40CrNiMo Steel Round Bar

40CrNiMo intsimbi eshushu eqengqelekayo imivalo engqukuva

Intsimbi ye-40CrNiMoA yintsimbi yaseTshayina, inamandla amakhulu, ukuqina kunye nokuqina okulungileyo, kwaye inozinzo oluchasene nokushisa, kodwa inobuzwe obuphezulu be-white point, i-tender brittleness kunye ne-weldability embi. Ukushisa kwangaphambili kuyafuneka ngaphambi kwe-welding, kwaye unyango lokunciphisa uxinzelelo luyafuneka emva kwe-welding.

Intshayelelo yemveliso

Intsimbi ye-40CrNiMoA isetyenziswe emva kokucima kunye nokufudumala, kwaye isetyenziselwa ukwenza iindawo ezibalulekileyo ezifuna iplastiki efanelekileyo, amandla aphezulu kunye nobukhulu obukhulu. Ngokomzekelo, i-shafts enzima kumatshini onzima, i-shafts ye-injini ye-steam enobubanzi obungaphezulu kwe-250 mm, ii-blades, ii-transmissions, i-fasteners, i-crankshafts, i-gear, njl. °C.
I-Chrome-Moly low alloy steel series iqulethe i-0.5% - 9% Cr kunye ne-0.5% - 1% Mo kunye ne-0.20% yekhabhoni ephantsi. I-40CrNiMoA, i-4340 kunye ne-SNCM439 zizinto eziphantsi kwe-alloy chromoly steel materials ezivela kwimigangatho eyahlukeneyo.

I-4340 kunye ne-SNCM439 yimigangatho evela eMelika naseJapan ngokulandelelanayo. Kwiimeko ezininzi zinokuba zizixhobo ezizezinye, ngaphandle kokuba kukho inqaku elikhethekileyo okanye elisetyenziselwa injongo ekhethekileyo. Umahluko wabo ukho ikakhulu kwizinto zekhemikhali, iinkcukacha ziboniswe ngolu hlobo lulandelayo:

Imigangatho	GB	AISI	I-JIS
Izinto eziphathekayo	40CrNiMoA	4340	SNCM439(SNCM8)
C	0.37~0.44	0.38~0.43	0.36~0.43
Si	0.17~0.37	0.15~0.35	0.15~0.35
Mnu	0.50~0.80	0.60~0.80	0.60~0.90
P	≤0.025	≤0.035	≤0.030

Ireyithi yokunciphisa kwindawo: ≥55%
Impembelelo yokufunxa amandla: ≥ 78 J
IMaterial Brinell Hardness: ≤ 269 (Intonga yentsimbi efakwe kwi-annealed okanye ubushushu obuphezulu)
Ubungakanani besampuli: 25mm

Inkcazo yonyango lobushushu

Ukucima ubushushu bokuqala: 850 °C (Quenchant–oyile)
Ukufudumeza ubushushu bobushushu: 600 °C (Quenchant– amanzi, ioli)

Yayisetyenziswa apho kufuneka ipropathi eqinile kwaye ikwazi ukumelana nempahla efana nee-asi ezinzima, iishafti, iigiya ezisindayo, iintsimbi zokusonta, izikhonkwane, iibholiti, ii-couplings, ii-sprockets, iipinion, ii-torsion bars, iirodi zokuqhagamshela. Ezi ntsimbi ziphezulu zisetyenziswa kakhulu kwiindawo ezifana neshishini lepetroli yemichiza, iimoto, izixhobo zamandla omphunga kunye nezinye iinkonzo zobushushu obuphezulu.
