Kev Taw Qhia Txog 17-4ph Stainless Steel

17-4 stainless hlau phaj (630) yog cov khoom siv stainless hlau chromium-tooj ​​liab uas siv rau cov ntawv thov uas xav tau lub zog siab thiab qib nruab nrab ntawm kev tiv thaiv corrosion. Lub zog siab yog
tswj tau txog li 600 degrees Fahrenheit (316 degrees)
Celsius).

Cov Khoom Siv Dav Dav

Cov hlau tsis xeb Alloy 17-4 PH yog cov hlau tsis xeb martensitic uas muaj zog nrog Cu thiab Nb / Cb ntxiv. Cov qib no ua ke muaj zog, tawv (txog li 572 ° F / 300 ° C), thiab xeb.
kev tiv thaiv.

Kev Tiv Thaiv Kev Xeb

Cov hlau nplaum 17-4 PH tiv taus kev tawm tsam corrosive zoo dua li cov hlau stainless hlau uas ruaj khov thiab sib piv tau rau Alloy 304 hauv feem ntau cov xov xwm.

Yog tias muaj kev pheej hmoo ntawm kev tawg ntawm kev ntxhov siab, qhov kub siab dua yuav tsum tau xaiv tshaj 1022 ° F (550 ° C), zoo dua 1094 ° F (590 ° C). 1022 ° F (550 ° C) yog qhov kub zoo tshaj plaws hauv chloride media.

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

Cov hlau no yuav raug kev tawg lossis kev tawm tsam yog tias raug dej hiav txwv tsis tu ncua rau ib lub sijhawm ntev npaum li cas.

Nws tiv taus xeb hauv qee yam tshuaj lom neeg, roj av, ntawv, mis nyuj thiab kev lag luam ua zaub mov (sib npaug rau qib 304L).
