ASTM 304 vs SUS304: Qhov txawv yog dab tsi?

Qhov tseem ceeb sib txawv & Zoo sib xws

Qauv:SUS304 yog nyob rau hauv Japanese JIS cov qauv (JIS G 4304/4305), thaum SS304/304 nyob rau hauv American ASTM qauv (ASTM A240).

Kev sib xyaw:Ze li ntawm 18% Chromium (Cr) thiab 8% Nickel (Ni) cov ntsiab lus, ua rau lawv "18/8" hlau.

Qhov txawv me ntsis:SUS304 tej zaum yuav muaj ib tug me ntsis siab dua Chromium ntau (18-20%) tshaj ASTM 304 (17.5-19.5%), muab ruaj khov heev corrosion kuj.

Khoom:Ob leeg muaj kev tiv thaiv corrosion zoo heev, weldability, formability, thiab txhua yam muaj zog, nrog rau cov kev hloov pauv tsawg thiab nyob ntawm kev tsim khoom tshwj xeeb.

Daim ntawv thov:SUS304 yog ib txwm muaj nyob rau hauv Asian lag luam (Nyiv), thaum SS304 muaj nyob rau hauv North America thiab Europe, ua rau lub regional nrhiav qhov tseem ceeb txiav txim.

Thaum twg xaiv qhov twg

Rau Asian/Japanese Projects:XaivSUS 304kom ua raws li cov qauv hauv zos thiab muaj.

Rau US/European Projects:XaivSIB 304(ASTM 304) rau North American / European lag luam.

Rau feem ntau siv:Txij li thaum cov khoom sib pauv tau zoo sib xws, koj qhov kev xaiv feem ntau nyob ntawm qhov yooj yim nkag tau hauv koj cheeb tsam.
