X120Mn12 (Mn13) yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm siab thiab cov khoom siv nrog kev hnav tsis kam thiab kev ntxhov siab. High manganese steel muaj ob yam loj tshaj plaws: ua ntej, nws muaj kev cuam tshuam sab nraud ntau dua thiab zoo dua hnav tsis kam; Lwm tus yog kev tsim qauv txuas ntxiv ntawm cov kev ua yeeb yaj kiab Lamination ua lub ntsej muag zoo li dense lamination maj mam hnav. X120Mn12 (Mn13) forged steel phaj muaj kev hnav zoo heev rau kev hnav thiab kev ntxhov siab siab, thiab yuav tsis tawg thaum siv. Nws kuj muaj cov cuab yeej siv tshuab xws li kev txiav yooj yim, vuam, thiab khoov. High chromium forgings yog siv, uas tsuas muaj qhov zoo ntawm lub xov tooj ntawm tes.
X120Mn12 siab manganese hlau tshuaj muaj pes tsawg leeg:
Cov pa roj carbon C: 1.10-1.30;
Silicon Si: 030-0.50;
Manganese Mn: 11 00-14 00;
Sulfur S: Ntau dua lossis sib npaug rau 0.040;
Phosphorus P: Tsawg dua lossis sib npaug rau 0.100;
Chromium Cr: 1.50.
X120Mn12 siab manganese hlau Mechanical zog:
Tensile zog σ b (Mpa): 880-1130;
Yield zog Re (Mpa): Ntau dua lossis sib npaug rau 410;
Elongation tus nqi δ (％): Ntau dua lossis sib npaug rau 40;
Kev cuam tshuam qhov nqus Akv (J): 124 (ntawm chav tsev kub);
Hardness: Tsawg dua los yog sib npaug rau 229HB.
Siv rau qhov tsis zoo ntawm cov khoom siv qis kawg, txuag cov khoom siv kho dua tshiab thiab txhim kho kev sib tw.
11 feem pua rau 14 feem pua ntawm cov hlau manganese nrog cov khoom ua haujlwm zoo heev. Haum rau hnav daim ntaub ntawv uas muaj kev cuam tshuam siab / gouging coj los ua haujlwm nyuaj. X120Mn12 manganese steel phaj tuaj yeem txiav los ntawm cov ntshav lossis laser profile. Cov khoom no yog cov khoom tsis sib nqus, ua haujlwm hnyav hnav-resistant steel phaj, uas yog muab nyob rau hauv daim ntawv ntawm tag nrho cov phaj los yog txiav daim.
Kev tsim:
Kev sib sau tuaj yeem ua tiav yam tsis muaj qhov nyuaj, vim tias daim ntawv nyob rau hauv cov khoom siv muaj ductility. Txhawm rau kom tsis txhob tawg, cov npoo uas tau shear ua hauj lwm hardening yuav tsum tau chamfered thiab hauv av 2 mus rau 3 hli raws cov npoo yuav tsum tau tsim. Yog tias ua tau, kev tsim yuav tsum tau ua nyob rau hauv ib qho kev ua haujlwm kom tsis txhob ua haujlwm hnyav.
Drilling:
Txij li thaum cov ntsiab lus manganese yog 11 feem pua rau 14 feem pua, cov hlau manganese siab yog qhov nyuaj rau kev xyaum thiab yuav ua haujlwm sai sai. Lub tshuab hnyav thiab ruaj khov heev yuav tsum tau siv 8 feem pua cobalt high-speed steel armor tho tho tho, lossis nyiam dua cov tho tshwj xeeb nrog cov tawv tawv tawv tawv. Tsis txhob xuas nrig ntaus los yog cia lub laum me ntsis rub rau ntawm qhov chaw tsis pub noj, vim qhov no yuav ua rau muaj kev ua haujlwm nyuaj.
Vuam:
Vuam yuav tsum tau nqa tawm siv E308Mo hom austenitic stainless hlau consumables. Raws li lub siab manganese hlau nrog siab coefficient ntawm thermal expansion thiab tsawg coefficient ntawm thermal conductivity, vuam yuav tsum tau nqa tawm nyob rau hauv tsawg tshav kub nqi. Lub sij hawm ntev cia ntawm cov ntaub ntawv nyob rau hauv qhov kub ntawm 300 ° C mus rau 800 ° C tuaj yeem ua rau embrittlement vim carbide nag lossis daus.
