1215 dawb txiav steel
Tus txheej txheem tswj hwm: Asmeskas tus qauv ASTM A29 / A29M -04
1215 yooj yim txiav hlau yog cov khoom siv zoo ib puag ncig uas, piv rau 12L14, tsis muaj cov hmoov txhuas lossis cov khoom tsis zoo rau ib puag ncig. Nws muaj kev ua haujlwm zoo thiab tsim nyog rau cov khoom siv hluav taws xob dav dav, cov ntaub ntawv txiav, thiab cov khoom siv dav dav. Vim nws qhov tseeb raug thiab qhov zoo ntawm qhov chaw, cov khoom siv hlau yooj yim tuaj yeem siv ncaj qha, xws li txau, xuab zeb, khoov, drilling, thiab tseem tuaj yeem electroplated ncaj qha tom qab precision kos duab raws li qhov yuav tsum tau ua, txuag ntau lub sijhawm ua haujlwm thiab tus nqi ntawm configuring processing machinery.
Tshuaj muaj pes tsawg leeg:
C : Tsawg dua lossis sib npaug rau 0.09
Mn :075-1.05
SI: Tsawg dua lossis sib npaug rau 0.10
P :0.04-0.09
S :026-0.35
Mechanical zog:
tensile zog σ b (MPa): Ntau dua lossis sib npaug rau 42
yield zog σs (MPa): -
elongation δ 5 (%) : Ntau dua lossis sib npaug 22
Qhov txo qis ntawm cheeb tsam ψ (%) : Ntau dua lossis sib npaug rau 34
Hardness: Tsawg dua los yog sib npaug rau 160HB
Delivery status:
Round steel dub tuav tseem hu ua kub dov hlau.
Txias rub lub teeb pas nrig: Lub hardness tuaj yeem ncav cuag 160 ~ 190HB, txuag cov nqi kho cua sov thiab tso cai rau kev ua haujlwm ncaj qha.
Polishing pas nrig: nto roughness ntxiv los yog rho tawm 0.05
Lub hom phiaj:
Feem ntau yog siv los ua cov cuab yeej thiab ntsuas ntsuas, saib qhov chaw, tsheb, cov cuab yeej siv tshuab, thiab lwm yam tshuab nrog cov kev cai nruj rau qhov loj thiab ua tiav vim muaj kev ntxhov siab tsawg. Cov txheej txheem uas yuav tsum tau nruj me ntsis rau qhov raug thiab ua tiav tab sis kuj tsis tshua muaj kev ua tau zoo, xws li lub zog, ncej, bolts, li qub, bushings, pins, yeeb nkab txuas, lub caij nplooj ntoos hlav, lub rooj zaum, tshuab cuab yeej screws, yas molds, kev phais thiab kev kho hniav, lwm.
