Ibanga likasayizi: ububanzi obungaphandle busuka ku-6 mm ukuya ku-609 mm (NPS 1/4″-24″), ukujiya kodonga 1 mm ukuya ku-40 mm (SCH5S,10S,40S,80S10,20…..160,XXS)
Ubude: 30 amamitha (ubukhulu.)
Inqubo yobuchwepheshe: ukudweba okubandayo noma ukugoqa okubandayo
Isimo sobuso: indawo yokukhetha isixazululo esiqinile; ukupholisha ngomshini; ukukhanya okukhanyayo
Ukwelashwa kokuphela: PE (umlomo oyisicaba), BE (Bevel)
Ukupakisha: isikhwama esilukiweyo esihlanganisiwe / ibhokisi leplywood / ukuthekelisa ibhokisi lamapulangwe
Ukuphawula: Ipayipi lensimbi engagqwali elingajwayelekile lingenziwa ngokwezifiso ngokuya ngezidingo zekhasimende
I-253MA (UNS S30815) iyinsimbi engagqwali ye-austenitic ekwazi ukumelana nokushisa edizayinelwe izinhlelo zokusebenza ezidinga amandla aphezulu okukhasa kanye nokumelana nokugqwala okuhle. Izinga lokushisa layo lokusebenza liyi-850 ~ 1100 °C.
Ukwakheka kwamakhemikhali kwe-253MA kuyalinganisela, okwenza insimbi ibe nokusebenza okuphelele okufanele kakhulu ebangeni lokushisa elingu-850 ° C-1100 ° C, ukumelana ne-oxidation ephakeme kakhulu, izinga lokushisa le-oxidation lifika ku-1150 ° C, kanye nokumelana nokukhuphuka okuphezulu kakhulu. Amandla namandla okuqhekeka okukhasa; ukumelana okuhle kakhulu nokushisa okuphezulu kokugqwala kanye nokumelana nokugqwala kwebhulashi emithonjeni eminingi yamagesi; amandla okukhiqiza okuphezulu namandla okuqina emazingeni okushisa aphezulu; ukuhleleka okuhle nokushisela , kanye nokusebenziseka okwanele.
Ngaphezu kwezakhi ze-alloying i-chromium ne-nickel, insimbi engagqwali engu-253MA iphinde ibe nenani elincane lezinsimbi zomhlaba eziyivelakancane, ngaleyo ndlela ithuthukise kakhulu umthamo wayo wokulwa ne-antioxidant. I-nitrogen yengezwa ukuthuthukisa izakhiwo ze-creep futhi wenze le nsimbi i-austenite ngokuphelele. Nakuba okuqukethwe kwe-chromium ne-nickel kuphansi uma kuqhathaniswa, izinsimbi ezinjalo ezingenasici ezimweni eziningi zinezimo zokushisa ezifanayo njengezinsimbi ze-alloy alloy kanye nama-alloys esisekelo se-nickel.
