
3, He kūpono ka pā kila SS400 no nā alahaka, nā moku, a me nā kaʻa, ʻoi aku ka liʻiliʻi o ka pā kila Q235A ma mua o ka SS400.
Pono ka pā kila SS400 i nā ʻano hana kiʻekiʻe kiʻekiʻe, i ka hoʻohana ʻana i ke kaʻina hana he koʻikoʻi nō hoʻi, no laila, ʻo ka hapa nui o nā mea hoʻohana i hoʻomaikaʻi like ʻia a ʻike ʻia i ka ʻoihana hana, hoʻomau ka hoʻohana pinepine ʻana a me ka hoʻomaikaʻi ʻana. a ua lilo ka pā kila SS400 i kekahi o nā papa kila maʻamau i hoʻohana ʻia ma ka ʻāina.
