17-4 PH annealed stainless hlau ntawv
Tso lus
17-4 PH stainless hlau phajyog martensitic nag lossis daus- hardening stainless hlau, los yog SUS630 los yog UNS S17400. Annealed 17-4 PH stainless hlau phaj yog hais txog 17-4 PH stainless hlau phaj uas tau dhau los ua cov tshuaj annealing kub kho, ua ib qho kev kho ua ntej ua ntej lub hnub nyoog kawg hardening. Nws tseem hu ua 17-4PH Condition A.
Kev daws annealing feem ntau yog ua los ntawm 1020-1060℃tom qab txias txias, uas tswj cov hardness hauv qab 38 HRC (tsawg dua lossis sib npaug rau 363 HB). Qhov no muab cov machinability zoo heev, ua rau nws yooj yim rau txiav thiab daim ntawv. Nws qhov kev tiv thaiv corrosion yog ze rau ntawm 304 stainless hlau, tso cai rau nws hloov mus rau cov kev ua haujlwm thiab chaw cia khoom.
Tom qab tom qab qis- qhov kub ntawm lub hnub nyoog hardening kev kho mob (nrog rau kev laus kub adjustable ntawm 480℃thiab 620 degree), nws tensile lub zog muaj peev xwm ncav cuag 930-1310 MPa kom tau raws li ntau yam kev thov, thaum tswj qhov tsawg kawg nkaus deformation ncej- kho cua sov.
Vim nws qhov yooj yim ntawm kev ua haujlwm thib ob, annealed 17-4 PH steel daim hlau yog siv rau kev cai machining ntawm ntau yam qauv, xws li aerospace cav brackets, tshuaj valve cores, kev kho mob cov cuab yeej, roj av kev lag luam valve stems, thiab lwm yam uas yuav tsum tau muaj zog thiab corrosion kuj.
Cov qauv rau 17-4 PH Annealed Sheet
ASTM A693: Tus qauv qhia tshwj xeeb rau nag- ua kom cov hlau tsis muaj zog cua sov- cov nplooj ntawv, daim hlau, thiab strips (feem ntau siv).
AMS 5604: Aerospace cov ntaub ntawv tus qauv (rau cov ntawv hlau).

FAQ
Dab tsi yog qhov txawv ntawm 17-4 PH thiab 17-7 PH stainless hlau?
17-4 PH stainless hlau muaj qhov hardness siab heev, rigidity, thiab zoo weldability. Nws yog feem ntau yog siv rau hauv cov khoom siv, cov khoom siv hauv aerospace, tsav shafts, fasteners, thiab cov cuab yeej kho mob.
17-7 PH stainless hlau nthuav tawm ntau dua ductility hauv lub xeev annealed, ua kom yooj yim khoov rau hauv cov duab nyuaj. Nws yog cov khoom siv zoo tshaj plaws rau cov springs, bellows, diaphragms, thiab cov khoom raug rov kho dua thiab kev ntxhov siab.
17-4 PH daim ntawv nyob rau hauv lub xeev annealed yuav khoov los yog txias-tsim?
Kev pom zoo: Lub vojvoog dabtsi yog khoov yuav tsum loj npaum li qhov ua tau. Yog xav tau kev sib sib zog nqus los yog ua kom muaj zog, 17-7 PH feem ntau pom zoo vim nws yog softer (austenitic qauv) nyob rau hauv lub xeev annealed thiab yooj yim rau daim ntawv.
