Nā ʻIke Alloy o ka Chrome Moly Plate

ʻO ka papa Chrome moly ma lalo o ASTM A387 ma nā ʻano like ʻole me nā ʻano metala like ʻole e like me lalo nei, nā ʻano hoʻohana maʻamau ʻo Gr 11, 22, 5, 9 a me 91.

Koe wale nō ʻo 21L, 22L a me 91, loaʻa kēlā me kēia papa i ʻelua mau papa o nā pae ikaika tensile e like me ka mea i wehewehe ʻia ma nā papa koi tensile. Loaʻa i nā papa 21L a me 22L ka Papa 1 wale nō, a ʻo ka Papa 91 ka Papa 2 wale nō.

Ka Lapaʻau Wela no ka Papa Kila Chrom Moly Alloy A387

ʻO ka papa kila Chrome moly ma lalo o ASTM A387 e pepehi ʻia i ke kila, me ka mālama wela ʻia ma o ka annealing, normallizing a me ka tempering. A i ʻole inā ʻae ʻia e ka mea kūʻai, hoʻolalelale ʻia ka hoʻomaʻalili ʻana mai ka mahana austenitizing ma o ka pahū ʻana o ka ea a i ʻole ka hoʻopau ʻana i ka wai, a ukali ʻia e ka tempering, ʻo ka liʻiliʻi o ka mahana tempering e like me ka papa ma lalo nei:

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

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

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