Dab tsi yog Free-Machining Steel?
Cov Hlau Txiav Dawb yog lub npe menyuam yaus rau cov hlau carbon nrog cov khoom sib xyaw ntxiv rau lub hom phiaj nkaus xwb los txhim kho lawv txoj kev siv tshuab thiab kev tswj cov chip. Lawv kuj tseem raug hu ua Cov Khoom Siv Txiav Dawb lossis Cov Khoom Siv Txiav Dawb.
Cov Hlau Uas Siv Tau Dawb Muab Faib Ua 3 Pawg Me
l11xx series: qhov ntau ntawm Sulfur (S) tau nce ntxiv los ntawm 0.05% hauv cov hlau carbon dawb mus rau 0.1%. Nws ntxiv txog 20% rau qhov kev siv tshuab thaum piv nrog cov ntaub ntawv sib npaug hauv 10xx series. Ntawm qhov tod tes, lub zog tensile txo qis los ntawm kwv yees li 10%, thiab cov khoom siv yog brittle dua.
l12xx series: Cov ntsiab lus ntawm sulfur (S) tau nce ntxiv mus rau 0.25%, thiab cov ntsiab lus ntawm Phosphorus (P) tau nce ntxiv los ntawm 0.04% hauv 10xx series mus rau 0.5%. Yog li ntawd, qhov kev siv tshuab tau nce ntxiv 40% ntawm tus nqi ntawm kev poob qis ntxiv hauv cov khoom siv kho tshuab.
lSAE 12L14 yog ib qho dawb txiav hlau qhov twg Phosphorus raug hloov los ntawm 0.25% ntawm Lead (Pb), uas ua rau muaj kev siv tshuab ntau dua 35%. Qhov kev txhim kho no tshwm sim vim tias Lead yaj hauv zos ntawm qhov chaw txiav, yog li txo qhov kev sib txhuam thiab muab cov roj nplua nyeem ntuj. Txawm li cas los xij, ntau lub tuam txhab tsim khoom siv thiab cov khw muag tshuab sim zam cov tshuaj ntxiv lead vim yog kev puas tsuaj rau ib puag ncig thiab kev pheej hmoo kev noj qab haus huv.
Yuav ua li cas xaiv cov hlau txiav dawb
Jindalai Steel yog ib lub tuam txhab tsim khoom, muag khoom, xa khoom, thiab faib cov khoom siv hlau xws li yeeb nkab, raj xa dej, pas nrig thiab pas nrig. Cov khoom hlau uas peb muab yuav tsum yog ua los ntawm cov khoom siv zoo tshaj plaws thiab muaj daim ntawv pov thawj raws li cov qauv kev lag luam xws li ASTM thiab ASME lossis lwm yam qauv.Jindalai Steel muab thiab khaws cov khoom lag luam loj ntawm ASTM 12L14, AISI 12L14, SAE 12L14 (SUM24L / 95MnPb28 /Y15Pb) cov khoom siv kho tshuab puag ncig xws li cov twj paj nruag thiab cov ntsuas, cov khoom siv saib, tsheb, cov cuab yeej tshuab thiab lwm yam tshuab ntawm kev siv cov khoom txheem, xws li bolts, cov cuab yeej txiav, bushing, pin, thiab cov ntsia hlau tshuab, yas molding, phais thiab kho hniav, thiab lwm yam.
