I-Dachang yokwenene ye-304L yeentengiso zemibhobho yensimbi engenasici
I-American Iron and Steel Institute isebenzisa amanani amathathu ukuphawula imigangatho eyahlukeneyo
I-Quasi ithambileyo. Ngokuba:
① I-Austenitic steel stainless iboniswa ngamanani angama-200 kunye ne-300 series,
②Iintsimbi ze-Ferritic kunye ne-martensitic zimelwe ngamanani angama-400. Ngokomzekelo, ezinye zeentsimbi ze-austenitic eziqhelekileyo eziqhelekileyo
Iphawulwe 201, 304L, 316 kunye ne-310,
③ I-Ferritic steel stainless iphawulwe nge-430 kunye ne-446, kunye ne-martensitic steel stainless iphawulwe nge-410, 420 kunye ne-440C.
Qaphela, i-duplex (i-austenite ferrite),
④ Intsimbi engatyiwayo, imvula eyenza lukhuni intsimbi engatyiwayo kunye nengxubevange ephezulu enomxholo wentsimbi engaphantsi kwama-50% idla ngokuthatha igama lelungelo elilodwa lomenzi wechiza okanye igama lorhwebo.
① Iisimboli zemichiza yamazwe ngamazwe kunye neempawu zesizwe zisetyenziselwa ukumela ukwakheka kweekhemikhali, kwaye oonobumba besi-Arabhu basetyenziselwa ukumela umxholo wecandelo:
Umzekelo: iChina, iRashiya 12CrNi3A
②Sebenzisa amanani edijithi esisigxina ukumela uchungechunge lwentsimbi okanye amanani; Ngokomzekelo, eUnited States, eJapan, 300 series, 400 series kunye 200 series.
③ Inombolo yothotho yenziwe ngoonobumba besiLatini kunye nomyalelo, obonisa injongo kuphela.
Isicelo, iPinyin yaseTshayina, intsimbi evulekileyo yeziko: P, intsimbi ebilayo: F, intsimbi ebuleweyo: B, iklasi yentsimbi: A, T8: te8
GCr15: Ibhola
◆ intsimbi edibeneyo kunye nentsimbi yasentwasahlobo, efana ne-20CrMnTi 60simn, (umxholo we-C ubonakaliswa kwishumi lamawaka)
◆ insimbi engenasici kunye nensimbi yensimbi yensimbi (umxholo we-C ubonakaliswa ngamawaka), njenge-1 yewaka le-1Cr18Ni9 (okt.
0.1% C), i-stainless C ≤ 0.08%, njenge-0Cr18Ni9, i-ultra-low carbon C ≤ 0.03%, njenge-0cr17ni13mo
Ubunzima ngemitha ye-304L yentsimbi yombhobho = i-diameter yangaphandle - ubukhulu bodonga x ubukhulu bodonga x0.02491
Umxholo we-Element we-304L umbhobho wensimbi engenasici c ≤ 0.03, ni8.00 ~ 12.00, cr18.00 ~ 20.00, Mn <= 2.0, Si <= 1.0, s <= 0.030, P <= 0.035.
I-304L ipayipi yensimbi engenasici i-18cr-8ni-low carbon njenge-Low-C 304 yensimbi, ukuxhathisa kwayo kufana nentsimbi ye-304 ngokubanzi, kodwa ukuxhatshazwa komda we-corrosion boundary yayo kuhle kakhulu emva kwe-welding okanye i-stress relief; Ingakwazi nokugcina ukuxhathisa okulungileyo ngaphandle konyango lobushushu, kwaye ubushushu benkonzo yi-196 ℃ ~ 800 ℃. Isetyenziswe kumashishini angaphandle kumashishini ekhemikhali, amalahle kunye nepetroleum aneemfuno eziphezulu zokumelana nomda wokutya okuziinkozo, iindawo ezinokumelana nokushisa kwezinto zokwakha kunye neengxenye ezinobunzima bonyango lokushisa.
Injongo: ikakhulu isetyenziselwa ubunjineli bamanzi okusela ngokuthe ngqo kunye nolunye uthutho lwamanzi aneemfuno eziphezulu
Iimpawu eziphambili: ubomi benkonzo ende; Isantya esisezantsi sokungaphumeleli kunye nesantya sokuvuza kwamanzi; Ukuhanjiswa komgangatho wamanzi kulungile, kwaye akukho zinto ziyingozi ziya kugalelwa emanzini; Udonga lwangaphakathi lombhobho luhamba kakuhle kwaye lunokumelana nokuhamba kwamanzi aphantsi; Ukusebenza kweendleko eziphezulu, ubomi benkonzo ukuya kwiminyaka eyi-100, akukho kugcinwa kunye neendleko eziphantsi; Inokumelana nokhukuliseko oluphezulu lokuhamba kwamanzi ngaphezu kwe-30m / S; Ukubekwa kombhobho ovezwayo kunye nenkangeleko entle.
Ukusetyenziswa: ishishini lobisi kunye nokutya, ishishini lamachiza, amashishini aneemfuno ezizodwa zangaphakathi zangaphakathi.
Iimpawu zenkqubo: unyango lwangaphakathi lwe-weld bead, unyango lwesisombululo esiluqilima, ukupolisha kwangaphakathi kwe-electrolytic.
Iimpawu zokusebenza: uburhabaxa obungaphakathi beRa bungaphezulu kwe-0.2, intsalela yokuxhoma eludongeni incinci, kulula ukuyicoca, ikhusela ukukhula kwebhaktheriya, i-electrolytic polishing ine-passivation effect, kwaye udonga lwangaphakathi lunomsebenzi wokukhusela olungileyo.
Iindlela zovavanyo: ukuthe tyaba, ukuthambisa okude, ukujika umva, uvavanyo lwe-hydrostatic okanye ukubonwa kwesiphene sangoku, uvavanyo lwepropathi ngoomatshini, uvavanyo loburhabaxa lwangaphakathi.
