1.4301 vs . 1.4306 Stainless hlau: Qhov txawv ntawm qhov tseem ceeb

Yog tias koj xaiv ntawm EN 1.4301 thiab EN 1.4306 stainless hlau, nkag siab txog lawv cov tshuaj muaj pes tsawg leeg, kev tiv thaiv corrosion, thiab daim ntawv thov tsim nyog yog qhov tseem ceeb rau kev txiav txim siab yuav khoom. Ob qib muaj nyob rau hauv austenitic 18/8 stainless hlau tsev neeg, sib npaug rau AISI 304 thiab AISI 304L, tab sis lawv txawv feem ntau ntawm cov ntsiab lus carbon thiab weldability kev ua tau zoo.1.4306 muaj cov ntsiab lus qis dua (0.03% max) dua li 1.4301 (0.07% corrosion kuj thiab max.)

 

X5CrNi18-10, 1.4301, AISI 304 yog dab tsi?
1.4301 stainless hlau yog sib npaug rau AISI 304 (tseem hu ua UNS S30400). Raws li European qauv, nws tseem hu ua X5CrNi18-10. Vim nws cov nominal muaj pes tsawg leeg ntawm 18% chromium thiab 8% npib tsib xee, qee zaum nws raug xa mus los ntawm nws lub npe laus, 18/8. Nws tuaj yeem ua tiav rau hauv ntau yam khoom siv, nrog rau cov phaj, coils, kav, tuav, thiab xaim.

 

1.4306 X2CrNi19-11 yog dab tsi?
Acid resistant stainless hlau nrog ntxiv ntawm nitrogen, txo cov ntsiab lus carbon thiab nce chromium 18-20% thiab npib tsib xee 10-12%. Txwv tsis pub, qhov kev txhim kho ntawm qib 1.4307 / AISI 304L. Siv qhov twg ib txwm 304 lossis 304L cov khoom tsis txaus thiab yuav tsum muaj kev tiv thaiv corrosion ntxiv.

 

1.4301 puas tuaj yeem siv 1.4306?
Yog lawm, tab sis yog tias vuam koom nrog lossis cov khoom siv yuav ua haujlwm nyob rau hauv ib puag ncig corrosive (tshwj xeeb tshaj yog cov tshuaj chloride lossis acid raug), 1.4306 raug pom zoo.
