| Hunhu: | Iyo ine yakakwirira yekupisa simba (δb≥440MPa) uye oxidation kuramba pakupisa kwepamusoro, uye ine kumwe kupikisa kune hydrogen corrosion. The coefficient of thermal kuwedzera idiki, thermal conductivity yakakwira, process performance yakanaka, tembiricha iri 450-620 madhigirii Celsius, kuomarara kwesimbi kuri pachena, uye weldability yakashata. Inoshandiswa zvakanyanya mukugadzira turbines uye boilers, uye inonyanya kushandiswa mukupisa exchanger machubhu uye yakakwirira-tembiricha uye yakanyanya-kudzvanywa midziyo. | Iyo ine yakanaka oxidation kuramba yakatenderedza 650 madhigirii celsius, yakanaka yekupisa simba iri pasi pe600, yakanaka kunyura uye yekupisa conductivity, uye inoshandiswa zvakanyanya mumaturbines ehutsi. Zvisinei, rudzi urwu rwesimbi rune tsika yakakura yekuomesa uye ine urombo husina kunaka. Iine yakanaka yepamusoro tembiricha michina zvimiro, microstructure kugadzikana, corrosion resistance, uye kuoma kwakanaka. Inoshandiswa zvakanyanya mu petrochemical, marasha shanduko, simba renyukireya, steam turbine block, thermal power boiler uye mamwe mamiriro ekushanda akaomarara, corrosive media environment. | ||
| Application: | Petroleum, petrochemical, high-pressure boilers, uye mamwe-akakosha-chinangwa mapaipi asina musono anosanganisira boiler isina musono pombi, geological seamless simbi pombi, uye petroleum isina musono pombi. Mapombi uye forgings anogona kushandiswa mumanikidziro midziyo. Mapombi emvura uye misoro ine tembiricha yemadziro ≤510 ℃; Kupisa pamusoro pechubhu nemadziro tembiricha ≤540 ℃. | High tembiricha sarufa ngura, tembiricha yehydrogen uye hydrogen sulfide corrosion, organic acid corrosion. Reheater chubhu ine madziro tembiricha ye630 ℃ -650 ℃. Mapombi uye forgings anogona kushandiswa mumanikidziro midziyo. High tembiricha sarufa ngura, tembiricha yehydrogen uye hydrogen sulfide corrosion, organic acid corrosion. Reheater chubhu ine madziro tembiricha ye630 ℃ -650 ℃. | ||
