Austenitic nag lossis daus hardening steels khaws lawv cov qauv austenitic tom qab annealing thiab hardening los ntawm kev laus. Ntawm qhov kub thiab txias ntawm 1095 txog 1120 degree nag lossis daus hardening theem yog soluble. Nws tseem nyob rau hauv kev daws thaum lub sij hawm txias ceev. Thaum reheated rau 650 rau 760 degree, nag lossis daus tshwm sim. Qhov no nce hardness thiab lub zog ntawm cov khoom. Hardness tseem qis dua li rau martensitic lossis semi-austenitic nag lossis daus hardening steels. Austenitic alloys nyob twj ywm nonmagnetic.

Kuj hu ua Alloy 630, hom 17-4PH yog qhov siv dav tshaj plaws ntawm tag nrho cov nag lossis daus-hardening steels. Piv nrog rau lwm cov PH alloys, nws yuav tsum muaj kev kho cua sov yooj yim los tsim ntau yam khoom, nrog rau nws lub zog siab. Nws muaj cov ntsiab lus ferrite me ntsis dua li lwm cov qib PH, ua rau nws sib nqus me ntsis. Txhawm rau txhim kho formability, kev kho cua sov tuaj yeem siv ua ntej ua haujlwm txias.
