17-4PH 630 1.4542 H900 ring ring ngokwemizobo
1) I-AMS 5643 (17/4 PH) yintsimbi ye-aerospace yaseMelika ene-4% yobhedu enokuqina.
ngemvula yobushushu obuphantsi iqinisa unyango lobushushu ukuvelisa iimpawu ezibalaseleyo zoomatshini phezulu
amanqanaba amandla.
2) imeko:
Inokubonelelwa kwimeko ye-annealed (uMqathango A), okanye ubushushu buphathwe ngolu hlobo lulandelayo:-
Imeko H900 (900°F) iMeko H925 (925°F) iMeko H1025 (1025°F) iMeko H1075 (1075°F)
I-H1100 (1100°F) imeko H1150 (1150°F)
I-AMS 5643 (17/4 PH) imathiriyeli ayifanele isetyenziswe kwimeko yokufakwa. Eli bakala lensimbi engenasici linesiqhelo
Uxinaniso lwe-7.75kg/dm3 kwaye luyakwazi ukusebenza ngemagnethi.

4. Imifanekiso yemveliso:
5. AMS 5643 Ukumelana nokuTyakala:
I-AMS 5643 (17/4 PH) yongamile kunamabakala e-chrome athe ngqo afana ne-410 kwaye isondela kwi-corrosion resistance ye-nickel.
amabanga e-chrome. Kwimithombo yeendaba ezininzi ezitshabalalisayo, ilingana neklasi 302. Ukuxhatshazwa kwe-Corrosion kuya kuchaphazeleka ngokugqitywa kwendawo kunye
ukuguga unyango lobushushu. I-AMS 5643 (17/4 PH) idibanisa kakuhle kakhulu kwaye inokudityaniswa zizo zonke iinkqubo zorhwebo. Ukufudumala kunye
iinkqubo zokufudumeza zamabanga asemgangathweni wentsimbi engenastainless ayimfuneko.
6. AMS 5643 Isicelo :
Kwizicelo ezifuna ukomelela okuphezulu kunye nokuchasana okuhle kokubola, kunye namandla aphezulu okudinwa, ukumelana nokunxiba kakuhle.
kunye noxinzelelo lwe-corrosion resistance. Ifanelekile kwiindawo ezinzima ezifuna i-machining kunye ne-welding, kwaye zifuna inkululeko yokuguqulwa.
Isetyenziswa kwi-aerospace, ukukhusela ioli ekude nonxweme kunye nemizi-mveliso yerhasi. Isetyenziselwa amacandelo oomatshini anjengendawo yesikhokelo, i-motor shafts, iziqu zevalve,
iigiya, njl.
