Dab tsi yog 17-7 pkipitation hardening stainless hlau?

AISI 631 Cov hlau Stainless, tseem hu ua 17 - 7 p p, yog ib qho nag lossis daus ua rau lub stainless hlau, yog nag xob nag cua tawv. Nws muaj 15-17% cr, 6. {{5% Nws muaj zog siv hauv kev ua kom sov, thiab lwm yam.

17-7 pha pawj stainless hlau txias-rolled cov cai ntawm acid, xws li theem kawg txav tuaj txog ntawm cov chav turch. Nws yog qhov tsim nyog rau cov txheej txheem qhov chaw nrog ua haujlwm kub hauv qab no 300 degree hauv kev xeb ib puag ncig.
