Intangiriro Ya 17-4ph Ibyuma

17-4 isahani idafite ibyuma (630) ni imvura ya chromium-umuringa ikomera ibikoresho byuma bidafite ibyuma bikoreshwa mubisabwa bisaba imbaraga nyinshi kandi biringaniye birwanya ruswa.Imbaraga nyinshi ni
yagumishijwe kuri dogere 600 Fahrenheit (dogere 316
Celsius).

Ibintu rusange

Ibyuma bitagira umuyonga Alloy 17-4 PH ni imvura ikomera martensitike ibyuma bitagira ibyuma hamwe na Cu na Nb / Cb wongeyeho.Urwego rukomatanya imbaraga nyinshi, gukomera (kugeza kuri 572 ° F / 300 ° C), no kwangirika
kurwanywa.

Kurwanya ruswa

Alloy 17-4 PH ihanganira ibitero byangirika neza kuruta icyuma gisanzwe gishobora gukomera kandi ntigereranywa na Alloy 304 mubitangazamakuru byinshi.

Niba hari ingaruka zishobora guterwa no kwangirika, ubushyuhe bwo hejuru busaza noneho bugomba gutoranywa hejuru ya 1022 ° F (550 ° C), byaba byiza 1094 ° F (590 ° C).1022 ° F (550 ° C) nubushyuhe bwiza bwogukoresha mubitangazamakuru bya chloride.

1094 ° F (590 ° C) nubushyuhe bwiza bwubushyuhe mubitangazamakuru bya H2S.

Amavuta ashobora kwibasirwa cyangwa kwibasirwa iyo ahuye n’amazi yo mu nyanja adahagaze umwanya muremure.

Irwanya ruswa mu nganda zimwe na zimwe z’imiti, peteroli, impapuro, amata n’inganda zitunganya ibiribwa (bihwanye n’icyiciro cya 304L).
