Alloy Contents o ka Papa Moly Chrome

ʻO ka papa moly Chrome ma lalo o ka ASTM A387 i nā māka serveral i loaʻa nā ʻokoʻa like ʻole e like me lalo, ʻo Gr 11, 22, 5, 9 a me 91 nā māka hoʻohana maʻamau.

Ma waho aʻe o 21L, 22L a me 91, loaʻa kēlā me kēia papa i ʻelua papa o nā pae ikaika tensile e like me ka wehewehe ʻana i nā papa koi tensile.ʻO ka papa 21L a me 22L wale nō ka Papa 1, a ʻo ka Papa 91 wale nō ka Papa2.

Hoʻomaʻamaʻa wela no A387 Chrom Moly Alloy Steel Plate

E pepehi ʻia ʻo Chrome moly alloy steel plate ma lalo o ASTM A387 i ke kila, me ka thermally mālama ʻia e ka annealing, normarlizing a me ka hoʻoulu ʻana.A i ʻole inā ʻae ʻia e ka mea kūʻai aku, e hoʻomaʻamaʻa wikiwiki ʻia mai ka wela austenitizing ma o ka puhi ʻana i ka ea a i ʻole ka hoʻopau ʻana i ka wai, a ukali ʻia e ka hoʻomaʻamaʻa ʻana, ʻo nā mahana wela haʻahaʻa loa e like me ka papa ma lalo:

Papa	Mahana, °F [°C]
2, 12 a me 11	1150 [620]
22, 22L, 21, 21L a me 9	1250 [675]
5	1300 [705]

E mālama ʻia nā pā kila kila ma ka papa 91 ma o ka hoʻomaʻamaʻa ʻana a me ka hoʻomaʻamaʻa ʻana a i ʻole ka hoʻolili ʻana i ka ea a i ʻole ka hoʻopau ʻana i ka wai, a ukali ʻia e ka hoʻomaʻamaʻa.Pono e hoʻopaʻa ʻia nā papa papa 91 ma 1900 a 1975°F [1040 a 1080°C] a e hoʻomāmā ʻia ma 1350 a 1470°F [730 a 800°C]

ʻO ka papa 5, 9, 21, 21L, 22, 22L, a me 91 mau papa i kauoha ʻia me ka mālama ʻole ʻana i ka wela e ka papa ma luna, e hoʻopau ʻia i loko o ke kūlana hoʻomaha a i hoʻopili ʻia paha.
