254SMo Material Properties

254SMO yintsimbi ye austenitic stainless.Ngenxa yomgangatho wayo ophezulu we-molybdenum, inokuxhathisa okuphezulu kakhulu kwi-pitting kunye ne-corrosion.Eli bakala lentsimbi engenastainless laphuhliswa laza laphuhliswa ukuze lisetyenziswe kwiindawo ezine-halide ezifana namanzi olwandle.I-254SMO ikwanayo nokumelana kakuhle nokubola okufanayo.Ngokukodwa kwi-halide-containing acids, intsimbi iphezulu kunentsimbi eqhelekileyo engenasici.I-C yayo iqulethe<0.03%, ngoko ibizwa ngokuba yintsimbi ecocekileyo ye-austenitic (<0.01% ikwabizwa ngokuba yi-super austenitic stainless steel).Super stainless steel luhlobo lwentsimbi ekhethekileyo.Okokuqala, yahlukile kwintsimbi eqhelekileyo engenasici kwimichiza.Ibhekisa kwintsimbi yentsimbi engatyiwayo ephezulu ene-nickel ephezulu, i-chromium ephezulu kunye ne-molybdenum ephezulu.Phakathi kwazo, eyona idumileyo yi-254SMo equlethe i-6% ye-Mo. Olu hlobo lwentsimbi lunokumelana nokugqwala okuhle kakhulu kwendawo, kwaye lunokumelana ne-pitting corrosion resistance (PI≥40) kwaye Inokumelana noxinzelelo lwe-corrosion engcono kwaye ithathe indawo ye-Ni- i-alloys esekelwe kunye ne-titanium alloys.Okwesibini, malunga nokumelana nobushushu obuphezulu okanye ukumelana nokugqwala, kunokumelana nobushushu obuphezulu okanye ukuxhathisa ukugqwala, okungenakubuyiselwa kwintsimbi engama-304.Ukongezelela, ukusuka kulwahlulo lwensimbi engenasici, isakhiwo se-metallographic yensimbi ekhethekileyo yensimbi yi-stable austenite metallographic structure.
Ekubeni le ntsimbi ikhethekileyo yentsimbi iyinto ephezulu yealloy, inkqubo yokuvelisa inzima kakhulu.Ngokuqhelekileyo, abantu banokuthembela kuphela kwiinkqubo zemveli zokuvelisa le ntsimbi ekhethekileyo engenasici, njengokufakela, ukubumba, ukuqengqeleka njalo njalo.

254SMo Material Application Areas

1. Ulwandle: izakhiwo zaselwandle kwimekobume yolwandle, ukuchithwa kwamanzi olwandle, ukuveliswa kwamanzi olwandle, ukutshintshisana kobushushu bamanzi olwandle, njl.
2. Intsimi yokukhusela indalo: isixhobo se-flue gas desulfurization yokuvelisa umbane oshushu, ukucocwa kwamanzi amdaka, njl.
3. Indawo yamandla: ukuveliswa kwamandla enyukliya, ukusetyenziswa ngokupheleleyo kwamalahle, ukuveliswa kwamandla kumaza olwandle, njl.njl.
4. Intsimi yePetrochemical: ukucocwa kweoli, izixhobo zeekhemikhali kunye neekhemikhali, njl.
5. Intsimi yokutya: ukwenza ityuwa, ukwenza i-soy sauce, njl.
6. I-high-concentration chloride ion environment: imboni yephepha, izixhobo ezahlukeneyo ze-bleaching
