ʻO ka pahu hao kihi SS400 JIS
I ke kūʻai ʻana a me ka hoʻohana ʻana i kēia ʻano kihi kihi, he mea nui e hoʻomaopopo i kona ʻano waiwai a me nā kikoʻī.
Hoʻohui Kimia
ʻO ka hui kemika o ka SS400 steel angle bar pono e hoʻokō i nā lula o JIS G 3112. ʻO kāna mau mea nui he hao (Fe), carbon (C), silicon (Si), manganese (Mn) a me nā mea ʻē aʻe.Ma waena o lākou, pono ka ʻike kalapona ma waena o 0.18% -0.28%, ʻo ka ʻike silika ma waena o 0.12% -0.30%, a ʻo ka manganese ma waena o 0.70% -1.00%.Eia kekahi, pono e loaʻa i ke kila kihi kekahi mau mea o ka phosphorus (P) a me ka sulfur (S) e hoʻonui ai i kona paʻakikī a me ka ikaika.
Pono nā mea mechanical o ka SS400 profile steel e hoʻokō i nā lula o JIS G 3112. ʻAʻole pono kona ikaika tensile (σb) ma lalo o 400N/mm², a ʻo kona ikaika hua (σs) ʻaʻole pono e emi iho ma mua o 240N/mm².I ka manawa like, ʻaʻole pono e emi iho ka elongation (δ) o ka pahu kihi kila wela ma lalo o 22%.Ke hōʻoia nei kēia mau mea mechanical i ka SS400 angle steel he kiʻekiʻe ka haʻahaʻa haʻahaʻa a me ka lōʻihi i nā hiʻohiʻona noi.
Na Waiwai Mechanical
Hana hana
He maikaʻi ka hana kaʻina hana SS400 a hiki ke hoʻohana ʻia no ke kuʻo ʻana, hoʻopololei, ʻāhi, hoʻopaʻa ʻana a me nā hana hana ʻē aʻe.I ka manawa like, loaʻa i kēia ʻano ʻano o ka welding steel profiles maikaʻi a hiki ke hoʻokō i nā koi wili like ʻole.I ka wā o ka hana ʻana, pono e uku ʻia ka nānā ʻana i ka mālama ʻana i ka mahana a me ka nui o ka hoʻoilo e pale aku i nā māwae a me ka deformation o ke kila kihi.
Pale ʻino
SS400 kihi kila i kekahi corrosion kū'ē, akā, ua prone i ka pala i loko o humid kaiapuni.I mea e hoʻomaikaʻi ai i kona pale ʻana i ka corrosion, hiki ke uhi ʻia ka ʻili o ke kila kihi me kahi papa o ka pena anti-rust.Eia kekahi, i ka wā o ka lawe ʻana a me ka mālama ʻana, pono e mālama ʻia ke kila kihi e maloʻo a maʻemaʻe e pale i ka ʻike lōʻihi i ka wai.
I ka pōkole, ʻo ke kila ʻoki maʻamau ʻo Iapana SS400 he kila kiʻekiʻe kiʻekiʻe i hoʻohana nui ʻia i nā hana like ʻole, nā alahaka, nā moku, nā kaʻa a me nā māla ʻē aʻe.He mea nui e hoʻomaopopo i kona mau waiwai waiwai a me nā kikoʻī i ka wā e kūʻai ai a hoʻohana i kēia ʻano kila angle.I ka wā o ka hoʻohana ʻana, pono e nānā i ka mālama ʻana a me ka mālama ʻana e hōʻoia i kona palekana a me ke ola lawelawe.
