Stainless hlau yog renowned rau nws durability, corrosion kuj, thiab aesthetic thov. Txawm li cas los xij, tsis yog txhua tus hlau tuaj yeem thov cov npe "stainless" prefix. Ib qho tseem ceeb tshaj plaws uas txiav txim siab seb cov hlau puas tsim nyog li stainless yog cov ntsiab lus chromium.
Chromium plays lub luag haujlwm tseem ceeb hauv kev hloov cov hlau tsis tu ncua rau hauv stainless hlau. Yuav kom khwv tau lub npe stainless, steel yuav tsum muaj qhov tsawg kawg nkaus feem pua ntawm chromium. Feem ntau, stainless hlau yuav tsum muaj tsawg kawg yog 10.5% chromium cov ntsiab lus los tiv thaiv xeb tsim tau zoo. Qhov chaw pib no tsim lub hauv paus rau cov hlau tsis muaj corrosive, ua rau nws haum rau ntau yam kev siv.
Qhov sib ntxiv ntawm chromium rau hlau tsim ib txheej tiv thaiv oxide rau ntawm qhov chaw, hu ua passive txheej. Cov txheej no ua raws li cov ntaub thaiv tiv thaiv corrosive xws li ya raws thiab oxygen. Yog tias tsis muaj kev tiv thaiv kev tiv thaiv no, cov hlau yog qhov ua rau xeb thiab degradation. Los ntawm kev sib xyaw chromium, stainless hlau tau txais kev tiv thaiv zoo tshaj rau tarnishing, staining, thiab pitting, kom ntseeg tau ntev thiab kev ntseeg siab hauv ntau qhov chaw.
Tsis tas li ntawd, lub xub ntiag ntawm chromium txhim kho cov hlau lub zog thiab toughness. Cov khoom siv alloying no txhim kho cov hlau cov khoom siv kho tshuab, ua rau nws muaj zog dua thiab muaj zog dua piv rau cov qib steel. Lub synergy ntawm chromium thiab lwm yam alloying ntsiab refines lub microstructure ntawm stainless hlau, uas ua rau cov kev ua tau zoo cov yam ntxwv.
Hauv kev lag luam xws li kev ua zaub mov mus rau kev tsim kho, stainless hlau qhov tshwj xeeb zoo ua rau nws nyiam xaiv rau cov ntawv thov tseem ceeb. Lub peev xwm tiv taus cov xwm txheej hnyav, tswj cov qauv kev nyiam huv, thiab tiv thaiv cov tshuaj lom neeg ua rau pom qhov tseem ceeb ntawm chromium hauv stainless hlau ntau lawm. Txawm hais tias siv hauv cutlery, cov cuab yeej kho mob, cov qauv tsim vaj tsev, lossis cov khoom siv hauv aerospace, stainless hlau qhov kev siv ntau yam yog los ntawm nws cov chromium-enriched muaj pes tsawg leeg.
Hauv kev xaus, suav nrog qhov tsawg kawg nkaus ntawm chromium cov ntsiab lus ntawm 10.5% txawv stainless hlau los ntawm nws cov pa sib piv. Cov khoom siv alloying no txhawb nqa cov hlau nrog kev tiv thaiv corrosion, durability, thiab lub zog, muab nws sib nrug raws li cov khoom zoo rau ntau yam kev lag luam thiab hauv tsev. Lub fusion ntawm science thiab metallurgy nyob rau hauv stainless hlau ntau lawm underscores lub luag hauj lwm tseem ceeb ntawm chromium nyob rau hauv shaping niaj hnub engineering thiab tsim qauv.
