ʻO ka pākuhiʻo Aloy Steel Poki
Astm A333ʻO kahi kiko'ī maʻamau no nā carbonʻole a me nā kila kila a me nā koho balota e koi ai i ka haʻahaʻa haʻahaʻa. ʻO ka uhiʻana i kēia mau papa inoa o nā mea kanu ferritic: ka papa o ka papa he 4, ka papa he 10, ka nui o ka papaʻaina. Pono nā pipes e hoʻokaʻawale i nā hoʻoponoponoʻana i nā mea hoʻoponopono, a iʻole ma o ka radiographic a me ka ho'āʻoʻana i ka ultrasonic.
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.
ʻO B7 a me B7M e wela e wela e ka quenching i loko o ka wai wai a me ka huhū. No nā mea e nui ai B7m i ka mālamaʻana i ka wela wela,ʻo ia ka hanaʻana o ka hana inā mālamaʻia ma hope o nā hana āpau, a me nāʻano helu kuʻina.
