Pain Point

17-7 PH (Precipitation Hardening) stainless hlau hypotubes yog dav siv nyob rau hauv siab -lub zog kho mob catheter xa tshuab, tab sis feem ntau cov tuam ntxhab tsis ua tiav nws cov khoom siv tshwj xeeb piv nrog cov pa 304 thiab 316L stainless hypotubes. Qhov teeb meem loj tshaj plaws ntawm kev tsim khoom yog nyob rau hauv nws cov khoom siv tsis ruaj khov tom qab ua tiav. Raws li ib nrab-austenitic nag lossis daus{11}}hardening alloy, 17-7 PH nta ua hauj lwm ceev ceev thaum lub sij hawm txias txias thiab laser ua, ua rau tsis sib xws hardness faib thoob plaws lub cev hypotube. Ntau lub chaw tsim khoom siv cov txheej txheem kev ua cov hlau tsis zoo rau 17-7 PH hypotubes, ua rau muaj kev ntxhov siab ntau dhau, micro- pib tawg thiab tsis sib haum lub zog tensile. Hauv kev siv tshuaj kho mob, qhov tsis zoo 17-7 PH hypotubes pom qhov tsis sib xws ntawm kev ua haujlwm: ultra-lub zog tensile siab txhim kho catheter pushability thiab torque kis tau tus mob, thaum cov khoom siv tsis zoo hauv lub xeev hloov ua rau tsis zoo kink tsis kam thiab cov kev pheej hmoo tawg hauv zos. Tsis tas li ntawd, 17-7 PH alloy muaj cov txheej txheem nag lossis daus ntawm txhuas, uas yog qhov ua rau oxidation thiab intergranular defects thaum laser txiav thiab thermal ua. Cov txheej txheem kev kho saum npoo rau cov hlau tsis zoo tib yam tsis tuaj yeem tshem tawm micro precipitates ntawm 17-7 PH qhov chaw, tawm hauv qhov tsis txaus ntshai thrombogenic. Batch-to-batch variation yog lwm qhov teeb meem tseem ceeb. Uncontrolled solution annealing and aging treatment of raw tubing leads to fluctuating hardness and fatigue resistance, ua unstable penetration force thiab shortened service life of tiav laser-cut hypotube assemblies. Cov khoom siv tshwj xeeb no ua rau cov khoom seem nce ntxiv, cuam tshuam cov txheej txheem ISO13485 validation thiab txwv tsis pub loj-scale daim ntawv thov ntawm 17-7 PH hypotubes nyob rau hauv high-precision interventional cov cuab yeej kho mob.

Txoj Cai

Lub hauv paus ntsiab lus tseem ceeb ntawm 17-7 PH hypotube cov ntaub ntawv kev ua tau zoo yog nyob rau hauv nag lossis daus hardening theem transformation thiab tswj microstructure hloov. Ua los ntawm 17% chromium, 7% npib tsib xee thiab kab txhuas cov ntsiab lus, 17-7 PH stainless hlau ua tiav ultra- siab zog los ntawm nano- nplai intermetallic precipitate nag lossis daus tom qab kev kho mob thiab kev laus tempering. Tsis zoo li austenitic 304/316L stainless hlau cia siab rau kev ua haujlwm txias txias, 17-7 PH paub txog lub zog hloov dua siab tshiab ntawm cov cua sov los ntawm theem nag lossis daus, sib npaug siab hardness thiab qee qhov ductility rau kev kho mob hypotube dabtsi yog khoov thiab torsion xav tau. Nyob rau hauv lub xeev annealed, 17-7 PH khaws cia zoo heev formability, cia precision raj kos duab thiab laser qauv; Tom qab kev laus hardening, nws lub zog tensile muaj peev xwm tshaj 1600MPa, deb superior rau zoo tib yam kev kho mob stainless hlau, muab superior pushability thiab cov qauv stability rau catheter xa tshuab. Txawm li cas los xij, lub zog los nag kuj tseem coj cov yam ntxwv ntawm cov khoom txwv: kev ua haujlwm txias ntau dhau ua ntej kev laus yuav rhuav tshem cov txheej txheem precipitate faib, ua rau cov kev ntxhov siab hauv zos thiab nkig nyiam. Lub alloy qhov corrosion kuj yog sib npaug rau 304 stainless hlau, tab sis deg precipitate inclusions txo qhov sib xws ntawm qhov chaw. Rau laser-txiav hypotubes, cov khoom siv tshwj xeeb ua haujlwm hardening tus nqi thiab thermal rhiab heev txiav txim siab tias txhua yam kev ua haujlwm suav nrog kev txiav, sib tsoo thiab ua tiav yuav tsum tau ua kom zoo ntawm nws tus kheej, tsis yog luam cov txheej txheem stainless hlau. Kev sib piv ntawm cov khoom siv hauv lub xeev thiab kev siv thev naus laus zis yog lub hauv paus rau kev siv lub zog zoo ntawm 17-7 PH hypotubes thaum tsis txhob muaj kev pheej hmoo ntawm kev ua haujlwm tsis zoo.
