Kuyambitsa kwa 17-4ph Stainless Steel

17-4 chitsulo chosapanga dzimbiri (630) ndi chromium-mkuwa mpweya woumitsa zitsulo zosapanga dzimbiri zomwe zimagwiritsidwa ntchito pazinthu zomwe zimafuna mphamvu zambiri komanso kukana kwa dzimbiri. Mphamvu zazikulu ndi
imasungidwa mpaka pafupifupi madigiri 600 Fahrenheit (madigiri 316
Celsius).

General Properties

Chitsulo chosapanga dzimbiri Aloyi 17-4 PH ndi mpweya woumitsa chitsulo chosapanga dzimbiri cha martensitic chokhala ndi zowonjezera za Cu ndi Nb/Cb. Gululi limaphatikiza mphamvu zambiri, kuuma (mpaka 572 ° F / 300 ° C), ndi dzimbiri.

Kukaniza kwa Corrosion

Aloyi 17-4 PH imapirira zowononga bwino kuposa zitsulo zilizonse zosapanga dzimbiri zolimba ndipo zimafanana ndi Alloy 304 pama media ambiri.

Ngati pali chiopsezo cha kupsinjika kwa dzimbiri kusweka, kutentha kwapamwamba kukalamba ndiye kuyenera kusankhidwa pa 1022 ° F (550 ° C), makamaka 1094 ° F (590 ° C). 1022 ° F (550 ° C) ndiye kutentha koyenera kwambiri muzofalitsa za chloride.

1094 ° F (590 ° C) ndiye kutentha koyenera kwambiri mu H2S media.

Aloyiyo imatha kuphwanyidwa kapena kuphulika ngati ili ndi madzi a m'nyanja osasunthika kwa nthawi yayitali.

Imalimbana ndi dzimbiri m'mafakitale ena amankhwala, mafuta, mapepala, mkaka ndi zakudya (zofanana ndi kalasi ya 304L).
