309 Mesh Uea Kuhiliʻole

ʻO ke kila kila kila 309 a me 309S he mau kila kila chromium-nickel austenitic i hoʻohana pinepine ʻia no nā noi wela kiʻekiʻe. Ma muli o ko lākou kiʻekiʻe chromium a me ka nickel maʻiʻo, Alloys 309 a me 309S ʻoi loa ka corrosion, ʻoi aku ka nui o ke kūʻē ʻana i ka oxidation, a me ke kūpaʻa wela nani me ka hāʻawi ʻana i nā ʻano maikaʻi ma ka lumi a me nā wela kiʻekiʻe. ʻO ka ʻokoʻa ma waena o Stainless Steel 309 a me 309S ʻo ia ka ʻike kalapona. Loaʻa i ka Alloy 309S kahi hui kalapona liʻiliʻi e hōʻemi i ka ua carbide a hoʻomaikaʻi i ka weldability. Nā hiʻohiʻona

• ʻO ka wela kiʻekiʻe o 1000 ° C i ka lawelawe ma ka lewa
• Kūʻē maikaʻi loa i ka carburizing
• Maikaʻi weldability a me ka formability
• Kūʻē maikaʻi i ka corrosion a me ka oxidation

Nā noi

• Nā mea hoʻomehana
• Nā ʻāpana mokulele a me nā ʻenekini jet
• Nā mea hoʻololi wela
• Carburizing annealing huahana
• ʻO nā mea hana waiʻona Sulphite
• Kiln liners
• Pahu paila
• ʻO nā mea hana hoʻoheheʻe a me nā mea hana kemika
• ʻāpana hoʻopau kaʻa

FAQ
Q: Pehea ka lōʻihi o kāu manawa hoʻouna?
A: ʻO ka maʻamau he 5-10 mau lā inā loaʻa nā waiwai. a i ʻole he 15-20 mau lā inā ʻaʻole i loaʻa nā waiwai, e like me ka nui.
Q: Hāʻawi anei ʻoe i nā laʻana? He manuahi a keu paha ?
A: ʻAe, hiki iā mākou ke hāʻawi i ka hāpana no ka uku manuahi akā ʻaʻole e uku i ke kumukūʻai o ka ukana.
Q: He aha kāu mau ʻōlelo uku?
A: Uku <= 1000USD, 100% ma mua. Uku> = 1000USD, 30% T /T ma mua, kaulike ma mua o ka hoʻouna ʻana.
