Stainless hlau: 4 hom tseem ceeb

Stainless hlau: 4 hom tseem ceeb

Stainless hlau ' yog ib lub kaus uas npog ntau yam alloys. Yuav kom suav hais tias yog cov hlau tsis muaj hlau ib qho hlau-raws li alloy yuav tsum ua tau raws li ib qho kev ntsuas uas muaj qhov tsawg kawg nkaus ntawm 10.5% chromium. Kev sib txawv ntawm cov nyiaj no lossis ntxiv lwm yam khoom tsim tawm ntau hom stainless hlau, txhua tus muaj cov khoom sib txawv thiab kev siv.

Stainless-Steel-hlau

Feem ntau hais lus, txhua qhov kev hloov pauv ntawm cov hlau tsis muaj steel raug muab faib ua ib qho ntawm plaub pawg. Hauv tsab ntawv no ntawm peb cov blog, peb nthuav qhia luv luv rau cov pab pawg sib txawv.

AUSTENITIC. Cov pab pawg no muaj ntau hom stainless hlau. Austenitic stainless hlau muaj, piv rau lwm hom, cov ntsiab lus siab ntawm nickel, chromium, molybdenum thiab chromium. Renowned rau lawv cov qib siab ntawm malleability, lub zog thiab corrosion kuj, austenitic steels yog tshwj xeeb tshaj yog muaj ntau yam nrog ntau txhiab daim ntawv thov.
FERRITIC. Cov pa roj carbon zoo sib xws hauv ferritic stainless hlau yog tsawg, feem ntau tsis tshaj 0.1%. Feem ntau muaj cov chromium tab sis qee zaum nrog cov khoom ntxiv xws li molybdenum, ferritic stainless hlau yog cov hlau nplaum thiab tso saib zoo heev tiv thaiv kev ntxhov siab corrosion.
DUPLEX. Qhov tseem ceeb ntawm kev sib xyaw ua ke ntawm austenitic thiab ferritic stainless hlau, duplex muaj zog dua li ob qho tib si. Nws tseem tsis tshua muaj kev tiv thaiv corrosion, ua rau nws cov khoom ntawm kev xaiv rau ntau daim ntawv thov nyob rau hauv offshore roj thiab roj chaw.
MARTENSITIC. Txawm hais tias cov qauv zoo ib yam li ferritic stainless hlau, martensitic stainless hlau muaj ntau cov pa roj carbon ntau (ze li 1%). Qhov sib txawv ntawm cov pa roj carbon feem pua ​​no ua rau muaj qhov sib txawv ntawm qhov tseem ceeb: martensitic stainless hlau tuaj yeem hardened mus rau qib loj, imbuing lawv muaj zog heev.
