4. 254SMO Inkcazelo:
a. 254SMO yintsimbi ye austenitic stainless. Ngenxa yomgangatho wayo ophezulu we-molybdenum, inokumelana kakhulu ne-corrosion
kunye nomhlwa.
b. Olu hlobo lwensimbi engenasici luphuhliswa ukuze lusetyenziswe kwiindawo ezine-halides ezifana namanzi olwandle. I-254SMO nayo ilungile
ukuxhathisa kwi-corrosion efanayo.
c. Ngokukodwa kwi-asidi equkethe i-halide, intsimbi iphezulu kunentsimbi eqhelekileyo engenasici. Umxholo wayo weC ngu<0.03%, ngoko ubizwa ngokuba
intsimbi esulungekileyo ye-austenitic ecocekileyo (<0.01% ikwabizwa ngokuba yi-super austenitic stainless steel). Super stainless steel luhlobo lwentsimbi ekhethekileyo.
d. Okokuqala, yahlukile kwintsimbi eqhelekileyo engenasici kwimichiza. Kubhekiselele kuhlobo lwentsimbi ephezulu yealloy
iqulethe nickel ephezulu, ikhromium ephezulu kunye ne-molybdenum ephezulu. Eyona idumileyo yi-254SMo equkethe i-6% Mo. Olu hlobo lwentsimbi
inoxhathiso oluhle kakhulu lwendawo ekumhlwa.
e. Inokumelana ne-corrosion ye-pitting elungileyo (PI ≥ 40) kunye noxinzelelo lwe-corrosion ukumelana phantsi kweemeko zamanzi olwandle, i-aeration, i-crevice.
kunye nokukhuhlwa okuphantsi kwesantya.
f. Yimathiriyeli ethatha indawo ye-Ni base alloy kunye ne-titanium alloy. Okwesibini, ngokwemiqathango yokumelana nobushushu obuphezulu okanye ukumelana nokugqwala,
inokumelana neqondo lobushushu eliphezulu kakhulu okanye i-corrosion resistance, engenakubuyiselwa kwi-304 steel stainless. Ukwengeza,
ukusuka kuhlelo lwentsimbi engatyiwa, ubume bemetallographic bentsimbi eyodwa estainless sistable austenitic metallographic structure.
g. Njengoko le ntsimbi ikhethekileyo ingenasici siphezulu, inkqubo yokwenziwa kwayo inzima kakhulu. Ngokuqhelekileyo, abantu banokuthembela kuphela
iinkqubo zesiNtu ukwenza le ntsimbi ikhethekileyo, njengokugalelwa, ukuganga, ukuqengqeleka, njl.
5. Isicelo:
1) Iilwandle: izakhiwo zaselwandle zokusingqongileyo elwandle, ukukhutshwa kwetyuwa emanzini olwandle, i-mariculture, ukutshintshiselana kobushushu bamanzi olwandle, njl.
I-2) Ukukhuselwa kwendalo: isixhobo se-flue gas desulfurization yokuvelisa umbane oshushu, unyango lwamanzi amdaka, njl.
3) Amandla: ukuveliswa kwamandla eathom, ukusetyenziswa ngokupheleleyo kwamalahle, ukuveliswa kwamandla olwandle, njl.
4) Ishishini le-Petrochemical: ukucocwa kweoli, izixhobo zeekhemikhali, njl.
5) Intsimi yokutya: ukwenza ityuwa, ukwenza i-soy sauce, njl.
I-6) Imeko ye-chloride yoxinaniso oluphezulu: imboni yephepha, izixhobo ezahlukeneyo ze-bleaching.
6. Unyango olongezelelweyo:
1) IsiPolish
2) Ukumakisha:
3) Ukupakisha:
7. Ukufakwa Kwesikhongozeli:
