Aisise 4140 alloy chitsulo ndi chromium Molbdenum shalsication zitsulo zomwe zimagwiritsidwa ntchito mwawiri zigawo zikuluzikulu zamitundu yambiri, monga ma shars, magiya ndi mapulani ena.
Mipiringidzo yachitsulo:
Aisi 4140, 1.7225 (42crmon (42crmo4), scm440, ndi B7 zitsulo ndizosiyana ndi zitsulo zofanana ndi chitsulo chomwechi. Amadziwika kuti ndi mphamvu zambiri komanso mphamvu, yomwe nthawi zambiri imagwiritsidwa ntchito pogwiritsa ntchito ngati magiya ndi ma balts. Aisi 4140 ndi dzina la America, 1.7225 ndi muyezo waku Europe, ScM440 ndi dzina la Jais Japan, ndipo B7 amatchula msonkhano wa Asm ASM ASM ASME A ASMNA. Masankho awa amaimira chromium-molybdenum alloy chitsulo chofanana ndi zinthu zofanana, ndipo kusankha kumadaliranso miyezo yachigawo kapena yamakampani.

Mawonekedwe & Ubwino:
•Mphamvu yayikulu: Mabala achitsulo awa akuwonetsa mphamvu zapamwamba, ndikuwapangitsa kukhala oyenera ntchito komwe mphamvu ndi kulimba ndizovuta.
•Kulimba: Amapereka kulimba mtima kwabwino komanso kupewa kukhuza, kumawapangitsa kuti akhale ndi katundu wolemera komanso zipsinjo zazikulu.
•Kusiyanitsa: Aisi 4140, 1.7225, 42crto4, scmrMo4, scm440, ndi b7, ndi magiya, magiresi, ndi zigawo zikuluzikulu.
•Kuthekera Kukaniza: Zinthu zokopa, monga chromium ndi molybdenum, zimathandizira kuti zitheke kukana, kupanga miyala yachitsulo yoyenera kugwiritsa ntchito mikhalidwe.
•Makina: Zipewa izi zimakhala ndi makina abwino akamachita bwino, othandizira kugwiritsa ntchito njira zopangira makina nthawi yomwe nsalu.
•Kudya: kumatha kuwunikidwa, ngakhale kuti kuphatikiza ndi kutumiza kwa kutentha ndi kutumiza kwa kutentha kungafunike kukhalabe ndi zinthu zomwe mukufuna ndikupewa nkhani monga kusokonekera monga kusokonezeka.

Chitsogozo cha Faq:
Chifukwa chiyani tisankhe?
•Mutha kupeza zinthu zabwino malinga ndi zomwe mukufuna pamtengo wochepera.
•Timaperekanso obwezeretsanso, fob, CFR, COB, ndi khomo ndi mitengo ya khomo. Tikukulimbikitsani kuti muchite zotumizira zomwe zingakhale zachuma.
•Zipangizo zomwe timapereka ndizotsimikizika kwathunthu, kuchokera ku satifiketi ya sifiketi yomaliza yomaliza. (Malipoti adzawonetsa zofunikira)
•Tikutsimikizira kuyankha mkati mwa 24hours (nthawi zambiri nthawi yomweyo)
•Perekani lipoti la SGS.
•Timadzipereka kwambiri kwa makasitomala athu. Ngati sizingatheke kukwaniritsa zofunikira zanu mutapenda zosankha zonse, sitikusocheretsani popanga malonjezo abodza omwe angapangitse ubale wabwino womwe ungapangitse ubale wabwino.
•Perekani ntchito imodzi.
4140 vs 42crmo4 - kusiyana ndi chiyani?
Aisi 4140 ndi 42cmonlo4 ndi mtundu womwewo wa chitsulo, ndi Aisi 4140 kukhala waku America ndi 42cmon woyenera ku European. Amagawana nyimbo zofananira, mphamvu zambiri, komanso kulimba, zimawapangitsa kukhala oyenera pakugwiritsa ntchito ngati magiya ndi ma balts. Ngakhale mumatchulapo mayina osiyanasiyana komanso mfundo zachigawo, nthawi zambiri amadziwika kuti ndi ofananira.
Kodi 42cmon ndi chiyani?
42cmo4 ndi chromium-molybdenum alloy steel osankhidwa ndi mphamvu yaku Europen 10083. Amadziwika chifukwa champhamvu kwambiri, kulimba, komanso kuuma. Ndi zokhudzana ndi 0,38% mpaka 0.45%, nthawi zambiri imagwiritsidwa ntchito pofunsira zinthu zokhazikika, monga magiresi, ma grankshafts, ndi ndodo zolumikizira mafakitale ndi astospace. Chitsulo chimayankha bwino mankhwalawa, ndikupangitsa kuti zinthu zizitha kugwiritsa ntchito makina, ndipo zimawerengedwa ngati zofanana ndi zinthu zina ngati Aisi 4140 ndi ScM440.
Kodi nambala ya kalasi ya B7 ndi chiyani?
Gawo B7 ndi lingaliro mkati mwa Astm A193 Standard, yomwe imaphimba zida zapamwamba kuti mugwiritse ntchito kutentha kwambiri kapena ntchito yayikulu. ASTM A193 ndiogwiritsa ntchito ku Astm Internatiyi (yomwe yomwe idali yodziwika kuti American Society yoyesa ndi zida) ndipo imagwiritsidwa ntchito kwambiri mu mafuta a chromium. Izi zimazimitsidwa ndi kukwiya (kukwiya) kuti mukwaniritse zomwe mukufuna. When specified, materials must meet the requirements outlined in the ASTM A193 and A194 standards to ensure proper strength, ductility, and other mechanical properties.
