16MnR High Tensile Steel Phaj

Lub 16MnR siab tensile steel phaj yog dav siv nyob rau hauv ntau yam kev lag luam daim ntaub ntawv vim nws cov tshuaj lom neeg muaj pes tsawg leeg thiab txhua yam khoom. Kev nkag siab txog cov ntsiab lus no yog qhov tseem ceeb rau cov engineers thiab cov kws tshawb fawb txog cov khoom siv los txiav txim siab paub txog kev siv nws.

Cov tshuaj muaj pes tsawg leeg ntawm 16MnR steel phaj feem ntau suav nrog cov hauv qab no:

• Cov pa roj carbon (C): Tam sim no nyob rau hauv tus nqi tswj, feem ntau yog li ntawm kwv yees li ntawm {{0}}.12% mus rau 0.20%. Cov pa roj carbon monoxide ua rau lub zog thiab hardness ntawm cov hlau.

• Manganese (Mn): Manganese cov ntsiab lus nyob rau hauv 16MnR steel yog feem ntau nyob rau hauv thaj tsam ntawm 1.20% mus rau 1.60%. Nws pab txhim kho hardenability thiab tensile lub zog ntawm cov khoom.

• Silicon (Si): Feem ntau pom nyob rau hauv ib feem ntawm li ntawm {{0}}.20% mus rau 0.55%. Silicon txhim kho lub zog thiab oxidation tsis kam ntawm cov hlau.

• Sulfur (S) thiab Phosphorus (P): Cov ntsiab lus no suav hais tias yog impurities thiab khaws cia nyob rau theem qis, feem ntau tsawg dua {{0}}.035% rau sulfur thiab 0.030% rau phosphorus, kom ntseeg tau tias cov neeg kho tshuab zoo khoom thiab weldability.

Cov khoom siv kho tshuab ntawm 16MnR steel phaj yog qhov tseem ceeb thiab txiav txim siab nws qhov tsim nyog rau kev siv sib txawv. Lub zog tensile ntawm 16MnR steel feem ntau yog li ntawm 510 txog 640 MPa. Qhov no qhia tau hais tias cov khoom muaj peev xwm los tiv thaiv stretching rog yam tsis muaj kev puas tsuaj. Lub zog tawm los, uas sawv cev rau qhov kev ntxhov siab uas cov khoom pib deform plastically, feem ntau yog nyob rau hauv thaj tsam ntawm 345 txog 390 MPa.

Lub elongation ntawm kev tawg yog ib qho tseem ceeb ntsuas ntawm cov khoom ductility. Rau 16MnR steel, qhov elongation feem ntau yog li ntawm 21% mus rau 25%. Lub elongation ntau dua qhia tau hais tias muaj peev xwm zoo dua ntawm cov khoom siv los ua cov yas deformation ua ntej tsis ua hauj lwm, uas yog qhov xav tau hauv ntau daim ntawv thov kom haum rau cov khoom thauj lossis deformations.

Qhov cuam tshuam ntawm 16MnR steel tseem yog qhov tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas cov khoom yuav raug rau dynamic lossis poob siab loading. Lub Charpy V-notch cuam tshuam lub zog ntawm qhov ntsuas kub, xws li chav tsev kub lossis qis dua, muab qhov qhia txog cov khoom muaj peev xwm tiv taus cov pob txha tawg.

Lub hardness ntawm 16MnR steel tuaj yeem sib txawv nyob ntawm kev kho cua sov thiab kev ua haujlwm. Feem ntau hardness qhov tseem ceeb ntawm kwv yees li 120 txog 170 HB.

Kev sib xyaw ua ke ntawm nws cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab ua rau 16MnR steel phaj haum rau ntau yam kev siv, suav nrog cov hlab ntsha siab, boilers, thiab cov khoom siv hauv kev tsim khoom thiab kev lag luam. Txawm li cas los xij, nws yog ib qho tseem ceeb kom ntseeg tau tias cov khoom siv tau ua tiav thiab tsim kom raug kom ua tiav cov khoom siv kho tshuab thiab kev ua tau zoo hauv cov khoom kawg.

Tsis tas li ntawd, thaum siv 16MnR steel, nws yuav tsum tau txiav txim siab txog yam xws li kev ua haujlwm ib puag ncig, chaw thau khoom, thiab cov txheej txheem tsim los ua kom lub neej ntev thiab kev ntseeg siab ntawm cov khoom tsim los ntawm cov khoom siv no. Kev tshawb fawb tsis tu ncua thiab kev txhim kho hauv kev tshawb fawb cov ntaub ntawv txuas ntxiv txhim kho peb txoj kev nkag siab ntawm cov khoom thiab kev ua tau zoo ntawm 16MnR steel thiab cov ntaub ntawv zoo sib xws, ua rau muaj txiaj ntsig zoo thiab kev nyab xeeb engineering tsim.
