| Uphawu: | Inamandla aphezulu e-thermal (δb≥440MPa) kunye nokumelana ne-oxidation kwiqondo lokushisa eliphezulu, kwaye inokumelana okuthile ne-hydrogen corrosion. I-coefficient yokwandiswa kwe-thermal incinci, i-conductivity ye-thermal iphezulu, inkqubo yokusebenza kakuhle, iqondo lokushisa li-450-620 degrees Celsius, ukuthambekela kokuqina kwentsimbi kucacile, kwaye i-weldability impofu. Isetyenziswa kakhulu ekwenzeni ii-injini zomphunga kunye neebhoyila, kwaye isetyenziswa kakhulu kwiityhubhu zokutshintsha ubushushu kunye nobushushu obuphezulu kunye neenqanawa zoxinzelelo oluphezulu. | Inokumelana ne-oxidation elungileyo malunga ne-650 degrees celsius, amandla alungileyo e-thermal angaphantsi kwama-600, ukufunxwa kakuhle komothuko kunye ne-thermal conductivity, kwaye isetyenziswa kakhulu kwiiinjini zomphunga. Nangona kunjalo, olu hlobo lwentsimbi lunotyekelo olukhulu lokuqina kwaye lunokusebenza kakubi kwe-welding. Ineempawu ezilungileyo zobushushu obuphezulu obuphezulu, uzinzo lwe-microstructure, ukumelana nokubola, kunye nokuqina okulungileyo. Isetyenziswa kakhulu kwi-petrochemical, ukuguqulwa kwamalahle, amandla enyukliya, ibhloko ye-injini ye-injini yomphunga, ibhoyila yamandla e-thermal kunye nezinye iimeko zokusebenza ezirhabaxa, imekobume yeendaba ezonakalisayo. | ||
| Isicelo: | I-petroleum, i-petrochemical, iibhoyila ezinoxinzelelo oluphezulu, kunye neminye imibhobho yenjongo eyodwa engenamthungo ibandakanya imibhobho yebhoyila engenamthungo, imibhobho yentsimbi engenamthungo yokwakheka komhlaba, kunye nemibhobho yepetroleum engenamthungo. Imibhobho kunye ne-forgings ingasetyenziselwa kwiinqanawa zoxinzelelo. imibhobho yomphunga kunye neentloko ezinobushushu bodonga ≤510 ℃; Umbhobho wokufudumeza umphezulu kunye nobushushu bodonga ≤540 ℃. | Ubushushu obuphezulu be-sulfure umhlwa, ubushushu obuphezulu be-hydrogen kunye ne-hydrogen sulfide corrosion, i-organic acid corrosion. Reheater ityhubhu ngodonga ubushushu 630 ℃ -650 ℃. Imibhobho kunye ne-forgings ingasetyenziselwa kwiinqanawa zoxinzelelo. Ubushushu obuphezulu be-sulfure umhlwa, ubushushu obuphezulu be-hydrogen kunye ne-hydrogen sulfide corrosion, i-organic acid corrosion. I-Reheater ityhubhu enodonga lobushushu lwe-630 ℃ -650 ℃. | ||
