2205 S31803 umbhobho ophindwe kabini ofunyenwe kumashishini apho iikhemikhali zepetroli, ioyile, igesi kunye neekhemikhali.

I-machinability ye-2205 ipayipi yensimbi iphantsi ngenxa yamandla ayo aphezulu. Izantya zokusika ziphantse zibe ngama-20% ngaphantsi kwelo lebanga lama-304.

Umbhobho ophindwe kabini we-2205 awukhuthazwa ukuba usetyenziswe kwiqondo lobushushu elingaphezulu kwe-572¡ãF. Ngenxa yobukho be-chromium ephezulu, i-molybdenum, kunye ne-nitrogen, iityhubhu ezingama-2205 zetsimbi ephindwe kabini zibonisa iipropathi ezikwaziyo ukumelana nomhlwa xa kuthelekiswa nemigangatho yentsimbi engatyiwa ye-austenitic esetyenziswa ngokuqhelekileyo 316 kunye ne-316L kwiindawo ezininzi.

I-A789 UNS S31803 kunye ne-UNS S32205 ngamabakala amabini e-duplex yensimbi engenasici esetyenziswa ngokubanzi kwizicelo ezahlukeneyo zoshishino. Le mibhobho ye-Duplex S31803 engenamthungo iyaziwa ngokumelana nokugqwesa kwayo okugqwesileyo, ukomelela okuphezulu, kunye nokuwelda okulungileyo. I-A789 luphawu olugquma iityhubhu ezingenamthungo nezidityanisiweyo ezenziwe kwi-duplex steel stainless.

Xa kuthelekiswa ne-ferrite, ineplastiki ephezulu kunye nokuqina, akukho brittleness yegumbi, iphucule kakhulu ukuxhathisa kwe-intergranular corrosion kunye nokusebenza kwe-welding, kunye nokugcinwa kwe-475 ¡æ brittleness, high conductivity ye-thermal kunye ne-Superplasticity ye-ferritic stainless steel. Xa kuthelekiswa ne-austenitic steel stainless steel, amandla ayo okuvelisa aphuculwa kakhulu, kwaye ukuchasana kwayo ne-intergranular corrosion, i-corrosion yoxinzelelo, ukukhathala kwe-corrosion kunye ne-abrasion iphuculwe kakhulu.

Ukudibanisa ezininzi iimpawu ezixhamlayo ze-ferritic kunye ne-austenitic steels, i-2205 iyona nto isetyenziswa kakhulu kwi-duplex grade. I-chromium yayo ephezulu kunye ne-molybdenum conutenut inika intsimbi egqwesileyo egqwesileyo ekuxhathiseni ukubola.

I-DIN 933 ngokobuchwephesha isukela kwi-M1. 6 ukuya ku-M52, kanti i-ISO 4017 isuka kwi-M1. 6 ukuya kuM64. Okwesibini, yiloo nto ngokwenene, imigangatho ye-DIN 933 kunye ne-ISO 4017 iyafana ngqo ngaphandle kwe-M10, M12, M14 kunye ne-M22.

Olu nyango lobushushu olwenziwa kwiDuplex 2205 Pipe kufuneka lugcinwe ngokuhambelana nobushushu obuchaziweyo kunye neemeko zokucima.

I-Supler Duplex Steel UNS S32760 stud bolt inamandla esivuno esiphezulu kunye ne-ductility esezantsi kuneentsimbi ze-austenitic ukuze abaqulunqi bombane bafumanise ukuba amandla aphezulu okubumba, ukonyuka kweradiyasi yokugoba, kunye nesibonelelo esongeziweyo se-spring-back ziyimfuneko.

Iibholiti ze-DIN933 ezinemisonto epheleleyo iDuplex Steel S23750-2507 iibholiti zentsimbi ezithambileyo ezithambileyo kunye nabavelisi bamantongomane ngokwesiko.

Izinto eziphathekayo ze-UNS S32760 Stud Bolts zimalunga ne-10% elula xa kuthelekiswa nebakala le-316 yensimbi engenasici. I-Stud Bolt S32760 ibonisa ukusebenza okuphezulu kwimimiselo yokushisa kwe-cryogenic ngokunjalo. Into ethetha ukuba i-ASTM A1082 UNS S32760 ineempawu ezilungileyo ze-ductility zenotshi engaphantsi kwe-zero ukuya kutsho kubushushu obuyi-50¡ãC.

I-alloy 2507 ine-25% yechromium, i-4% ye-molybdenum, kunye ne-7% ye-nickel. Le molybdenum ephezulu, i-chromium kunye ne-nitrogen ibangela ukuxhathisa okugqwesileyo kwi-chloride pitting kunye nokuhlaselwa kwe-crevice corrosion kunye nesakhiwo se-duplex sibonelela nge-2507 ngokuxhathisa okukhethekileyo kwi-chloride yoxinzelelo lwe-corrosion cracking.
