17-7PH yog austenitic-martensitic nag lossis daus hardening stainless hlau tsim nyob rau hauv lub hauv paus ntawm 18-8CrNi, tseem hu ua tswj theem hloov stainless hlau.Thaum cov tshuaj kho kub, 1900 ° F, cov hlau yog austenitic tab sis undergoes transformation mus rau ib tug tsawg- carbon martensitic qauv thaum lub sij hawm txias rau chav tsev kub.Qhov kev hloov pauv no tsis ua tiav kom txog thaum qhov kub poob mus rau 90 ° F.Tom qab cua sov rau qhov kub ntawm 900-1150 ° F rau ib mus rau plaub teev nag lossis daus ntxiv dag zog rau cov hlau.Qhov kev kho hardening no kuj tempers cov qauv martensitic, nce ductility thiab toughness
