SAE4140 SAE4130 SAE4340 Alloy Hot Rolled Round Steel Bar
SAE4140 alloy alloy round bar e na le ho thatafala ha matla le ho kenella ka thata, ka litaba tsa eona tsa chromium tse fanang ka boima bo botle le molybdenum e matlafatsang botsitso le botsitso. Thepa ena e arabela hantle kalafo ea mocheso 'me e bonolo ho e sebelisa ka har'a boemo ba annealed a batang.
SAE4130 Round Steel Bar
SAE4130 ke lisebelisoa tse tlase tsa alloy tse nang le karolo e phahameng ea chromium le molybdenum bakeng sa matla a matle le ho tiea.
E atisa ho sebelisoa ha ho etsoa likarolo le likarolo tse nang le litlhoko tse phahameng tsa matla, tse kang likarolo tsa mechine, lisebelisoa tsa enjene, liporo tsa tataiso, joalo-joalo indastering ea lifofane.
SAE4340 tšepe e pota-potileng ke lisebelisoa tsa tšepe tse entsoeng ka motsoako oa tšepe, tse leng tsa sehlopha sa Amerika sa ASTM A29, se lumellanang le 40CrNi2Mo ka Sechaena se tloaelehileng sa GB/T 3077-2015.
Likarolo tsa eona tsa mantlha li kenyelletsa khabone, silicon, manganese, nickel, molybdenum, joalo-joalo, tseo khabone e ka bang 0.38%, bokahare ba nickel bo pakeng tsa 1.65% le 2.00%, 'me ho eketsoa ha molybdenum ho matlafatsa ho tiea le ho hanyetsa kutu ea. tšepe.
SAE4340 tšepe e pota-potileng e na le mefuta e mengata ea lisebelisoa tsa ho etsa mechine, ho etsa likoloi, ho ntša oli le likarolo tse ling, haholo-holo ho etsoa ha li-drive shafts, likere, li-bearings le likarolo tse ling tsa bohlokoa tse nang le ts'ebetso e babatsehang.
Libaka tsa kopo le litšobotsi tsa ts'ebetso
Lisebelisoa tsena li sebetsa hantle ts'ebetsong ea phekolo ea mocheso, 'me ka mor'a phekolo e nepahetseng ea annealing, quenching le tempering, ba ka fumana boima bo loketseng, polasetiki le ho thatafala ho finyella litlhoko tsa tšebeliso tlas'a maemo a fapaneng a ho sebetsa.
Nakong ea mechine, boemo ba phekolo ea mocheso oa thepa bo lokela ho nkoa e le ho netefatsa boleng ba mochine le boreleli ba kopano e latelang.
