Dab tsi yog Free-Machining Steel?
Free-Cutting Steel yog lub npe menyuam yaus rau carbon steel nrog cov ntsiab lus alloying ntxiv rau tib lub hom phiaj ntawm kev txhim kho lawv cov machinability thiab nti tswj. Lawv kuj muaj npe hu ua Free-Cut lossis Free-Cutting material.
Dawb-Machining Steels muab faib ua 3 pawg
l11xx Series: Tus nqi ntawm Sulfur (S) yog nce los ntawm 0.05% hauv cov pa roj carbon steels mus rau 0.1%. Nws ntxiv txog 20% rau lub machinability thaum piv nrog cov khoom sib npaug hauv 10xx series. Ntawm qhov tod tes, lub zog tensile txo li ntawm 10%, thiab cov khoom yog nkig.
l12xx Series: Sulfur (S) cov ntsiab lus yog ntxiv rau 0.25%, thiab Phosphorus (P) cov ntsiab lus tau nce los ntawm 0.04% hauv 10xx series mus rau 0.5%. Raws li qhov tshwm sim, lub machinability nce ntxiv 40% ntawm tus nqi ntawm kev poob qis ntxiv hauv cov khoom siv kho tshuab.
lSAE 12 L14 yog dawb txiav hlau qhov twg Phosphorus hloov los ntawm 0.25% ntawm Lead (Pb), uas txhawb nqa lub machinability los ntawm lwm 35%. Qhov kev txhim kho no tshwm sim vim tias Lead melts hauv zos ntawm qhov chaw ntawm kev txiav, yog li txo kev sib txhuam thiab muab cov roj ntsha ntuj. Txawm li cas los xij, ntau lub tuam txhab cov khoom lag luam thiab cov khw muag khoom sim ua kom tsis txhob muaj cov tshuaj txhuas txhuas vim kev puas tsuaj ib puag ncig thiab kev pheej hmoo ntawm kev noj qab haus huv.
Yuav xaiv cov hlau txiav dawb li cas
Jindalai Steel yog ib lub chaw tsim khoom thiab ua cov hlau ua lag luam, cov chaw muag khoom, cov neeg xa khoom, cov khoom lag luam ntawm cov khoom siv steel hlau xws li yeeb nkab, tubing, bar thiab pas nrig. Cov khoom lag luam steel muab los ntawm peb yuav tsum tau tsim los ntawm cov khoom siv zoo raw khoom thiab muaj ntawv pov thawj tag nrho rau kev lag luam tshwj xeeb xws li ASTM thiab ASME lossis lwm yam qauv.Jindalai Steel muab thiab npaj cov khoom muag loj ntawm ASTM 12L14, AISI 12L14, SAE 12L14 (SUM24L / 95MnPb28 / Y15Pb) round bar mechanical qhov chaw xws li ntsuas thiab ntsuas, saib qhov chaw, tsheb, tshuab cuab yeej thiab lwm yam tshuab ntawm kev siv cov khoom txheem, xws li bolts, tej cuab yeej, bushing, tus pin, thiab lub tshuab ntsia hlau, yas molding, phais thiab kho hniav khoom, thiab lwm yam.
