FAQ
Q1: Yuav ua li cas koj lav lub neej qaug zog ntawm koj GH4169 rods?
A: Lub neej qaug zog yog khi rau purity thiab grain loj. Los ntawm kev sivVIM+VARmuab ob npaug rau melting thiab cov txheej txheem forging / kev daws teeb meem, peb tuav ib qho ultra-cov qauv lis piam (Qib 8 los yog finer), uas tiv thaiv cov kev ntxhov siab hauv zos uas ua rau qaug zog tawg.
Q2: Cov rods puas yuav dhau Class A Ultrasonic Testing (UT)?
A: Yog lawm.Tag nrho peb cov qib Aviation rods yog 100% UT kuaj. Cov txheej txheem VIM + VAR tshem tawm cov "dawb pob" thiab macro- kev cais tawm uas feem ntau ua rau UT tsis lees paub hauv qis dua - cov ntaub ntawv zoo.
