E hoʻokaʻawaleʻo Alloy A320 l7 l7m i kaʻenehana kūikawā kūikawā no ka hana haʻahaʻa haʻahaʻa
ʻO kaʻikepili o ka carbon o 4140 he 0.15-0.25% kiʻekiʻe loa ma kānaʻano. Hiki i ke kumu ke wela i ka leʻaleʻa a me ka hana maʻamau i ka lewa, a iʻole ka nui a me ka quench a me ka huhū ma polymer a iʻole aila.
Ke'ōlelo ikaika nei, he mea kūʻai nā mea āpau a pau, akāʻaʻole nā mea a nā kila āpau i kapaʻiaʻo "nā kāhila alloy". ʻO nā kila maʻalahi i ka hao (fe) a me nā carbon (c) kapaʻia kēia i kapaʻia nā cheels carbon. Eia nō naʻe,ʻo ka hua'ōlelo "Alloy Steel"ʻo ia ka'ōlelo maʻamau e pili ana i nā mea pāʻani me nā mea'ē aʻe e hoʻohui i nā mea'ē aʻe i hoʻohuiʻia i ka carbon. Hoʻopili nā mea maʻamau maʻamau ma ka manganese (ʻo ia ka mea maʻamau), nickel, moldium, moldium,ʻo ka mildi a me Boron. E kiʻi i nā analretamlelo maʻamau,ʻo'Eluminum,ʻo Coreld, keleawe,ʻo Timium, TIN, Zikc, Na Zircotium.
Astm nā mea kiko'ī e hāʻawi i kahi waiwai haʻahaʻa haʻahaʻa haʻahaʻa loa no ka Astm A ADM ATMS A ATTM A320 L7 Stud Bolts A 20-FT-LBF @ -150F. E hoʻoholo ka hōʻikeʻana o ka hōʻikeʻana i ka nui o ka ikehu i ka nui o ka ikehu i nā mea i hanaʻia e kahi mea i hoʻopaʻaʻia e ke kumu kūʻai.
