904L|N08904 Alloy Steel Plate
Tsanangudzo Pfupi
904L austenitic Stainless simbi ndeyepasi-kabhoni, yakakwira nickel, molybdenum austenitic simbi isina simbi ine acid resistance.904L austenitic Stainless simbi ine yakanakisa activation passivation shanduko kugona, yakanakisa kusaora ngura, yakanaka corrosion resistance mune asiri oxidizing acids akadai se sulfuric acid, acetic acid, formic acid, uye phosphoric acid, kuramba kwakanaka kugomba corrosion mune neutral chloride ion media, uye yakanaka. kupikisa kukoromoka kwemukororo uye kushushikana kwekuora mwoyo.Inokodzera kwakasiyana siyana ye sulfuric acid iri pasi pe70 ℃, ine yakanaka corrosion resistance kune chero kusungwa uye tembiricha yeacetic acid uye musanganiswa wefomic acid uye acetic acid pasi pekumanikidzwa kwakajairwa.
904L ndeye yakaderera kabhoni yemukati, yakakwira alloying austenitic Stainless simbi yakagadzirirwa kuomarara nharaunda.Iyo ine nani corrosion resistance pane 316L uye 317L, uku ichienzanisa mutengo nekuita, uye ine yakakwirira mutengo-inoshanda.Nekuda kwekuwedzera kwe1.5% mhangura, ine yakanakisa corrosion resistance yekudzikisa maasidhi akaita sesulfuric acid uye phosphoric acid.Iyo zvakare ine yakanakisa corrosion kuramba kushushikana corrosion, pitting corrosion, uye crevice corrosion inokonzerwa ne chloride ion, uye ine kuramba kwakanaka kune intergranular corrosion.Mu pure sulfuric acid ine concentration range ye 0-98%, tembiricha yekushandisa ye904L inogona kusvika kusvika 40 degrees Celsius.Mune yakachena phosphoric acid ine huwandu hwehuwandu hwe 0-85%, kushora kwayo kwekudzivirira kwakanaka kwazvo.Kusachena kune simba rakasimba pakuramba kwecorrosion yeindasitiri phosphoric acid inogadzirwa nehunyoro process tekinoroji.Pakati pemhando dzese dzephosphoric acid, 904L ine corrosion irinani kuramba pane yakajairwa simbi isina tsvina.Mune yakanyanya oxidizing nitric acid, 904L ine yakaderera corrosion resistance kana ichienzaniswa nepamusoro alloyed simbi mamakisi asina molybdenum.Mu hydrochloric acid, kushandiswa kwe 904L kunogumira kune yakaderera mazinga e1-2%.Mukati meiyo concentration range.Iyo corrosion resistance ye904L iri nani pane yeyakajairika simbi isina tsvina.904L simbi ine yakakwirira kuramba kugomba ngura.Kupokana kwayo kune crevice corrosion mu chloride solution.Simba racho rakanaka zvakare.Iyo yakakwira nickel ye904L inoderedza kukora mumakomba nemakomba.Ordinary austenitic Stainless simbi inogona kunzwira kushushikana kwecorrosion munzvimbo ine chloride yakawanda patembiricha iri pamusoro pe60 degrees Celsius.Nekuwedzera nickel yemukati yesimbi isina tsvina, iyi sensitization inogona kuderedzwa.Nekuda kweiyo yakakwira nickel yemukati, 904L inoratidza kupikisa kwakanyanya kushushikana nekupwanya mukupwanya mune chloride mhinduro, concentrated hydroxide solution, uye nharaunda dzakapfuma muhydrogen sulfide.
Petroleum uye petrochemical midziyo, senge mareactor mu petrochemical midziyo, chengetedzo uye midziyo yekufambisa ye sulfuric acid, senge zvinopisa kupisa, magetsi plant flue gasi desulfurization zvishandiso, zvinonyanya kushandiswa mumuviri weshongwe, flue, mapaneru emagonhi, zvemukati zvemukati, masisitimu ekupfapfaidza, nezvimwe zvekunyura shongwe, zvinogezesa uye mafeni mune organic acid kurapwa masisitimu, midziyo yekuchenesa mvura yegungwa, kupisa kwemvura yegungwa, kugadzira mapepa eindasitiri midziyo, sulfuric acid uye nitric acid midziyo, kugadzirwa kweasidhi, etc Indasitiri yemishonga nemimwe michina yemakemikari, midziyo yekumanikidza, midziyo yechikafu. , mafekitari emishonga: macentrifuges, reactors, etc., chikafu chekudyara: soy sauce matangi, waini yekubikisa, matangi emunyu, midziyo uye mapfekero, 904L igiredhi resimbi rinoenderana redhilute sulfuric acid yakasimba corrosive medium.
Plate, strip, bar, waya, forging, tsvimbo yakatsetseka, welding material, flange, etc., inogona kugadziriswa zvinoenderana nedhirowa.
