SAE4340 Steel Round Bar ASTM4340 Steel Rod
Iimbonakalo
Izinto eziphathekayo ze-4340 zentsimbi yintsimbi yesakhiwo se-alloy.Ilingana ne-German DIN steel grade 36CrNiMo4, i-French NF standard 40NCD3, i-Japan JIS standard SNCM439, iBritish BS standard 816M40, American SAE / ASTM4340, American UNS standard G43400，China Standard 40CrNiMoA.
I-SAE4340 yaziwa ngokuba yintsimbi yolwakhiwo lwealloyi okanye intsimbi edibeneyo.Insimbi iqulethe i-nickel phakathi kwe-1.65 kunye ne-2.00, enamandla amakhulu, ukuqina, amandla aphezulu okuqina, kunye nokuzinza ngokuchasene nokushisa.Nangona kunjalo, inovakalelo oluphezulu kumabala amhlophe kunye nobushushu bomsindo.Ukungafundeki kakuhle, kufuna ukufudumeza okuphezulu kobushushu phambi kwe-welding, ukukhululeka koxinzelelo emva kwe-welding, kunye nokusetyenziswa emva kobushushu.
UMGANGATHO: ASTM A29/A29M-2012 okanye SAE J404

Iinkcukacha zonyango lobushushu
Icinywe kwi-850 ℃, ioli ipholile;Ubushushu kwi-600 ℃, amanzi apholisiwe, i-oyile ipholile.
Isicelo
Ngokuqhelekileyo isetyenziselwa ukuvelisa iindawo ezibalulekileyo ezinamandla aphezulu kunye neplastiki efanelekileyo, kunye nokwenza iindawo ezibalulekileyo ezineemfuno ezikhethekileyo zokusebenza emva konyango lwe-nitrate:
-Oomatshini abanzima abaneeshafu zomthwalo ophezulu
-I-Wheel shaft enobubanzi obungaphezulu kwe-250mm
-I-rotor shaft ye-helicopter
-Ishafti yeinjini yomoya, iiblades, kunye namalungu othumelo oluphezulu lomthwalo we-injini ye-turbojet
-Izibophelelo zeCrankshaft, iigiya, njl.
Iphakheji
1.Ngeenyanda, ubunzima bomthwalo ngamnye ngaphantsi kweetoni ezi-3, kubangaphandle ezincinciububanzi bar ngeenxa zonke, inyanda nganye kunye 4 - 8 imicu yentsimbi.
I-2.20 yeenyawo zesikhongozeli iqulethe i-dimension, ubude obungaphantsi kwe-6000mm
I-3.40 yeenyawo zesikhongozeli iqulethe i-dimension, ubude obungaphantsi kwe-12000mm
4.Ngenqanawa enkulu, intlawulo yoThutho iphantsi ngomthwalo omninzi, kwaye inkuluiisayizi ezinzima azinakulayishwa kwizikhongozeli ezinokuhanjiswa ngenqanawa ngomthwalo omninzi
Iphakheji
