1. Dab tsi yog ovtm 519 1035 cov yeeb nkab steel?
A: ASTM A519 yog American tus qauv rau seamless neeg kho tshuab steel yeeb nkab steel yeeb nkab-carbon steel nrog cov pa roj carbon nrog li 0.35%. Cov yeeb nkab steel no yuav tsum tau ua kom tau cov tshuaj sib xyaw ua ke, cov cuab yeej siv txhua lub tsev, thiab muaj kev nkag rau hauv machining, tshuab siv hydraulic, thiab lwm yam kev siv.
2. Dab tsi yog cov tshuaj lom neeg muaj pes tsawg leeg ntawm 1035 steel?
A (Ntau Yam Tseem Ceeb):
Cov pa roj carbon (c): 0.32% -0.38%
Manganese (MN): 0.60% -0.90%
Phosphorus (P), Sulfur (s): tsawg dua los yog sib npaug rau 0.040% (txhua)
Silicon (si): 0.15% -0.35%
3. Dab tsi yog cov khoom ntiag tug cov khoom siv rau 1035 steel yeeb nkab?
Teb (ASTM A519 cov lus qhia tshwj xeeb):
Lub zog tensile: ntau dua los yog sib npaug rau 515 MPa
Paib lub zog: ntau dua lossis sib npaug nrog 400 MPA
Elongation: ntau dua los yog sib npaug rau 10% (50 hli gauge ntev)
Hardness: kwv yees li 137-179 HB (Brinell Hardness)
4. Dab tsi yog cov ntawv thov tseem ceeb?
Teb:
Tshuab Cheebtsam (Shafts, iav Blanks)
Cov kheej kheej kheej kheej, kheej kheej kheej, tsheb sib kis hauv tsheb
Cov qauv kav dej (xav tau vuam lossis txias ua haujlwm)
5. Dab tsi yog qhov txawv ntawm AISI 1035 thiab ASTM A519?
Teb: AISI 1035 yog cov ntaub ntawv tsim, thaum Astm A519 yog cov khoom siv steel hlau raug. A 519 1035 yog kev ua yeeb nkab ntxiv, nyob sab hauv, thiab kev ua phem rau eddy lossis ultrasonic).
