Ke kila kila TP321 bar/ Paipu kila ʻole / Pepa.
Nā inoa kālepa maʻamau: 321 Stainless, Alloy 321, UNS S32100
ʻO 321 kahi titanium stabilized austenitic chromium-nickel stainless steel i hoʻomohala ʻia e hāʻawi i kahi 18-8 type alloy me ka hoʻomaikaʻi ʻana i ka intergranular-corrosion resistance. nā hiʻohiʻona mau ma nā palena ʻai.Pono e noʻonoʻo ʻia ka 321 no nā noi e koi ana i ka hoʻomehana ʻana ma waena o 8009F (427°C) a me 1650°F (899°C)

321 Nā huahana i loaʻa ma Sekonic Metals
321 kaola & kookoo
Nā lāʻau pōʻai/Paʻa paʻa/Paʻa Hex,Nui Mai 8.0mm-320mm, Hoʻohana ʻia no nā bolts, fastners a me nā ʻāpana ʻokoʻa ʻē aʻe
321 uwea wiliwili & uwea puna
Hoʻolako ʻia ma ka uea kuʻi a me ka uea puna ma ke ʻano coil a ʻoki ʻia ka lōʻihi.
321 pepa & papa
ʻO ka laulā a hiki i 1500mm a me ka lōʻihi a hiki i 6000mm, Mānoanoa mai 0.1mm a 100mm.
321 paipu maʻemaʻe & paipu Welded
Hiki ke hana ʻia ka nui maʻamau a me ka nui i hoʻopili ʻia e mākou me ka hoʻomanawanui liʻiliʻi
321 kāʻei a me ka wili
ʻO ke kūlana palupalu a me ke kūlana paʻakikī me ka ʻili ʻālohilohi AB, ka laulā a hiki i 1000mm
321 Na mea paa
ʻO nā mea kila kila 321 i nā ʻano Bolts, screws, flanges a me nā mea wikiwiki ʻē aʻe, e like me ka kikoʻī o nā mea kūʻai aku.
No ke aha ke kila kila 321?
•Kūleʻa ka oxidation a hiki i 1600°F
•Hoʻopaʻa kūʻē i ka weld wela i hoʻopili ʻia (HAZ) intergranular corrosion
•Kū'ē ka polythionic acid stress corrosion pohā
Steel Alloy 321 kahua noi:
•Nā ʻenekini piston mokulele
•Nā hui hoʻonui
•Ka hana ʻana i nā pū
•Nā mea hoʻoheheʻe wela
•Mea hana hoʻoheheʻe
•Kiʻekiʻe wela kaʻina hana kemika
