ʻO ka hale kūʻai kūʻai kila kila kila - 17-4PH 630 1.4542 H900 hoʻopaʻa apo e like me nā kiʻi - Huaxin Detail:
1) ʻO AMS 5643 (17/4 PH) he kila kila kila aerospace ʻAmelika me 4% keleawe hiki ke paʻakikī.
e ka haʻahaʻa haʻahaʻa haʻahaʻa precipitation paʻakikī ka wela wela e hana maikaʻi loa mechanical waiwai ma kiʻekiʻe
pae ikaika.
2) kūlana:
Hiki ke hoʻolako ʻia ma ke kūlana annealed (Condition A), a i ʻole mālama ʻia ka wela e like me kēia: -
Kūlana H900 (900°F) Kūlana H925 (925°F) Kūlana H1025 (1025°F) Kūlana H1075 (1075°F) Kūlana
H1100 (1100°F) Kūlana H1150 (1150°F)
ʻAʻole pono e hoʻohana ʻia nā mea AMS 5643 (17/4 PH) ma ke kūlana annealed. He ʻano maʻamau kēia papa o ke kila kila
7.75kg/dm3 a hiki ke hoʻopaneʻe.

ʻOi aku ka maikaʻi o AMS 5643 (17/4 PH) ma mua o nā māka chrome pololei e like me 410 a hoʻokokoke i ka pale ʻana o ka nickel.
nā māka chrome. I loko o ka nui o nā media corrosive, ua like ia me ka papa 302. E hoʻopilikia ʻia ke kūʻē ʻana i ka corrosion e ka pau ʻana o ka ʻili a
lapaau wela kahiko. AMS 5643 (17/4 PH) welds maikaʻi loa a hiki ke welded e nā kaʻina hana pāʻoihana a pau. Hoʻomaʻamaʻa mua a
ʻAʻole koi ʻia nā hana hoʻomaʻamaʻa postheating maʻamau maʻamau hardenable stainless steel grades.
6. Noi AMS 5643 :
No nā noi e koi ana i ka ikaika kiʻekiʻe a me ke kūpaʻa corrosion maikaʻi, a me ka ikaika luhi kiʻekiʻe, ke kūpaʻa maikaʻi
a me ke koʻikoʻi kūʻē i ka corrosion. He kūpono ia no nā ʻāpana paʻakikī e koi ana i ka mīkini a me ka welding, a koi i ke kūʻokoʻa o ka deformation.
Hoʻohana ʻia i loko o ka aerospace, pale ʻaila aila a me ʻoihana kinoea. Hoʻohana ʻia ia no nā ʻāpana mechanical e like me nā ʻāpana alakaʻi, nā ʻāpana kaʻa, nā ʻōpala valve,
nā mīkini, etc.
