304 Stainless Hlau Thiab 201 Stainless Hlau Uas Zoo? Qhov txawv yog dab tsi?

304 stainless hlau thiab 201 stainless hlau uas zoo? Qhov txawv li cas?

201 xeb tiv taus, thiab tsis tuaj yeem siv rau cov tais diav hauv chav ua noj, 304 dav siv, yog cov zaub mov qib stainless hlau.

304 stainless hlau yog ib hom universal stainless hlau khoom, xeb kuj muaj zog tshaj 200 series ntawm stainless hlau khoom, resistant rau 600 degrees kub. Nws muaj zoo heev corrosion kuj thiab zoo kuj rau intergranular corrosion. Nws kuj muaj qhov zoo corrosion kuj rau alkaline daws thiab feem ntau cov organic thiab inorganic acids.

304 stainless hlau thiab 201 stainless hlau:

Ua ntej, 201 yog ib feem ntawm Ni steel, 301 steel hloov steel. Sib nqus tom qab ua haujlwm txias, siv hauv tsheb ciav hlau.

Thib ob, 304 yog cov khoom siv dav siv stainless hlau, cov hlau tsis muaj cua sov. Siv rau hauv cov khoom siv khoom noj khoom haus, khoom siv tshuaj lom neeg Xitong, nuclear zog, thiab lwm yam.

Thib peb, 201 yog siab nyob rau hauv manganese cov ntsiab lus, qhov saum npoo yog ci heev nrog tsaus ci, thiab siab manganese cov ntsiab lus yog yooj yim rau xeb.

Plaub, 304 muaj ntau chromium, nto yog matte, tsis muaj xeb. Muab ob qho tib si ua ke thiab muaj kev sib piv. Qhov tseem ceeb tshaj plaws yog qhov kev tiv thaiv corrosion yog qhov sib txawv, corrosion kuj ntawm 201 yog qhov tsis zoo, yog li tus nqi yuav pheej yig dua. Thiab vim tias 201 muaj cov npib tsib xee tsawg, yog li tus nqi qis dua 304, yog li qhov corrosion kuj tsis zoo li 304.
