I-310s insimbi engagqwali i-autenitant arrosion arrosion aronosic arningless allwoy esetshenziswa ezindaweni ezahlukahlukene zokushisa nezindawo zokushisa. Kuyindlela enhle kakhulu yezicelo ezimbonini zama-petrochemical, zamakhemikhali, kanye nokwelapha ukushisa, kanye nezingxenye zomlilo nezinye izinhlelo zokusebenza eziphezulu. Ipuleti lensimbi engama-310s liyifufula eliyisicaba, elincanyana elenziwe kulolu hlelo oluthile.
3.I-253MA (S30815) Iplate yensimbi engenasici
Izici: I-253ma iyinsimbi engamelana nokushisa kwe-auntenitic engavikeleki eyenzelwe izinhlelo zokusebenza ezidinga amandla aphezulu okuqina kanye nokuphikiswa okuhle kokugqwala. Ibanga layo lokushisa elisebenzayo lingu-850-1100 ℃.
I-253MA uhlobo oluthile lwe-alloy yensimbi engenasici eyenzelwe izinhlelo zokushisa okuphezulu. Inikeza ukumelana okuhle kwe-oxidation, i-sulfidation, kanye ne-caribuzization emazingeni okushisa aphakeme. Lokhu kwenza kube lula ukusetshenziswa emikhakhelweni ehlukahlukene, kufaka phakathi lezo ezibandakanya ukushisa nokugqwala, njenge-petrochemical, amandla kagesi, kanye nemikhakha yezimboni zezimboni.Amashidi angama-253A anciphile, izingcezu zezinto eziphansi ezenziwe kuleli alloy. Zisetshenziswa kuzinhlelo zokusebenza ezahlukahlukene lapho inhlanganisela yokumelana nezinga lokushisa okuphezulu nokumelana nokugqwala kubalulekile. Amashidi angasikwa futhi akhiwe abe bobunjwa abahlukahlukene ukuze bahlangabezane nezidingo ezithile zephrojekthi.
Amashidi angama-253A, ukwakheka kwamakhemikhali

I-253ME Plate Corrolion Ukumelana Nendawo Yokusebenzisa Okuyinhloko:
I-OpenCorrosion Ukumelana: I-253MA iqhosha ngokumelana ngo-oxidation axidation, ukumelana nokushisa okushisa kakhulu, namandla obumandla okushisa aphezulu. Iphumelela ikakhulukazi ngaphakathi kobubanzi bokushisa abangama-850 kuya ku-1100 ° C.
Ibanga le-2.Tempeture: Ukusebenza kahle, i-253ma ilungele ukusetshenziswa kububanzi bokushisa abangama-850 kuya ku-1100 ° C. Emazingeni okushisa aphakathi kuka-600 no-850 ° C, kwenzeka izinguquko ezihlelekile, okuholele ekunciphiseni ubumbano oluncishisiwe ekushiseni kwegumbi.
Amandla we-3.MeChanical: Le alloy idlula ama-steres ajwayelekile angenasici, njengama-304 nama-340, ngokuya ngamandla esikhashana esisheshayo emazingeni okushisa ahlukahlukene angaphezu kwama-20%.
Ukwakheka kwe-4.creamical: I-253MA ifaka ukwakheka kwamakhemikhali okulinganiselayo okunikeza ukusebenza okuhlukile ebangeni lokushisa lama-850-1100 ° C. Kukhonjiswa ukumelana kakhulu oxidation, ukumelana namazinga okushisa aze afike ku-1150 ° C. Inikeza nokumelana nokuqina okuphezulu namandla okuqhekeka.
Ukumelana kwe-5.corrosion: Ngaphezu kwamakhono ayo okushisa aphezulu, ama-253MA abonisa ukumelana okuhle kakhulu ekugqwaneni okushisa okuphezulu kanye nokugqwayiza izimo ezindaweni eziningi ezisezingeni eliphakeme.
6.Strength: Amandla aphezulu okuvutha kanye namandla ashubile emazingeni okushisa aphakeme.
I-7.formability kanye nokushaywa kwe-welduality: 253mA yaziwa ngokwenza kwayo okuhle, i-welchimability, kanye nemishini.
