Stainless Hlau Coils

Khoom Taw Qhia:

Stainless hlau txhais tau tias yog stainless, corrosion kuj raws li cov yam ntxwv tseem ceeb, thiab cov ntsiab lus chromium tsawg kawg yog 10.5 feem pua, cov ntsiab lus carbon txog li 1.2 feem pua ​​raws li GB/T20878-2007.

Stainless hlau yog lub ntsiab lus ntawm stainless acid-resistant steel, resistant rau huab cua, chav, dej thiab lwm yam tsis muaj zog corrosive media los yog stainless yog hu ua stainless hlau los xij; Cov hlau uas tiv taus cov tshuaj tiv thaiv corrosion media (acid, alkali, ntsev thiab lwm yam tshuaj yaig) yog hu ua acid-resistant steel. Hauv qab no yog stainless hlau coils:

Vim qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg ntawm ob thiab lawv qhov sib txawv corrosion kuj, cov nplooj ntawv stainless hlau zoo tib yam feem ntau tsis tiv taus tshuaj corrosion, thaum acid-resistant steel feem ntau stainless hlau. Lub sij hawm "stainless steel" tsis yog tsuas yog xa mus rau ib hom stainless hlau, tab sis rau ntau tshaj li ib puas industrial stainless steels, txhua tus tsim nrog cov khoom zoo hauv nws qhov tshwj xeeb daim ntawv thov. Tus yuam sij rau kev vam meej yog thawj zaug kom paub txog lub hom phiaj thiab tom qab ntawd txiav txim siab qib zoo. Muaj feem ntau tsuas yog rau qib steel uas muaj feem xyuam rau kev siv lub tsev. Lawv tag nrho muaj 17 ~ 22 feem pua ​​​​chromium, thiab cov qib hlau zoo dua kuj muaj cov npib tsib xee. Qhov sib ntxiv ntawm molybdenum tuaj yeem txhim kho atmospheric corrosion, tshwj xeeb tshaj yog tsis kam mus rau chloride-muaj cua.

Feem ntau, lub hardness ntawm stainless hlau yog siab dua li ntawm aluminium alloy, thiab tus nqi ntawm stainless hlau yog siab dua li ntawm aluminium alloy.

Cov yam ntxwv tseem ceeb:

1. Corrosion kuj

Feem ntau ntawm cov ntaub ntawv stainless hlau cov khoom yuav tsum tau zoo corrosion kuj, xws li thawj- thiab thib ob-class tableware, kitchenware, dej rhaub, dej dispensers, thiab lwm yam., ib co txawv teb chaws businessmen kuj ua corrosion kuj rau cov khoom: siv NaCl aqueous tov. kom sov kom npau npau, tom qab ib lub sij hawm ntawm lub sij hawm ncuav lub tov, ntxuav thiab qhuav, hnyav qhov poob, los txiav txim siab qhov degree ntawm corrosion (ceeb toom: thaum cov khoom yog polished, vim hais tias cov emery ntaub los yog sandpaper muaj Fe, uas yuav ua rau xeb. qhov chaw ntawm qhov chaw thaum kuaj).

2. Polishing kev ua tau zoo

Nyob rau hauv lub neej niaj hnub no, stainless hlau daim hlau cov khoom yog feem ntau polished thaum lub sij hawm tsim khoom, thiab tsuas yog ob peb yam khoom xws li lub rhaub dej thiab cov dej dispenser tsis tas yuav polished. Yog li ntawd, qhov no yuav tsum tau hais tias polishing kev ua tau zoo ntawm raw khoom yog zoo heev.

3. Thaum tshav kub kub tsis kam

Thaum tshav kub kub tsis kam txhais tau hais tias stainless hlau tseem tuaj yeem tswj nws lub cev zoo thiab cov khoom siv kho tshuab ntawm qhov kub thiab txias.

Cov nyhuv ntawm cov pa roj carbon: Cov pa roj carbon monoxide yog cov khoom siv hauv austenitic stainless hlau uas muaj zog tsim thiab ruaj khov austenite thiab nthuav dav thaj tsam austenitic. Carbon yog kwv yees li 30 npaug ntau lub peev xwm ntawm kev tsim austenite tshaj npib tsib xee, qhov sib txawv uas tuaj yeem ua kom muaj zog ntawm austenitic stainless hlau los ntawm kev daws teeb meem. Cov pa roj carbon kuj tseem txhim kho cov kev ntxhov siab thiab kev tiv thaiv corrosion ntawm austenitic stainless hlau los xij hauv cov tshuaj chlorides xws li 42 feem pua ​​​​MgCl2 boiling tov.

4. Corrosion kuj

Thaum tus naj npawb ntawm chromium atoms nyob rau hauv cov hlau tsis tsawg tshaj li 12.5 feem pua, cov electrode muaj peev xwm ntawm hlau tuaj yeem hloov tau, thiab cov peev xwm tsis zoo tuaj yeem raug tsa mus rau qhov zoo electrode muaj peev xwm. Tiv thaivgalvanic corrosion kuj.

Daim ntawv thov:

Siv dav hauv kev tsim kho thiab kho kom zoo nkauj, khoom siv kho mob, khoom noj khoom haus hauv chav ua noj, khoom noj khoom haus, khoom noj khoom haus, ntim, precision electronics, rail transit, machinery manufacturing, chemical equipment and other fields.
