Basic Carbon Steel Khoom
Cov pa roj carbon zoo rau cov tsheb ciav hlau muaj xws li Q235 thiab 45 # steel. Q235 yog ib qho qis- carbon steel nrog zoo plasticity thiab weldability, thiab kuj yog pheej yig, haum rau cov tsheb ciav hlau zoo tib yam uas yuav tsum tau muaj zog tsis siab siab . 45# steel yog nruab nrab - carbon steel; nws cov tawv tawv thiab hnav tsis kam tuaj yeem txhim kho tau zoo los ntawm kev kho cua sov, thiab nws feem ntau yog siv hauv nruab nrab - thiab qis - tsheb ciav hlau ceev lossis tsheb thauj khoom thauj, ua tau raws li kev xav tau kev thauj mus los yooj yim.
Cov khoom siv hlau alloy
Txhawm rau hloov mus rau qhov hnyav xws li kev kub ceev thiab hnyav, tsheb ciav hlau log dav siv hlau alloy, nrog rau cov qauv xws li 42CrMo thiab 50CrMo4. Cov hlau no, los ntawm kev ntxiv cov ntsiab lus alloying xws li chromium (Cr) thiab molybdenum (Mo), ua kom cov khoom siv zog, tawv, thiab qaug zog. Ntawm lawv, 42CrMo muaj lub zog siab thiab zoo hardenability, haum rau siab - tsheb ciav hlau ceev; 50CrMo4 muaj qhov sib piv ntxiv ntawm cov alloy thiab feem ntau siv rau hauv hnyav - tsheb thauj khoom thauj, tiv thaiv kev sib txhuam hnyav thiab cuam tshuam ntawm lub log thiab tsheb ciav hlau.
Stainless hlau rau kev ua haujlwm tshwj xeeb
Nyob rau hauv cov av noo, ntsev tsuag, los yog tshuaj corrosive ib puag ncig (xws li cov ntug hiav txwv railways thiab tshuaj cog kab), tsheb ciav hlau log yog ua los ntawm 2205 duplex stainless hlau. Nws qhov tshwj xeeb chromium (Cr) thiab molybdenum (Mo) piv (Cr cov ntsiab lus 21% -23%, Mo cov ntsiab lus 2.5% -3.5%) muab cov khoom siv ob qho tib si lub zog ntawm austenitic stainless hlau thiab lub zog ntawm ferritic stainless hlau, thaum tseem muab kev tiv thaiv zoo heev rau pitting thiab crevice corrosion, ua rau lub neej ntev kev pab cuam ntawm lub log nyob rau hauv corrosive.
