Puas martensitic stainless hlau xeb?

Date:May 29, 2019

Maraging stainless hlau yuav yeej xeb, thiaj li hu ua stainless hlau tsuas yog nws cov kev txhim kho corrosion yog zoo dua, tsis yooj yim yuav xeb.

1cr13, 2cr13, sib npaug rau 410420 steel. Hauv cov hlau nquag, 4 series ntawm cov hlau tsis yog stainless hlau hauv kev nkag siab zoo, tab sis maraging Ferric stainless hlau, uas tuaj yeem tsuas yog hu ua stainless hlau zoo tshaj. Yog li ntawd, nws txoj kev txhim kho corrosion yog qhov tsawg heev, nws tsis tuaj yeem sib piv nrog 2 series, 3 series stainless hlau.

2 series stainless hlau, xws li 202204, nws cov npib tsib xee ntsiab lus yog tsawg, tus nqi yog pheej yig, tab sis qhov kev ua tau zoo tag nrho, tsis hais xeb tawm tsam lossis tsis muaj zog, nws tsis zoo dua li 3 series.

3 series stainless hlau, tuaj yeem dhau los ua stainless hlau hauv qhov kev nkag siab tiag, nws qhov kev txhim kho corrosion yog qhov zoo dua li lwm cov qauv, tshwj xeeb tshaj yog 304 qib stainless hlau muaj cov khoom zoo dua. Tab sis txawm tias 3 series stainless hlau yuav tseem corroded hauv ib puag ncig. Piv txwv li, 304 tuaj yeem xyuas kom meej tias nws tsis xeb rau ntau dua 5 xyoos hauv qhov chaw nyob zoo, tab sis kev ntsuam xyuas ntsev txau, nws nyuaj rau 168 teev (7 hnub). Yog tias 304 hla dhau, nws tuaj yeem ntev li 720 teev (30 hnub) hauv kev ntsuas tshuaj ntsev, tab sis nws kuj nyuaj rau lub sijhawm ntev dua.

Yog li ntawd, txhua hom hlau stainless yog qhov txheeb ze, raws li qhov muaj tseeb ib puag ncig thiab cov sijhawm rau kev txiav txim siab seb cov hlau twg xaiv. Tom qab txhua tus, tus nqi ntawm high-specification stainless hlau yog ntau kim tshaj li lwm qib, thiab txawm suav los ntawm cov lej.

Ntxiv rau, 1cr18ni9ti, sib npaug nrog 321 (sib txawv me ntsis), yog ib qib siab tshaj plaws hauv cov koob 3, yog Austenite stainless hlau, thiab tiv rau qhov kub thiab txias. Nws lub cev lub zog yog zoo heev, txawm tias nws yog lub zog lossis corrosion tsis kam. Hauv thaj chaw ib puag ncig zoo, nws tsis yooj yim los ua 1cr18ni9ti xeb.
