Qhia txog 17-4k stainless hlau

17-4 Cov roj qis dua (630) yog 630) yog cov chromium-tooj ​​liab cov khoom siv rau cov ntawv thov kom muaj zog thiab qib siab ntawm corrosion tsis kam. Lub zog siab yog
tswj kom kwv yees li 600 degrees Fahrenheit (316 degrees
Celsius).

Corrosion Kuj

Alloy 17-4 pH withstands corrosive kev tawm tsam zoo dua li ib qho ntawm cov qauv nyuaj ntawm cov hlau uas tsis muaj zog thiab muaj piv rau Alloy 304 hauv feem ntau cov xov xwm.

Yog tias muaj cov peev xwm txaus ntshai ntawm kev ntxhov siab corrosion, qhov siab dua kev kub siab ces yuav tsum tau xaiv tshaj li 1022 ° F (594 ° F (590 ° C). 1022 ° F (550 ° C) yog qhov zoo tshaj plaws tempering hauv chloride media.

1094 ° F (590 ° C) yog qhov zoo tshaj plaws tempering kub hauv H2S media.

Lub alloy yog yuav tsum tau crevice lossis pitting nres yog tias raug rau cov dej hiav txwv stagntater rau ib lub sijhawm twg.

Nws yog corrosion resistant hauv qee cov tshuaj lom neeg, roj av, ntawv, mis los thiab kev ua khoom noj khoom haus (sib npaug rau 304L qib).
