Taw qhia Ntawm 17-4ph Stainless Hlau

17-4 stainless hlau phaj (630) yog chromium-tooj ​​liab nag lossis daus hardening stainless hlau cov ntaub ntawv siv rau kev siv uas yuav tsum tau muaj zog thiab ib nrab ntawm corrosion kuj. Siab zog yog
khaws cia kom txog li 600 degrees Fahrenheit (316 degrees
Celsius).

General Properties

Stainless hlau Alloy 17-4 PH yog nag lossis daus hardening martensitic stainless hlau nrog Cu thiab Nb / Cb ntxiv. Cov qib sib xyaw ua ke siab zog, hardness (txog 572 ° F / 300 ° C), thiab corrosion
tsis kam.

Corrosion Resistance

Alloy 17-4 PH tiv thaiv corrosive tawm tsam zoo dua li ib qho ntawm cov txheej txheem hardenable stainless hlau thiab yog piv rau Alloy 304 hauv feem ntau tshaj tawm.

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

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

Lub alloy yog raug rau crevice los yog pitting nres yog raug rau cov dej hiav txwv stagnation rau txhua lub sij hawm.

Nws yog corrosion resistant nyob rau hauv ib co tshuaj, roj av, ntawv, mis nyuj thiab zaub mov ua lag luam (sib npaug rau 304L qib).
