S32750 Steel Engenamthungo Tubing

Inkcazelo emfutshane:

I-alloy 2507, kunye nenombolo ye-UNS i-S32750, i-alloy yesigaba sesibini esekelwe kwi-iron-chromium-nickel system kunye nesakhiwo esixutywe malunga nemilinganiselo elinganayo ye-austenite kunye ne-ferrite. Ngenxa yolungelelwaniso lwesigaba se-duplex, i-alloy 2507 ibonisa ukuxhathisa okugqwesileyo kwi-corrosion jikelele efana ne-austenitic stainless steels kunye nezinto ezifanayo zokudibanisa. Ngaphandle koko, inokuqina okuphezulu kunye namandla emveliso kunye nokuchasana kwe-Chloride ye-SCC engcono kakhulu kune-austenitic esebenza nayo ngelixa igcina ukuqina kwempembelelo engcono kune-ferritic efanayo.

Intshayelelo yeMveliso

I-Super Duplex engenastainless njenge-S32750, i-microstructure edibeneyo ye-austenite kunye ne-ferrite (50/50) eye yaphucula amandla ngaphezu kwe-ferritic kunye ne-austenitic steel grade. Umahluko ophambili kukuba i-Super Duplex inomthamo ophezulu we-molybdenum kunye ne-chromium enika imathiriyeli enkulu I-chromium ephezulu iphinda ikhuthaze ukwakheka kwezigaba ezinobungozi ze-intermetallic, ezibuthathaka kwi-475 ° C ebrittlement ngenxa yokuwa kwesigaba se-α' esine-chromium, kunye ne-embrittlement nge-sigma, chi kunye nezinye izigaba kumaqondo aphezulu.

I-alloy 2507 (S32750) nayo inomxholo ophezulu we-nitrogen, ongakhuthazi nje ukubunjwa kwe-austenite kunye nokwandisa amandla, kodwa ukulibazisa ukubunjwa kwezigaba ze-intermetallic ngokwaneleyo ukuvumela ukucutshungulwa kunye nokuveliswa kwebakala le-duplex.

Ibakala libonakaliswe ngokumelana nokugqwesa kwekloride entle kakhulu, kudityaniswe namandla omatshini aphezulu kakhulu. Ilungele ukusetyenziswa kwiindawo ezinobundlobongela njengamanzi olwandle afudumeleyo akloriniweyo kunye nemithombo yeendaba enekloridi eneasidi.

I-alloy 2507 (S32750) iimpawu zezi zilandelayo:

● Ukumelana okugqwesileyo kuxinzelelo lwe-corrosion cracking (SCC) kwiindawo ezithwele i-chloride
● Ukumelana okugqwesileyo kwimingxuma kunye nokuhlwa kwemingxuma
● Ukuxhathisa okuphezulu kwi-corrosion jikelele
● Amandla omatshini aphezulu kakhulu
● Iimpawu ezibonakalayo ezibonelela ngeenzuzo zoyilo
● Ukuxhathisa okuphezulu kukhukuliseko kunye nokudinwa kwe-corrosion
● Ukuwelda kakuhle

I-S32750 yenzelwe izicelo ezifuna amandla akhethekileyo kunye nokumelana nomhlwa, ezifumanekainkqubo yemichiza, izixhobo zepetrochemical, kunye namanzi olwandle. Isetyenziswa ngokubanzi kwi-oyile ye-offshore kunye negesi yokuhlola / imveliso kunye nokutshintshana kobushushu kwi-petrochemical / processing processing. Eli bakala likwafanelekile kwi-hydraulic kunye nezixhobo zezixhobo kwiindawo zaselwandle ezishushu.
