17-4PH 630 1.4542 H900 faraantiga been abuurka ah sida ku xusan sawirada
1)AMS 5643
Da'da heerkulka hooseeya ee adkeynaya kuleylka si loo soo saaro sifooyin farsamo oo heer sare ah
heerarka xoogga.
2) shuruud:
Waxaa lagu siin karaa xaalad la jeexjeexay (Xaaladda A), ama kulaylka loola dhaqmo sida soo socota:-
Xaaladda H900 (900°F) Xaaladda H925 (925°F) Xaaladda H1025 (1025°F) Xaaladda H1075 (1075°F)
H1100 (1100°F) Xaaladda H1150 (1150°F)
Walaxda AMS 5643 (17/4 PH) waa in aan loo isticmaalin xaalada la tirtiray. Darajadan birta aan la taaban karin waxay leedahay mid caadi ah
cufnaanta 7.75kg/dm3 waana magnetizable.

4. Sawirada wax soo saarka:
5. AMS 5643 Iska caabinta Daxalka:
AMS 5643 (17/4 PH) wuu ka sarreeyaa darajooyinka chrome-ka tooska ah sida 410 wuxuuna u dhawaadaa caabbinta daxalka ee nikkel
darajooyinka chrome. Warbaahino badan oo daxalka leh, waxay la mid tahay fasalka 302. Iska caabbinta daxalka waxay saameyn doontaa dhamaystirka dusha sare iyo
daaweynta kulaylka gabowga. AMS 5643 (17/4 PH) si fiican bay alxanaysaa waxaana lagu alxan karaa dhammaan hababka ganacsiga. Kuleylinta ka hor iyo
hababka kulaylka dambe ee darajooyinka birta adag ee caadiga ah looma baahna.
6. Codsiga AMS 5643:
Codsiyada u baahan xoog sare iyo iska caabin daxalka wanaagsan, iyo sidoo kale xoogga daalka sare, caabbinta xirashada wanaagsan
iyo iska caabin daxalka stress. Waxay ku habboon tahay qaybaha adag ee u baahan mashiinnada iyo alxanka, waxayna u baahan yihiin xorriyadda qallafsanaan.
Loo isticmaalo hawada sare, difaaca saliidda xeebaha iyo warshadaha gaaska. Waxaa loo isticmaalaa qaybo makaanik ah sida qaybaha hagaha, ulaha mootada, afkoda waalka,
gear, iwm.
