Alloy e phahameng ea mocheso
◆GH2132 (incoloyA-286 / S66286) e na le ts'ebetso e ntle ka kakaretso le moeli oa lihlahisoa tse phahameng. E sebelisetsoa li-discs tsa turbine, 'mele oa selikalikoe, li-welds tsa bracket le lisebelisoa tsa likarolo tsa matšeliso tse ka tlase ho 700 °C.
◆GH3030 alloy e na le sebopeho se tsitsitseng, botsofali bo fokolang, le khanyetso e ntle ea oxidation. E loketse likamore tse tukang le li-afterburners ka tlase ho 800 ° C.
◆GH3128 e na le ts'ebetso e ntle e felletseng, e tšoarella haholo, e hanyetsa oxidation e ntle, botsitso bo botle ba sebopeho le ts'ebetso e ntle ea welding, 'me e sebelisoa haholo-holo bakeng sa kamore ea mollo le likarolo tsa morao-rao tsa enjene ea turbine e nang le mocheso o sebetsang oa 950 ° C.
◆GH4145 (inconelx-750 / N07750) e na le matla a lekaneng, ho hanyetsa kutu le khanyetso ea oxidation ka tlase ho 980 ° C. Ke thepa e ratoang bakeng sa liliba tse matla haholo 'me e loketse ho etsa li-diaphragm tse elastic le lipampitšana tsa ho tiisa.
◆GH4169 (N07718/inconel718) e na le sebopeho sa austenite, 'me karolo ea "Y" e entsoeng ka mor'a ho thatafala ha pula e etsa hore e be le thepa e babatsehang ea mochine. E sebelisoa haholo libakeng tse fapaneng tse nang le litlhoko tse phahameng tsa ho hanyetsa mocheso.
◆GH4080A (N07080 / Nimonic80A) Z e na le mocheso o phahameng o lekaneng ho 700-750 ° C le khanyetso e ntle ea oksijene ka tlase ho 900 ° C. Alloy ena e khethehileng e loketse masimo a hlokang matla a phahameng le ho hanyetsa kutu.
◆GH3044 Kamore e ka sehloohong ea mollo le likarolo tsa afterburner, lithebe tsa mocheso, li-vanes tsa tataiso, joalo-joalo.
◆GH4080A e na le khanyetso e ntle ea creep le khanyetso ea oxidation sebakeng sa 650-850 ° C.
◆GH2136 e na le ts'ebetso e ntle ka kakaretso, sebopeho se tsitsitseng ka mor'a tšebeliso ea nako e telele, khanyetso e ntle ea oxidation, coefficient e nyenyane ea ho atolosa linear, le welding e bonolo le ho theha.
◆ GH2036 Turbine discs, lithebe tsa mocheso, mehele ea ho boloka, mehele ea ho jara, li-fasteners, joalo-joalo tse sebetsang ka tlase ho 650 °C.
◆GH4738 e loketse ho etsa li-turbine discs, li-blades tse sebetsang, li-fasteners tse phahameng tsa mocheso, li-tubes tsa mollo, li-shafts le li-turbine, joalo-joalo.
