Qhov txawv ntawm 201 tsis-magnetic stainless hlau thiab 304
Txawv sib txawv
201 stainless hlau muaj 15% chromium thiab 5% npib tsib xee. Standard 304 stainless hlau, muaj 18% chromium thiab 9% npib tsib xee. Kev tiv thaiv corrosion sib txawv: 201 muaj cov ntsiab lus siab manganese thiab ci ntsa iab, tab sis nws yooj yim rau xeb. 304 muaj ntau cov chromium, muaj qhov dull nto, thiab tsis yooj yim rau xeb.
Qhov sib txawv ntawm 201 thiab 304 yog qhov teeb meem ntawm cov ntsiab lus nickel
Tus nqi ntawm 304 kuj tseem kim tam sim no, feem ntau yog ze rau 50000 ib tuj, tab sis 304 tsawg kawg tuaj yeem lav tias nws yuav tsis xeb thaum siv.Stainless steel tsis yooj yim rau xeb vim tias tsim cov chromium nplua nuj oxides ntawm cov hlau. tuaj yeem tiv thaiv cov hlau. 201 khoom belongs rau high manganese stainless hlau nrog hardness siab tshaj 304, siab carbon thiab tsawg npib tsib xee.
316 stainless hlau muaj zoo corrosion kuj
316 stainless steel has better corrosion resistance and almost no metal ion precipitation. It is commonly used as a medical material, but it is relatively expensive. The selection order is as follows: 316>18/10>304. Science popularization: Qee tus neeg feem ntau yuam kev 18/10 stainless hlau rau 316 stainless hlau, tab sis qhov tseeb, 18/10 stainless hlau belongs rau 304 stainless hlau, uas zoo sib xws hauv qib 316.
Txawv nto
Nyob rau saum npoo, 201 stainless hlau muaj xim npub, thaum 304 stainless hlau muaj qhov du thiab ci ntsa iab. Vim muaj cov khoom sib txawv, 201 stainless hlau muaj cov ntsiab lus manganese ntau dua, thiab thaum sib cuag nrog cov tshuaj acidic, manganese hauv nws yooj yim los nag. Rau 304 stainless hlau, npib tsib xee nyob rau hauv nws muaj pes tsawg leeg yog ib qho tseem ceeb heev, ncaj qha txiav txim nws corrosion kuj thiab tus nqi.
Feem ntau hais lus, cov khoom tsis sib nqus hlau tsis sib nqus yog xa mus rau cov hlau tsis muaj hlau uas, tom qab kev kho kev puas tsuaj, muaj cov nickel ntau ntau thiab tsis tuaj yeem sib nqus sab nraud.
