Hot Rolled Flat Steel Origin in Kina kila palahalaha nā huahana ʻē aʻe kuhiliʻole bar paʻa kila

304 kuhiliʻole kila palahalaha rust pale kiʻiʻoniʻoni, i mea e pale aku ai i ke kila pono'ī e ke kaiapuni o waho o ka ea (ʻoi aku ka oxygen), ka wai, kekahi waikawa, alkali oxidation corrosion.

ʻO ke kila kila honua, hoʻohana nui ʻia i ka hana ʻana i nā mea hana a me nā ʻāpana e koi ana i kahi hui maikaʻi o nā waiwai (corrosion resistance and formability).Hiki ke pale i ka ʻino maʻamau i loko o ka hale, hiki ke pale i ka ʻānai ʻana o ka media hoʻoponopono meaʻai (akā, aia nā ʻāpana koʻikoʻi a me nā ʻāpana chloride hiki ke corrosion i nā wela kiʻekiʻe), hiki ke pale aku i nā pūhui organik, nā mea pena a me nā ʻano mea like ʻole.ʻAno 304L (carbon haʻahaʻa), kūʻē maikaʻi i ka waikawa nitric, a me ka mahana wela a me ka neʻe ʻana o ka sulfuric acid, hoʻohana nui ʻia e like me ka pahu mālama kinoea wai, hoʻohana ʻia i nā lako cryogenic (304N), nā mea hana a me nā huahana mea kūʻai aku, nā lako kīhini, nā lako halemai. , ka lawe ʻana, nā mea hana wai ʻino.ʻO 304 he kila kuhili honua, i hoʻohana nui ʻia i ka hana ʻana i nā mea hana a me nā ʻāpana e koi ana i nā waiwai piha maikaʻi (ke kūpaʻa corrosion a me ka formability).Hōʻike ʻo 301 stainless steel i ka paʻakikī o ka hana i ka wā deformation, i hoʻohana ʻia i nā manawa like ʻole e koi ana i ka ikaika kiʻekiʻe.ʻO 304 stainless steel flat steel he ʻano like ʻole o 304 stainless steel me ka ʻike kalapona kiʻekiʻe, hiki ke loaʻa ka ikaika kiʻekiʻe ma o ka ʻōwili anu.

ʻO 304L kahi ʻano like ʻole o 304 stainless steel me ka haʻahaʻa carbon content a hoʻohana ʻia no nā noi wili.ʻO ka haʻahaʻa kalapona maʻiʻo ka hopena i ka liʻiliʻi o nā carbides i hoʻoheheʻe ʻia i loko o ka wahi i hoʻopilikia ʻia ma kahi kokoke i ka weld, hiki ke alakaʻi i ka ʻino intergranular (welding erosion) o ke kila kila ma kekahi mau kaiapuni.ʻO 304N he kila kila i loaʻa ka nitrogen, hoʻohui ʻia ka nitrogen e hoʻomaikaʻi i ka ikaika o ke kila.Loaʻa i ka 304 stainless steel flat steel kiʻekiʻe ka nickel, ʻoi aku ka haʻahaʻa o kāna hana paʻakikī, kūpono i nā koi hoʻokumu anuanu o nā manawa like ʻole.
