Cov lus piav qhia txog ntawm 40CR cov hlau hlau:
Cov Khoom Siv Khoom Siv Yooj Yim:
Qeb thiab Qauv
Suav Txheem: GB / T 3077-2015 (alloy qauv hlau)
Txuj Ci German: DIN 1.7045 (41CR4)
Sib raug rau Tebchaws Meskas: AISI 5140 (sib xyaw ua ke)
Qib Txhais:
40: Cov ntsiab lus carbon 0.40%
Cr: Chromium Cov Ntsiab Lus 0.80 - 1.10%
Cov yam ntxwv tseem ceeb:
Siab lub zog (tempered lub xeev σeb ntau dua los yog sib npaug rau 980 MPa)
Cov tawv tawv muaj zog tshaj plaws (cov cheeb tsam tseem ceeb rau roj quenching 25-40 mm)
Zoo heev qaug zog ua tau zoo, moderate machinability
Cov Ntawv Thov Raug Raug:
Neeg kho tshuab kis cov khoom siv, siv machinery, thiab tuam manactoring
Cov Nta Tseem Ceeb & Zoo:
• High tensile lub zog (ntau dua los yog sib npaug rau 980 MPa li-kos) thiab tawm lub zog (ntau dua los yog sib npaug zos rau 785 mpa)
• Cov Hnav Loj & qaug zog tsis kam tom qab kev kho cua sov
• Zoo heev machinability thiab txias-hau kev ua haujlwm rau kev kub ceev cov ntsia hlau
• Cov Khaub Ncaws Hnav Zoo Nkauj + Ferrite microstructure, qhov kev txwv tsawg dua lossis sib npaug rau 0.05 hli
• Xaiv cov nqi them rau 42crmo hauv nruab nrab kev ntxhov siab
Cov kev xaiv customization:
• Tsim: Cov Yeeb Yam Kev Cai
• Cov khoom siv: 40Cr, 40crmo, 40crv Micro-alloy rau kev ua kom muaj zog ntau dua
• Kev Kho Cua Sov: Kev kho cua sov: quenched & tempered, ntxhov siab-relieved
• Nto: Galvanized (8-25 μm), kub-dip Galvanized (40-120 μm), ZN-Al Alloy, Epoxy Primer
• Tshwj xeeb ntim: Cov kab yas yas, rooj ntoo, VCI zaj duab xis
Tswjhwm Zoo & Ntawv Pov Thawj:
Ntau Lawm Flow: EF-LF-LF-LF-VD → Nruam Rolling → Cov Khaub Ncaws Kub & Siv → Tensile kawg & Hardness Test.
