Austenitic stainless steels tsis tuaj yeem tawv los ntawm kev kho cua sov. Hloov chaw, cov hlau no ua haujlwm tawv (lawv muaj hardness thaum lawv tsim thiab tsim). Annealing cov stainless steels softens lawv, ntxiv ductility thiab imparts txhim kho corrosion kuj.
Nws puas muaj kev nyab xeeb rau cov hlau tsis huv?
Feem ntau cov lauj kaub hlau tsis muaj hlau thiab cov lauj kaub yog txhais tau tias yuav tsum tau siv ntawm cua sov nruab nrab thiab cov txheej txheem tuaj yeem tiv taus txog 500 lossis 600 degrees Fahrenheit.
Yuav ua li cas yog tias koj rhaub stainless hlau?
Lub tshav kub raug cuam tshuam (HAZ) thaum lub sij hawm vuam los yog thermal txiavtxheej txheem loj dua ntawm cov hlau tsis muaj steel vim tias qis dua thermal diffusivity (4.2 mm2 / s) piv rau lwm yam hlau. Qhov no tuaj yeem ua rau muaj kev hloov pauv hauv qib (austenitic stainless hlau tig martensitic, nkig thiab tawv dua) lossis cov hlau rhuab yuav tsis muaj zog.
Puas stainless hlau tuaj yeem ua kom sov?
Ib qho ntawm cov khoom tseem ceeb ntawm cov hlau tsis muaj steel hlau yog nws tsis kam oxidation. … Hauv lwm lo lus, koj tuaj yeem nthuav tawm qib 304 alloy steel rau kub txog li 1, 598 ° F rau lub sijhawm luv luv yam tsis muaj kev mob tshwm sim, thiab rau lub sijhawm ntev ntawm qhov kub thiab txias. rau 1,697 °F.
Puas yog stainless hlau thaum tshav kub kub resistant?
Stainless steel muaj lub zog zoo thiab zoo tiv thaiv corrosion thiab oxidation ntawm qhov kub siabStainless hlau yog siv kub txog li 1700 ° F rau 304 thiab 316 thiab mus txog 2000 F rau qhov kub siab stainless qib 309(S) thiab mus txog 2100 ° F rau 310(S).
