JIS G4305: 2015 Txwv cov ntsiab lus siab tshaj plaws hauv Sus304 Stainless Hlau Hloov Chaw rau 0.045%. Phosphorus yog cov khoom seem ntawm steelmaking, tab sis qib siab muaj ob qho tseem ceeb tsis txaus ntseeg:
Brittleness: Phosphorus segregates ntawm cov ciaj ciam nplej, tsis muaj zog intergranur interglanular bonds thiab nce kev pheej hmoo ntawm brittle bacite, tshwj xeeb yog thaum kub tsawg.
Corrosion Kev Ua Phem: Tshaj phosphorus txo kev tawm tsam kom pitting corrosion hauv cosphorus ib puag ncig thiab ntiav {3/pob kev ua kom siab raw khoom thiab ua haujlwm meatalurgy cov txheej txheem kom tshem tawm impurities. Post -}} production, txhua pob tau sim rau cov tshuaj muaj tshuaj lom neeg, nrog cov lej phosphorus teev hauv cov ntaub ntawv pov thawj. Lub 0.045% CAP ua kom meej meej sus304 tswj hwm nws txoj kev dog thiab corrosion tsis kam, ua rau nws tsim nyog siv cov ntawv thov kho vajtse lossis tshuaj lom neeg.
