I-310S insimbi engenasici yintsimbi enganyangekiyo ye-austenitic enganyangekiyo esetyenziswa kwiindawo ezahlukeneyo zobushushu obuphezulu kunye neendawo ezidlayo. Lolona khetho lubalaseleyo kwizicelo kwimizi-mveliso yepetrochemical, imichiza, kunye nobushushu, kunye namacandelo eziko kunye nezinye izicelo ezinobushushu obuphezulu. I-310S ipleyiti yensimbi engenasici licwecwe elisicaba, elibhityileyo elenziwe ngalo mxube uthile.

3.I-253MA (S30815) ipleyiti yensimbi engenasici

Iimpawu: I-253MA yintsimbi enganyangekiyo ye-Austenitic enganyangekiyo eyenzelwe usetyenziso olufuna amandla aphezulu okurhubuluza kunye nokumelana nokugqwesa okuhle. Umgangatho wobushushu osebenzayo yi-850-1100 ℃.

I-253MA luhlobo oluthile lwe-alloy yensimbi engenasici eyenzelwe izicelo eziphezulu zokushisa. Inika ukuchasana okugqwesileyo kwi-oxidation, i-sulfidation, kunye ne-carburization kumaqondo obushushu aphezulu. Oku kuyenza ilungele ukusetyenziswa kumashishini ahlukeneyo, kuquka lawo abandakanya ubushushu kunye nokudleka, njengepetrochemical, ukuveliswa kwamandla, kunye namacandelo eziko lemizi-mveliso.Amaphepha e-253MA ngamaqhekeza amancinci, asicaba enziwe ngale ngxubevange. Zisetyenziswa kwizicelo ezahlukeneyo apho udibaniso lokumelana nobushushu obuphezulu kunye nokumelana ne-corrosion kubalulekile. Amaphepha anokusikwa aze abunjwe abe ziimilo ezahlukeneyo ukuhlangabezana neemfuno ezithile zeprojekthi.

253MA Amaphepha, iiPlates Ukubunjwa kwemichiza

Iipropati ze-253MA Plate Mechanical

I-253MA yokuxhathisa i-Plate Corrosion kunye nendawo yokusetyenziswa ephambili:

I-1.I-Corrosion Resistance: I-253MA iqhayisa ukuxhathisa okugqwesileyo kwe-oxidation, ukumelana nobushushu obuphezulu be-corrosion, kunye namandla amangalisayo obushushu obuphezulu. Isebenza ngokukodwa phakathi kobushushu obuphakathi kwama-850 ukuya kwi-1100°C.

I-2.Uluhlu lweTemperature: Ukusebenza kakuhle, i-253MA ifaneleka ngokufanelekileyo ukusetyenziswa ngaphakathi kwendawo yokushisa ye-850 ukuya kwi-1100 ° C. Kwiqondo lokushisa phakathi kwe-600 kunye ne-850 ° C, utshintsho lwesakhiwo lwenzeka, olukhokelela ekunciphiseni ukuqina kwempembelelo kwiqondo lokushisa.

3.Amandla omatshini: Le alloy idlula iintsimbi eziqhelekileyo ezingenasici, ezifana ne-304 kunye ne-310S, malunga namandla e-tensile yexesha elifutshane kumaqondo okushisa ahlukeneyo ngaphezu kwe-20%.

I-4.Ukwakheka kweeKhemikhali: I-253MA ibonakalisa ukubunjwa kweekhemikhali ezilungeleleneyo ezinikezela ukusebenza okukhethekileyo kwiqondo lokushisa kwe-850-1100 ° C. Ibonisa ukuxhathisa okuphezulu kakhulu kwe-oxidation, ukumelana namaqondo obushushu ukuya kwi-1150 °C. Ikwabonelela ngamandla okumelana ne-creep kunye namandla e-creep fracture.

I-5.I-Corrosion Resistance: Ukongeza kumandla ayo aphezulu obushushu, i-253MA ibonisa ukuxhathisa okugqwesileyo kwi-corrosion ephezulu yobushushu kunye ne-brush corrosion kwiindawo ezininzi zegesi.

6.Amandla: Inamandla esivuno esiphezulu kunye namandla okuqina kumaqondo obushushu aphezulu.

I-7.I-Formability kunye ne-Weldability: I-253MA iyaziwa ngokubunjwa kwayo kakuhle, i-weldability, kunye ne-machinability.
