5. Cov Lus Nug
Q: Yuav siv tau A105 tau siv rau cov ntawv thov tsawg-?
A: Tsuas yog cia rau-29 degreeCov. Hauv qab no, sivA350 LF2(Muaj ntawv pov thawj rau -46 degree).
Q: Yog astm A105 stainless hlau?
A: Tsis yog, nws yogCov Hlau HlauCov. Rau corrosion kuj, xav txogA182 F304/F316.
Q: Dab tsi yog "n" txhais tau nyob rau hauv A105n?
A: Kev Kho Mob Cua Sov Li Qubrau kev txhim kho cov qauv grain thiab cuam tshuam cov khoom.
Q: Sib npaug rau Aisi 1020?
A: Zoo sib xws, tab sis A105 yogtiv thaiv(tsis dov \/ cam zoo li 1020).
