Dab tsi yog los nag lossis dab tsi ua kom tawv tawv tawv tawv tawv tawv tawv tawv tawv tawv tawv tawv tawv tawv tawv tawv tawv tawv tawv tawv
Zes nag lossis daus, feem ntau hu ua "Ph pali stainless uas undergitation tawv nqaij tawv lossis hnub nyoog tawv. Qhov txheej txheem no txhim kho cov khoom siv tshuab ntawm cov khoom, tshwj xeeb nws muaj zog thiab hardness. Cov neeg siv daus ntau tshaj plaws nag lossis daus ua kom tawv tawv17-4 PH(Astm A705 Qib 630), tab sis lwm cov qib, tab sis 13-5 pH thiab 13-8 EH Qhov sib ntxiv ntawm cov ntsiab lus sib ntxiv no txhawb kev tsim ntawm kev tsim los nag thaum lub sijhawm kho kom sov.
Yuav ua li cas yog stainless hlau los daus tawv tawv?
Lub hnub nyoog ua kom tawv stainless hlau cuam tshuam nrog peb-kauj ruam txheej txheem. Thaum pib, cov ntaub ntawv undergoes kev kho kub siab, qhov twg solution atoms abs, sib haum ib-theem kev daws teeb meem. Qhov no ua rau muaj kev tsim ntawm ntau lub tshuab tsom meico lossis "thaj chaw" ntawm cov hlau. Tom qab, sai sai tshwm sim tshaj lub solubility txwv, tsim cov supersaturated cov tshuaj hauv lub teeb meem yog rhuab rau ib qho kub thiab dej nag. Cov ntaub ntawv tau muab khaws cia rau hauv lub xeev no kom txog thaum nws tsis tawv nqaij tawv. Kev vam meej hnub nyoog ua kom tiav yuav tsum tau muaj ntau yam sib xyaw ua ke los ua kev txwv solubility, kom ua tau zoo ntawm cov txheej txheem.
Dab tsi yog cov hom twg los nag lossis tawv tawv tawv?
Nas hau kev nyuaj siab - cov hlau hardening tuaj hauv ntau hom, txhua tus neeg ua kom tau raws li kev ua tau zoo thiab kev siv tau. Hom ntau yam suav nrog 17-4, 15-5 EH, 13-8 PH, 16-7 PH, A-286, Nchuav 450, kev cai 630 (17-4 PHMOD), thiab cov ntoo kab lis kev cai 455. Cov hlau no muaj kev sib xyaw ua ke ntawm kev lag luam siab, ua rau lawv haum rau kev sib txawv xws li aerospace, kho mob, thiab ua haujlwm siv tshuaj. Kev xaiv ntawm nag lossis daus-tawv steel nyob ntawm cov xwm txheej xws li kev thov ib puag ncig, kev ua tau zoo, thiab kev tsim cov ntaub ntawv tshwj xeeb.
