Haynes 188 Alloy Qws piav qhia
Haynes 188 alloy yog cobalt-nickel-chromium-tungsten alloy uas ua ke zoo heev kub lub zog nrog zoo heev tiv thaiv oxidizing ib puag ncig mus txog 2000℉ (1095 degree) rau ntev raug thiab zoo heev tiv thaiv sulfate deposit kub corrosion. Nws yog yooj yim fabricated thiab tsim los ntawm cov txheej txheem pa, thiab tau siv rau cam khwb cia tivthaiv. Lwm cov yam ntxwv ntxim nyiam suav nrog kev ua haujlwm zoo heev rau cov ntsev chloride ntsev, thiab ua haujlwm zoo rau gaseous sulfidation.
Haynes 188 alloy yog cov khoom siv sib zog ua kom muaj zog uas sib xyaw ua ke zoo heev kub lub zog. Nws yog qhov tshwj xeeb tshaj yog siv rau kev siv mus sij hawm ntev ntawm qhov kub ntawm 1200℉ (650 degree) lossis ntau dua. Nws muaj zog dua li nickel-base solid-solution ntxiv dag zog rau cov alloys, thiab muaj zog dua li cov nickel-chromium yooj yim los yog hlau-nickel-chromium alloys thaum tshav kub kub-resistant alloys.
Qib siab chromium ua ke nrog me me ntxiv ntawm lanthanum ua rau muaj kev mob siab heev thiab tiv thaiv. Cov hlau tseem muaj qhov zoo sulfidation tsis kam thiab zoo heev metallurgical stability raws li pom los ntawm nws cov ductility zoo tom qab ntev raug rau qhov kub siab. Zoo fabricability thiab weldability ua ke los ua cov alloy pab tau nyob rau hauv cov roj turbine daim ntaub ntawv xws li combustors, nplaim tuav, liners thiab hloov ducts.
