1. Dab tsi yog ovtm 519 1030 cov yeeb nkab steel?
A: ASTM A519 yog tus qauv Asmeskas rau Seamless Carbon thiab Alloy}}}}}}}}}}}} Cov ntsiab lus ntawm cov khoom siv roj carbon me muaj li 0.30%. Hom yeeb nkab tshiab no yog tsim los ntawm cov txheej txheem txias lossis kub yob cov txheej txheem thiab muaj cov khoom muaj siab thiab cov khoom siv neeg kho tshuab siab. Nws yog feem ntau siv nyob rau hauv cov neeg kho tshuab cov txheej txheem, cov tshuab hydraulic, thiab lwm yam kev siv.
2. Dab tsi yog cov tshuaj lom neeg muaj pes tsawg leeg ntawm 1030 tus hlau?
A: Cov neeg muaj pes tsawg leeg ntau (feem pua phaus):
Cov pa roj carbon (c): 0.28-0.34%
Manganese (MN): 0.60-0.90%
Phosphorus (p) Tsawg dua lossis sib npaug rau 0.040%, Sulfur (s) tsawg dua lossis sib npaug rau 0.050%
Residual cov ntsiab xws li silicon (si) yuav nyob rau hauv kab lw cov nqi.
3. Dab tsi yog cov khoom ntiag tug ua haujlwm rau 1030 tus yeeb nkab steel?
Teb (siv cov khaub thuas-kos-kos ua piv txwv):
Lub zog tensile: ntau dua los yog sib npaug rau 515 MPa (75 KSI)
Paib lub zog: ntau dua los yog sib npaug nrog 400 mpa (58 ksi)
Elongation: ntau dua los yog sib npaug rau 10% (gauge ntev 50mm).
(Kub-dov lub zog yog qis dua me ntsis; thov saib rau cov lus txheem tshwj xeeb.)
4. Dab tsi yog cov ntawv thov tseem ceeb?
Teb:
Kev Raug Machinery (Shafts, Iav Blank)
Cov kheej kheej kheej kheej, kheej kheej kheej, tsheb sib kis hauv tsheb
Cov txheej txheem dav dav (qhov chaw vuam lossis tshuab luam ntawv yuav tsum tau).
5. Dab tsi yog qhov sib txawv ntawm AISI 1030 STEEL thiab ASTM A519 hlau?
Teb: AISI 1030 yog cov ntaub ntawv tsim, thaum ATTM A519 yog cov khoom siv hlau yeeb. 519 1030 cov yeeb nkab yuav tsum ua kom muaj kev sib tw nyob sab nraud, thiab kuaj qhov kev kuaj mob (xws li AISI 1030 tsuas yog txhais cov tshuaj muaj pes tsawg leeg thiab cov khoom tseem ceeb.
6. Cov kev kho mob li cas? A:
Deg dub (tsis kho tom qab kub yob)
Khaub thuas-kos qaim saum npoo (du, nplai-dawb)
Tuaj yeem tom qab galvanized, phosphated, lossis roj rau xeb tiv thaiv.
