SAE4340 Steel Round Bar ASTM4340 Steel Rod
Features
Izvo zvinhu zve 4340 simbi bhaa ndeye alloy structural simbi.Yakaenzana neGerman DIN simbi giredhi 36CrNiMo4 , French NF standard 40NCD3, Japanese JIS standard SNCM439, British BS standard 816M40, American SAE/ASTM4340, American UNS standard G43400，China Standard 40CrNiMoA.
SAE4340 inozivikanwa se alloy structural simbi kana composite simbi.Simbi ine nickel iri pakati pe1.65 ne2.00, ine simba rakawanda, kusimba, kugona kuomarara, uye kugadzikana pakurwisa kupisa.Zvisinei, ine high sensitivity kune mavara machena uye brittleness yekutsamwa.Kusaverengeka kusingaverengeki, kunoda kudziya kwepamusoro-soro kusati kwapisa, kuzorora kwekunetseka mushure mekuputika, uye kushandiswa mushure mekupisa.

Application
Inowanzo shandiswa kugadzira zvikamu zvakakosha zvine simba rakakura uye yakanaka plastiki, uye yekugadzira zvikamu zvakakosha zvine zvakakosha zvinoshanda zvinodiwa mushure mekurapa nitrating:
-Makina anorema ane mashefu akakwira
-Wheel shaft ine dhayamita yakakura kupfuura 250mm
-Rotor shaft yeherikoputa
-Iyo turbine shaft, blades, uye yakakwirira mutoro wekutapurirana zvikamu zveinjini yeturbojet
- Crankshaft fasteners, magiya, nezvimwe.
Package
1.Nemasumbu, bundle rimwe nerimwe rinorema pasi pematani matatu, kune zviduku zvekunzedhayamita yakatenderedza bha, imwe neimwe bundle ine 4 - 8 simbi mitsetse.
2.20 tsoka mudziyo une dimension, kureba pasi pe6000mm
