FAQ
Q1: Qhov twg yog qhov zoo dua rau txoj kev vuam thiab sib sau?
A: HWM 3030yog ho ntau ductile. Yog tias koj qhov yuav tsum tau muaj kev khoov nyuaj lossis kev sib khi dav dav (xws li cov kab sib txuas), GH3030 yog qhov yooj yim dua los ua haujlwm nrog. GH3044 muaj zog dua tab sis me ntsis rhiab dua thaum tsim khoom.
Q2: Kuv puas tuaj yeem siv GH3030 los hloov GH3044 kom txuag tau nyiaj?
A:Tsuas yog tias koj ua haujlwm kub tsis tshaj 800 degree. Yog tias koj ib puag ncig ncav cuag 900 degree, GH3030 yuav warp thiab poob kev ncaj ncees. Peb pom zoo ibKev xaiv khoomkev sab laj kom tsis txhob "dhau- qhia" lossis "hauv- ua haujlwm."
Q3: Koj puas muab ntawv pov thawj rau aerospace MRO cov haujlwm?
A:Yog lawm. Peb muab tag nrhoMaterial Test Certificate (MTC)per EN 10204 3.1, hla- hais txog qib sib npaug xws li Nimonic 75 lossis XH78T rau GH3030.
Q4: Puas yog GH3044 muaj nyob rau hauv me me diameters li 6 hli?
A:Yog lawm. Peb cov kab ntau lawm npog tag nrho6mm rau 219mmntau yam rau ob qib, txhawb txhua yam los ntawm cov raj ntsuas mus rau cov kav dej hnyav.
