Cov Hlau Stainless Hlau Uas Muaj Hnub Nyoog Uas Ua Rau Ruaj Khoov
Kev Piav Qhia Luv:
Kev ua kom tawv thaum laus, tseem hu ua kev ua kom tawv thaum nag los, yog ib txoj kev kho cua sov uas ua rau lub zog thiab qhov tawv ntawm qee cov hlau sib xyaw, suav nrog cov hlau tsis xeb. Lub hom phiaj ntawm kev ua kom tawv thaum laus yog ua kom cov khoom me me hauv cov hlau tsis xeb poob rau hauv, uas ua rau cov khoom siv muaj zog.
Cov Hlau Stainless Steel Forgings Bar Uas Muaj Hnub Nyoog:
Cov khoom forging yog cov khoom hlau uas tau tsim los ntawm cov txheej txheem forging, qhov twg cov khoom siv tau cua sov thiab tom qab ntawd hammered lossis nias rau hauv daim ntawv xav tau. Cov hlau stainless hlau forgings feem ntau raug xaiv rau lawv qhov kev tiv thaiv corrosion, lub zog, thiab durability, ua rau lawv haum rau ntau yam kev siv, suav nrog aerospace, roj thiab roj, thiab ntau ntxiv. Ib qho bar-puab forging yog ib daim ntawv tshwj xeeb ntawm cov hlau forged uas feem ntau muaj lub duab ntev, ncaj, zoo ib yam li ib tug bar lossis pas nrig. Cov bars feem ntau siv rau hauv cov ntawv thov uas xav tau ib tug tas mus li, ncaj ntev ntawm cov khoom siv, xws li nyob rau hauv kev tsim kho ntawm cov qauv lossis ua raw khoom rau kev ua ntxiv.

Dab tsi yog Precipitation Hardening Stainless Steel?
Cov hlau tsis xeb uas ua kom tawv thaum nag los, feem ntau hu ua "PH stainless steel," yog ib hom hlau tsis xeb uas dhau los ntawm cov txheej txheem hu ua precipitation hardening lossis age hardening. Cov txheej txheem no ua rau cov khoom siv kho tshuab ntawm cov khoom siv zoo dua, tshwj xeeb tshaj yog nws lub zog thiab qhov nyuaj. Cov hlau tsis xeb uas ua kom tawv thaum nag los feem ntau yog17-4 PH(ASTM A705 Qib 630), tab sis lwm qib, xws li 15-5 PH thiab 13-8 PH, kuj poob rau hauv pawg no. Cov hlau tsis xeb uas ua kom tawv thaum nag los feem ntau yog sib xyaw nrog cov ntsiab lus xws li chromium, nickel, tooj liab, thiab qee zaum txhuas. Kev ntxiv cov ntsiab lus sib xyaw no txhawb nqa kev tsim cov precipitates thaum lub sijhawm kho cua sov.
Yuav ua li cas cov hlau tsis xeb thiaj li tawv?
Kev ua kom cov hlau stainless hlau khov kho muaj peb kauj ruam. Thaum xub thawj, cov khoom siv yuav raug kho nrog qhov kub siab, qhov twg cov solute atoms yaj, tsim cov tshuaj ib theem. Qhov no ua rau muaj ntau lub nuclei me me lossis "zones" ntawm cov hlau. Tom qab ntawd, txias sai sai tshwm sim dhau qhov txwv solubility, tsim cov tshuaj khov supersaturated hauv lub xeev metastable. Hauv kauj ruam kawg, cov tshuaj supersaturated raug cua sov rau qhov kub nruab nrab, ua rau muaj nag. Cov khoom siv ces khaws cia rau hauv lub xeev no kom txog thaum nws khov. Kev ua kom cov hlau alloy khov kho zoo yuav tsum tau ua kom cov khoom sib xyaw ua ke nyob hauv qhov txwv solubility, kom ntseeg tau tias cov txheej txheem ua haujlwm tau zoo.
Cov hlau uas tau los ntawm kev sib tsoo thiab tawv yog dab tsi?
Cov hlau uas ua rau nag los thiab tawv muaj ntau hom, txhua hom raug tsim los kom ua tau raws li qhov xav tau ntawm kev ua tau zoo thiab kev siv. Cov hom hlau feem ntau suav nrog 17-4 PH, 15-5 PH, 13-8 PH, 17-7 PH, A-286, Custom 450, Custom 630 (17-4 PHMod), thiab Carpenter Custom 455. Cov hlau no muaj kev sib xyaw ua ke ntawm lub zog siab, kev tiv thaiv corrosion, thiab qhov nyuaj, ua rau lawv haum rau ntau yam lag luam xws li aerospace, automotive, kev kho mob, thiab kev ua tshuaj lom neeg. Kev xaiv cov hlau uas ua kom cov nag lossis daus-tawv nyob ntawm cov yam xws li ib puag ncig ntawm daim ntawv thov, kev ua tau zoo ntawm cov khoom siv, thiab cov lus qhia tsim khoom.
