Alloy 347H mea he stabilized, austenitic, chromium kila i loko o ka columbium e hiki ai no ka hoopau ana i ka carbide precipitation, a no laila, intergranualr corrosion.Hoʻopaʻa ʻia ʻo Alloy 347 e ka hoʻohui ʻana o ka chromium a me ka tantalum a hāʻawi i nā waiwai ʻoi aku ka nui o ka creep a me ke koʻikoʻi ma mua o ka alloy 304 a me 304L hiki ke hoʻohana ʻia no nā hōʻike kahi e hopohopo ai ka sensitization a me intergranualr corrosion.ʻO ka hoʻohui ʻana o ka columbium e hiki ai i ka Alloy 347 ke loaʻa i ke kūpaʻa corrosion maikaʻi loa, ʻoi aku ka maikaʻi ma mua o ka alloy 321. ʻO 347H ka ʻano hui kalapona kiʻekiʻe o Alloy 347 a hōʻike i ka hoʻomaikaʻi ʻana i ka wela kiʻekiʻe a me nā waiwai kolo.Aia ka Haosteel Stainless inventory i kēia manawa me Alloy 347/347H (UNS S34700/S34709) i loko o ka pepa, ka ʻili pepa, ka pā, ka pā poepoe, ka pā pālahalaha i hana ʻia a me nā huahana tubular.

Nā noi

Hoʻohana pinepine ʻia ʻo Alloy 347H no ka hana ʻana i nā mea hana, pono e kau ʻia i ka lawelawe ma lalo o nā kūlana corrosive koʻikoʻi, a he mea maʻamau hoʻi i nā ʻoihana hoʻomaʻemaʻe ʻaila.

 

Paʻa ʻino:

.Hāʻawi like i ke kūpaʻa ʻana i ka maʻamau, ka corrosion holoʻokoʻa e like me Alloy 304

.Hoʻohana ʻia no nā noi i hiki ke hoʻopili ʻia nā alloys e like me Alloy 304 i ka intergranualr corrosion.

.Hoʻohana maʻamau no nā lako welded kaumaha ʻaʻole hiki ke hoʻopili ʻia a no nā mea hana

 

hana ʻia ma waena o 800 a 150°F (427 a hiki i 816°C)

.ʻOi aku ka Alloy 347 ma mua o Alloy 321 no ka wai a me nā wahi wela haʻahaʻa

.Hoʻohana mua ʻia i nā wahi wela kiʻekiʻe kahi e pono ai ke kūʻē ʻana i ka sensitization, a laila e pale i ka corrosion intergranualr ma nā pae haʻahaʻa.

.Hiki i ke koʻikoʻi i ka haki ʻana i ka corrosion

.Hōʻike i ka pale ʻana i ka oxidation e like me nā 18-8 austenitic stainless steel ʻē aʻe
