4. 254SMO Incazelo:

a. I-254SMO iyinsimbi engagqwali ye-austenitic. Ngenxa yokuqukethwe kwayo okuphezulu kwe-molybdenum, inokumelana okuphezulu kakhulu nokugqwala

nokugqwala kwemifantu.

b. Lolu hlobo lwensimbi engagqwali luthuthukiswa ukuze lusetshenziswe ezindaweni eziqukethe ama-halides njengamanzi olwandle. I-254SMO nayo inokuhle

ukumelana nokugqwala okufanayo.

c. Ikakhulukazi ku-asidi equkethe i-halide, insimbi iphakeme kunensimbi engagqwali evamile. Okuqukethwe kwayo kwe-C kungu-<0.03%, ngakho kubizwa

i-pure austenitic stainless steel (<0.01% ibizwa nangokuthi i-super austenitic stainless steel). Insimbi engagqwali iwuhlobo lwensimbi ekhethekile engagqwali.

d. Okokuqala, ihlukile kunensimbi engagqwali evamile ekwakhiweni kwamakhemikhali. Kubhekiselwa ohlotsheni lwensimbi engagqwali ephezulu

equkethe i-nickel ephezulu, i-chromium ephezulu ne-molybdenum ephezulu. Edume kakhulu i-254SMo equkethe u-6% Mo. Lolu hlobo lwensimbi

inokumelana nokugqwala okuhle kwendawo.

e. Inokumelana nokugqwala okuhle kwe-pitting (PI ≥ 40) kanye nokumelana nokugqwala kwengcindezi ngaphansi kwezimo zamanzi olwandle, i-aeration, i-crevice.

nokuhlikihla ngesivinini esiphansi.

f. Iyingxenye ye-Ni base alloy ne-titanium alloy. Okwesibili, mayelana nokumelana nokushisa okuphezulu noma ukumelana nokugqwala,

inokumelana nezinga lokushisa eliphezulu okuhle kakhulu noma ukumelana nokugqwala, okungenakuthathelwa indawo ngensimbi engagqwali engu-304. Ngaphezu kwalokho,

kusukela ekuhlukaniseni insimbi engagqwali, isakhiwo se-metallographic sensimbi engagqwali ekhethekile iyisakhiwo esiqinile se-austenitic metallographic.

g. Njengoba le nsimbi ekhethekile engagqwali iyi-alloy material ephezulu, inqubo yayo yokukhiqiza iyinkimbinkimbi impela. Ngokuvamile, abantu bangathembela kuphela

izinqubo zendabuko zokukhiqiza le nsimbi ekhethekile engagqwali, njengokuthela, ukufoja, ukugingqa, njll.

5. Isicelo:

I-1) Izilwandle: izakhiwo zasolwandle zemvelo yasolwandle, ukuchithwa kwamanzi olwandle usawoti, i-mariculture, ukushintshaniswa kokushisa kwamanzi olwandle, njll.

I-2) Ukuvikelwa kwemvelo: idivayisi ye-flue gas desulfurization yokukhiqiza amandla ashisayo, ukwelashwa kwamanzi angcolile, njll.

3) Amandla: ukukhiqizwa kwamandla e-athomu, ukusetshenziswa okuphelele kwamalahle, ukukhiqizwa kwamandla olwandle, njll.

4) Imboni ye-petrochemical: ukucwenga uwoyela, imishini yamakhemikhali, njll.

5) Inkambu yokudla: ukwenza usawoti, ukuphisa isoso sososi, njll.

I-6) Imvelo ye-chloride yokuhlushwa ephezulu: imboni yephepha, amadivaysi ahlukahlukene wokuxubha.

6. Ukwelashwa okwengeziwe:

1) IsiPolish
