US 309/309S (UNS S30900/S30908) tšepe

MEFUTA 309                                         ⁠ le le litšepe] litšepe tsa chromium-nickel tse khonang ho mamella kutu le mocheso hammoho le matla a matle sebakeng sa kamore le mocheso o phahameng. Mofuta 309S o tšoana le Mofuta 309 ntle le khabone e tlaase e fokotsang pula ea carbide le ho ntlafatsa ho cheseha.

Alloy 309 le 309S e tsebahala haholo ka tšebeletso ea mocheso o phahameng. Alloy ena e sebetsa hantle ho fihla ho 2000 ° F, haholo-holo haeba khanyetso ea oxidation e hlokahala. 309 le 310 tšepe e sa jeleng paate ke baetsi ba maemo a holimo ba mocheso o phahameng har'a limaraka tse tloaelehileng tse fumanehang setokong sa rona. Tekanyo e phahameng ea nickel le chromium le sebopeho sa lijo-thollo tse mahoashe se fella ka:

• Ntlafatso ea khanyetso ho cyclic oxidation
• Keketseho e hanyetsanang le sulfidation
• Matla a molemo a mocheso o phahameng
• Ntlafatso ea khanyetso ho kutu ea intergranular

309S (UNS S30908) tšepe e sa hloekang ke mofuta o tlase oa khabone ea alloy. E sebelisoa ho etsa hore ho be bonolo ho etsa lintho.

309H (UNS S30909) ke phetoho e phahameng ea k'habone e ntlafalitsoeng bakeng sa khanyetso e matlafalitsoeng ea creep. Hangata boholo ba lijo-thollo le khabone ea poleiti li ka fihlela litlhoko tsa 309S le 309H. Ha mocheso o pakeng tsa 1202 - 1742 ° F (650 - 950 ° C) motsoako o tlas'a pula ea sigma phase. Phekolo ea annealing ea tharollo ka 2012 - 2102 ° F (1100 - 1150 ° C) e tla tsosolosa tekanyo ea boima. Alloy 309 e ka tšeloa habonolo le ho sebetsoa ka mekhoa e tloaelehileng ea ho etsa mabenkele.
