ASTM 304 vs SUS304: Qhov tseem ceeb sib txawv ntawm cov qauv

Qhov tseem ceeb sib txawv (Chemical Composition)

Keeb kwm Standard: ASTM (SS304) vs JIS (SUS304).

Chromium (Cr): SUS304 (18-20%) vs. SS304 (17.5-19.5%) – SUS304 muaj qhov dav me ntsis, muaj peev xwm ntau dua.

Silicon (Si): SUS304 ( Tsawg dua lossis sib npaug li 1.00%) vs. SS304 ( Tsawg dua lossis sib npaug li 0.75%) - SUS304 tso cai rau Silicon ntau dua.

Cov pa roj carbon (C): Ob leeg yog tsawg (tsawg dua los yog sib npaug rau 0.08%), tseem ceeb heev rau weldability, tab sis ASTM 304 tej zaum yuav muaj ib tug nruj max (0.07%).

Nickel (Ni): Ob leeg zoo ib yam (8-10.5%).

Cov yam ntxwv tseem ceeb (Properties & Use)

Qib: Ob leeg yog Hom 304 stainless hlau, feem ntau hom.

Corrosion Resistance: Zoo heev vim muaj cov ntsiab lus Chromium thiab Nickel siab (18/8).

Weldability: Ob leeg muab kev sib txuas zoo.

Daim ntawv thov: Lub hom phiaj dav dav, kev ua zaub mov, chav ua noj, architectural.

Hauv cov ntsiab lus yooj yim:
Xav txog lawv li menyuam ntxaib los ntawm ntau lub tebchaws; lawv saib thiab ua yuav luag zoo ib yam, tab sis lawv daim ntawv pov thawj hnub yug (cov qauv) teev cov kev sib txawv me ntsis rau cov me "cov yam ntxwv" (cov ntsiab lus). Rau feem ntau cov haujlwm, koj tuaj yeem siv lawv sib hloov, tab sis rau qhov tshwj xeeb engineering, xyuas cov khoom siv tshwj xeeb.
