Kev sib xyaw
Hlau ntshiab:
Muaj feem ntau ntawm cov hlau (Fe) nrog cov impurities tsawg.
Nws yog ib qho yooj yim hlau nrog ib tug high degree ntawm purity.
SAE 12L14 hlau:
Cov pa roj carbon tsawg, tsis muaj hlau lead-dawb txiav hlau nrog cov tshuaj muaj pes tsawg leeg.
Cov ntsiab lus tseem ceeb suav nrog carbon (C) Tsawg dua lossis sib npaug rau {{0}}.15%, manganese (Mn) 0.851.15%, sulfur (S) 0.26{{0}}.35%, phosphorus (P) 0.04{{0}}.09%, thiab lead (Pb) 0.150.35%.
Silicon (Si) cov ntsiab lus tsawg heev, tsis pub tshaj 0.05%.
Cov khoom
Hlau ntshiab:
High ductility thiab malleability.
Zoo hluav taws xob thiab magnetic conductivity.
Tsawg tensile zog thiab hardness.
Yooj yim rau xeb thiab corrosion tsis muaj kev kho kom raug.
SAE 12L14 hlau:
Cov machinability zoo heev vim muaj cov hlau lead, uas ua raws li cov roj nplua nyeem thaum txiav.
Cov khoom siv zoo nrog lub zog tensile xws li 390 MPa rau 755 MPa (nyob ntawm kev kho cua sov thiab qhov loj).
Elongation tsawg kawg yog 22% (kub-dov) thiab 7.0% (txias-dov).
Hardness tuaj yeem sib txawv ntawm 121 HB (kub-kub) mus rau 163 HB (txias-kos), nrog txias-draw hardness xws li 152 HB txog 217 HB.
Zoo plasticity thiab toughness, tso cai rau loj deformations yam tsis muaj cracking.
Resistant hnav thiab tsim kua muag, ua rau nws haum rau daim ntaub ntawv uas yuav tsum tau precision thiab durability.
Daim ntawv thov
Hlau ntshiab:
Siv nyob rau hauv hluav taws xob thiab sib nqus daim ntaub ntawv vim nws high conductivity.
Siv nyob rau hauv kev tsim cov hlau thiab lwm yam alloys.
Kev txwv tsis pub siv rau hauv cov qauv siv vim nws lub zog tsis tshua muaj zog thiab muaj kev cuam tshuam rau corrosion.
SAE 12L14 hlau:
Dav siv nyob rau hauv machinery, zog, metallurgy, aerospace, thiab lwm yam lag luam.
Qhov zoo tshaj plaws rau kev tsim cov cuab yeej precision, saib qhov chaw, cov khoom siv hauv tsheb, cov cuab yeej siv tshuab, cov khoom siv kho vajtse, cov rooj tog hlau, cov khoom siv hluav taws xob, thiab lwm yam uas yuav tsum tau muaj siab precision thiab nto tiav.
Haum rau cov ntawv thov uas xav tau kev ua haujlwm zoo, qhov tseeb qhov tseeb, thiab qhov zoo ntawm qhov chaw.
