SS 201 vs 304: Dab tsi yog qhov txawv?

Qhov sib txawv ntawm qhov sib txawv:
Cov tshuaj formula ntawm 201 stainless hlau yog 1Cr17Mn6Ni5, uas muaj qis nickel thiab siab dua manganese.
Cov tshuaj formula ntawm304 stainless hlauyog 06Cr19Ni10, uas muaj ntau dua nickel thiab qis manganese.
Corrosion kuj:
Vim yog cov ntsiab lus qis nickel, 201 stainless hlau tsis yog corrosion-resistant li 304 stainless hlau, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm acid thiab alkali tsis kam.
Vim yog cov ntsiab lus nickel ntau dua, 304 stainless hlau muaj kev tiv thaiv corrosion zoo dua thiab tsis yooj yim rau xeb.
Xim txawv:
Vim muaj cov ntsiab lus ntawm manganese ntau dua, 201 stainless hlau muaj qhov ci thiab tsaus me ntsis.
304 stainless hlau muaj ntau chromium thiab muaj matte nto.
Compression tsis kam:
Cov ntsiab lus carbon ntawm 201 stainless hlau yog siab dua, yog li nws nyuaj dua tab sis nkig ntau dua. Scratching nws nto nrog ib yam khoom nyuaj yuav ua rau pom tseeb khawb.
304 stainless hlau muaj qhov toughness zoo dua thiab cov khawb tsis pom tseeb.
