904L Material Properties
Nekuti iyo kabhoni ye904L yakadzikira kwazvo (0.020% yakanyanya), hapazove nekunaya kwecarbide kana iri nyaya yekupisa kwekupisa uye welding.Izvi zvinobvisa njodzi ye intergranular corrosion inowanzoitika mushure mekupisa kurapwa uye welding.Nekuda kweiyo yakakwira chromium-nickel-molybdenum zvirimo uye kuwedzerwa kwemhangura, 904L inogona kupfuudzwa kunyangwe mukuderedza nharaunda senge sulfuric uye formic acids.Iyo yakakwira nickel yemukati zvakare inokonzeresa yakaderera corrosion mwero mumamiriro anoshanda.Mune yakachena sulfuric acid muhuwandu hwehuwandu hwe0 ~ 98%, tembiricha yekushandisa ye904L inogona kunge yakakwira se40 degrees Celsius.Mune yakachena phosphoric acid muhuwandu hwehuwandu hwe0 ~ 85%, kupikisa kwayo kwekuora kwakanaka kwazvo.Muindasitiri phosphoric asidhi inogadzirwa nekunyorova maitiro, tsvina ine simba rakasimba pakuramba kwecorrosion.Pane ese akasiyana siyana phosphoric acids, 904L inonyanya kuomarara kupfuura yakajairwa simbi isina tsvina.Mune yakasimba oxidizing nitric acid, 904L ine yakaderera corrosion resistance pane yakanyanya alloyed simbi mamakisi asina molybdenum.Mu hydrochloric acid, kushandiswa kwe 904L kunogumira kune yakaderera mazinga e1-2%.mune iyi 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 mune chloride mhinduro zvakare yakanaka kwazvo.Iyo yakakwira nickel ye904L inoderedza mwero wekuora mumakomba nemakomba.Ordinary austenitic stainless steels inogona kukonzeresa kuonda munzvimbo ine chloride-rich patembiricha inopfuura 60 ° C, uye kurudziro iyi inogona kuderedzwa nekuwedzera nickel yemukati yesimbi isina tsvina.Nekuda kweiyo yakakwira nickel yemukati, 904L inoshingirira zvakanyanya kushushikana nekupwanya kwecorrosion mumigadziriso yechloride, yakadzika hydroxide mhinduro uye hydrogen sulfide yakapfuma nharaunda.
904L Material Application Nzvimbo
1.Petroleum, petrochemical midziyo, yakadai semagetsi mune petrochemical equipment, nezvimwewo.
2.Kuchengetedza uye midziyo yekutakura ye sulfuric acid, yakadai semagetsi ekupisa, nezvimwewo.
3. Iyo flue gasi desulfurization mudziyo mumagetsi emagetsi inonyanya kushandiswa mu: shongwe yemuviri weiyo absorption tower, flue, shutter, mukati memukati, iyo spray system, nezvimwe.
4.Scrubbers uye mafeni mu organic acid treatment systems.
5.Seawater treatment michina, mvura yegungwa inopisa kupisa, mapepa emabhizimisi emidziyo, sulfuric acid, nitric acid midziyo, kugadzirwa kweasidhi, indasitiri yemishonga nemimwe michina yemakemikari, midziyo yekumanikidza, midziyo yezvokudya.
6. Pharmaceutical plants: centrifuges, reactors, nezvimwewo.
7.Chikafu chekudyara: soy sauce zvirongo, kubika waini, zvirongo zvemunyu, midziyo uye zvipfeko.
8.904L ndiyo inoenderana simbi giredhi kune yakasimba corrosive medium ye dilute sulfuric acid.
