AISI 4140 Alloy Steel

AISI 4140 Alloy Steel (UNS G41400)

Ua koho ʻia nā kila huila e ka AISI mau helu ʻehā a loaʻa nā ʻano kila like ʻole, kēlā me kēia me ka haku mele i ʻoi aku ma mua o nā palena o B, C, Mn, Mo, Ni, Si, Cr, a me Va i hoʻonohonoho ʻia no nā kila kalapona.

ʻO ke kila kila AISI 4140 he chromium-, molybdenum-, a me ka manganese me ke kila kila haʻahaʻa. Loaʻa iā ia ka ikaika luhi kiʻekiʻe, ka abrasion a me ke kūpaʻa hopena, ka paʻakikī, a me ka ikaika torsional. Hāʻawi ka ʻikepili ma lalo nei i kahi hiʻohiʻona o ke kila kila AISI 4140.

AISI 4140 kila kila i maikai machinability i ka annealed kulana.

Hoʻokumu

AISI 4140 kila kila he kiʻekiʻe ductility. Hiki ke hana ʻia me ka hoʻohana ʻana i nā ʻenehana maʻamau i ke kūlana annealed. Pono ia i ke kaomi a i ʻole ka ikaika no ka hana ʻana no ka mea ʻoi aku ka paʻakikī ma mua o nā kila kalapona maʻamau.

wiliwili

Hiki ke wili ʻia ke kila kila AISI 4140 me ka hoʻohana ʻana i nā ʻenehana maʻamau. Eia nō naʻe, e hoʻopili ʻia nā ʻano mechanical o kēia kila ke hoʻopili ʻia i ke kūlana wela, a pono e hana ʻia ka hana wela ma hope o ka weld.

Hoʻomaʻamaʻa Wela

Hoʻomaʻamaʻa ʻia ke kila kila AISI 4140 ma 845 ° C (1550 ° F) a ukali ʻia e ke kinai ʻana i ka ʻaila. Ma mua o ka paʻakikī, hiki ke hoʻomaʻamaʻa ʻia ma ka hoʻomehana ʻana ma 913°C (1675°F) no ka manawa lōʻihi, a ukali ʻia e ka hoʻoluʻu ea.

Ke kalaiwa ana

Hana ʻia ke kila kila AISI 4140 ma 926 a 1205°C (1700 a 2200°F)

Hana Wela

AISI 4140 hiki ke hana wela ma 816 a 1038°C (1500 a 1900°F)

Hana anu

Hiki ke hoʻohana ʻia ke kila kila AISI 4140 me ka hoʻohana ʻana i nā ʻano hana maʻamau i ke kūlana annealed.

Hoʻopili

Hoʻopili ʻia ke kila kila AISI 4140 ma 872°C (1600°F) a ukali ʻia e ka hoʻolili mālie ʻana i ka umu.

ʻO ka hoʻohenehene

AISI 4140 hiki ke hoʻoluliluli ʻia ke kila kila ma 205 a 649°C (400 a 1200°F) ma muli o ka pae paʻakikī i makemake ʻia. Hiki ke hoʻonui i ka paʻakikī o ke kila inā he haʻahaʻa haʻahaʻa haʻahaʻa. No ka laʻana, hiki ke loaʻa ka ikaika tensile o 225 ksi ma o ka hoʻoulu ʻana ma 316°C (600°F), a hiki ke loaʻa i ka ikaika tensile o 130 ksi ma ka hoʻoulu ʻana ma 538°C (1000°F).

Paʻakiki

Hiki ke hoʻopaʻakikī ʻia ke kila kila AISI 4140 e ka hana anu, a i ʻole ka hoʻomehana ʻana a me ke kinai ʻana.
