AISI 4140 Steel 1.7225 42CrMo4 SCM440

AISI 4140 Alloy Steel inowanikwa chromium-molybdenum simbi inowanzo shandiswa mushure mekudzimwa uye kudzimwa, ine kusimba kwepamusoro, kuomarara kwepamusoro. Iyo alloy 4140 ndiro zvakare ine yakanyanya kuneta simba uye yakanaka yakaderera-tembiricha kukanganisa kuoma.

Gnee ine mukana mukuru pa4140 simbi ndiro:

• 1500+ matani zuva nezuva e4140 alloy plate kana flat bar.
• Hot rolled / annealed / Q+T (PH prehardened) mamiriro aripo.
• Ukobvu 4-300mm unowanikwa kwemazuva 1-3 kutumira.
• Ukobvu 1-10mm inotonhora yakakungurutswa pepa kwemazuva makumi matatu ekutungamira nguva.
• Cheka kuhupamhi & kucheka kusvika kureba sevhisi iripo.
• Yakagadzirwa kushivirira & roughness zvidimbu sevhisi iripo.

Pakukurukura nezveAISI 4140, zvakakosha kuti unzwisise zvinorehwa nenhamba yegiredhi:

AISI 4140 inogadzirwa nekuisa simbi, kabhoni, uye zvimwe zvinosanganiswa zvinhu muchoto chemagetsi kana muchoto weokisijeni. Iwo makuru alloying zvinhu akawedzerwa kuAISI 4140 ndeaya:

• Chromium
• Manganese
• Molybdenum

Kamwe simbi, kabhoni, uye zvimwe zvinosanganiswa zvinhu zvakasanganiswa pamwechete muchimiro chemvura, zvinotenderwa kutonhora. Simbi yacho inogona kubva yanyudzwa; zvichida kakawanda.

Mushure mekunge kunyungudutswa kwapera, simbi inodziyiswa kusvika pachikamu chakanyungudutswa zvakare kuitira kuti igone kudururwa muchimiro chaunoda uye inogona kunge ichipisa yakashandwa kana kutonhora inoshandiswa kuburikidza nema roller kana mamwe maturusi kuti asvike ukobvu hunodiwa. Ehezve, kune mamwe maoperation akakosha anogona kuwedzerwa kune izvi kuderedza mill scale kana kunatsiridza ma mechanic properties.

AISI 4140 isimbi yakaderera alloy. Yakaderera alloy simbi inotsamira pane zvimwe zvinhu kunze kwesimbi uye kabhoni kuti iwedzere iwo mechanic zvimiro. MuAISI 4140, mawedzero echromium, molybdenum, uye manganese anoshandiswa kuwedzera kusimba uye kuoma kwesimbi. Kuwedzerwa kwechromium uye molybdenum ndicho chikonzero nei AISI 4140 ichionekwa se "chromoly" simbi.

Kune akati wandei akakosha emuchina zvivakwa zveAISI 4140, kusanganisira:

• Tensile Strength: AISI 4140 simbi kazhinji ine chinangwa chekupedzisira simba rekusimba rinosvika 95,000 psi.
• Kuoma
• Ductility
• Kuoma

Tafura iri pazasi inoratidza kuumbwa kwemakemikari eAISI 4140:

Kuwedzerwa kwechromium uye molybdenum kunosimudzira kusagadzikana kwekuora. Iyo molybdenum inogona kunyanya kubatsira kana ichiedza kuramba ngura nekuda kwekloridhi. Iyo manganese muAISI 4140 inoshandiswa kuwedzera kuoma uye se deoxidizer. Mune alloy simbi, manganese inogona zvakare kusangana nesarufa kuvandudza machinability uye kuita kuti carburizing process ishande.
