PH15-7Mo Stainless hlau
PH15-7Mo stainless hlau, tseem hu ua 15-7 PH, yog cov hlau tsis muaj zog. Lub npe "15-7" nyob rau hauv lub npe hais txog cov hlau muaj pes tsawg leeg, uas yog 15 feem pua chromium thiab 7 feem pua nickel, thiab "PH" txhais tau tias cov hlau tuaj yeem ntxiv dag zog los ntawm nag lossis daus hardening. Qhov no suav nrog cua sov thiab txias cov khoom siv los tsim cov nplej zoo hauv cov hlau ua haujlwm, txhim kho nws lub zog thiab hardness. Nws yog chromium, nickel, thiab molybdenum-muaj martensitic nag lossis daus-hardening stainless hlau. PH15-7Mo stainless hlau muaj cov yam ntxwv tshwj xeeb xws li lub zog siab, hardness, thiab toughness, nrog rau zoo corrosion kuj, thiab nws lub zog ntau outperforms ntawm austenitic stainless hlau.
Los nag-hardening stainless hlau, tsis zoo li austenite ua hauj lwm hardening, muaj ib tug tsawg nickel cov ntsiab lus thiab muaj peev xwm tsim unstable austenite los yog martensite tom qab kev kho cua sov. Tom qab ntawd nws dhau mus kho kev laus kom precipitate intermetallic compounds (xws li Ni3Al) uas ntxiv dag zog rau cov hlau. Tom qab ntxiv dag zog, lub zog tensile tuaj yeem ncav cuag 1250-1600 MPa. Tsis tas li ntawd, PH15-7Mo tuaj yeem ua haujlwm hauv cov ntawv thov kub; Tom qab kev kho cua sov, nws tuaj yeem muab cov khoom zoo ntawm 482 degree.
