1. Nyiv (JIS Standard)
FC Series: FC series hauv Nyij Pooj sawv cev rau qib cam khwb cia hlau, nrog cov lej qhia lub zog tensile. Txawm hais tias tsis yog cov hlau ntshiab, qee cov qib yuav muaj cov ntsiab lus tsis tshua muaj alloy, mus txog qhov muaj pes tsawg leeg ntawm cov hlau ntshiab. Piv txwv li,FC 100Nws muaj lub zog tensile ntawm kwv yees li 100 MPa. Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias cov no yog cov qib cam khwb cia hlau thiab tsis yog hlau ntshiab.
2. Tebchaws Asmeskas (ASTM Standard)
UNS K00001 (Electrolytic Hlau): Qib no sawv cev rau cov hlau electrolytic, uas yog ib hom high-purity hlau uas ua los ntawm electrolytic refining. Nws yog ze tshaj plaws rau cov hlau ntshiab hauv cov ntsiab lus ntawm cov qib steel uas muaj nyob hauv Tebchaws Meskas.
AISI 1000 Series (Wrought Hlau thiab Hlau): AISI 1000 series suav nrog carbon steels nrog cov ntsiab lus tsis tshua muaj alloy.TIAB SA 1008Piv txwv li, yog cov hlau tsis tshua muaj carbon nrog cov ntsiab lus ntawm kwv yees li 0.08%. Thaum tsis yog hlau ntshiab, nws yog ib qho ntawm cov qib ze tshaj plaws rau cov hlau ntshiab hauv cov ntsiab lus ntawm cov ntsiab lus ntawm cov hlau wrought.
3. Teb chaws Europe (EN Standard)
EN 10025 (Structural Steel): Cov qauv no suav nrog ntau qib ntawm cov qauv hlau. Thaum cov qib feem ntau muaj cov alloys los txhim kho cov khoom siv kho tshuab, qee qib, xws liS235 JR(ib qho tsis-alloy structural steel), muaj cov ntsiab lus tsis tshua muaj alloy. Txawm li cas los xij, lawv tseem tsis yog hlau ntshiab.
TS EN 10083 Case-hardening hlau: Cov qauv no suav nrog cov hlau tshwj xeeb uas tsim los rau cov txheej txheem nyuaj. Thaum cov qib no muaj cov ntsiab lus alloying rau hardening, qee qib, zoo li16MnCr5, muaj cov ntsiab lus tsis tshua muaj alloy piv rau lwm qib steel.
4. Russia (GOST Standard)
GOST Steels: Lavxias steel qib feem ntau muaj cov ntsiab lus alloying haum rau cov kev siv tshwj xeeb. Txawm li cas los xij, qee qib, xws li08 ps ib(cov hlau tsis muaj roj carbon tsawg), muaj qhov sib xyaw ze ntawm cov hlau ntshiab raws li cov ntsiab lus alloy.
5. Is Nrias teb (IS Standard)
YOG Steels: Indian qib steel kuj suav nrog ntau yam alloys tsim rau kev siv sib txawv. Txawm li cas los xij, qee qib, zoo liIB 2062 E250(cov hlau me me), muaj cov ntsiab lus tsis tshua muaj alloy, mus txog qhov sib xyaw ntawm cov hlau ntshiab tab sis tsis yog hlau ntshiab.
Lus Qhia Tseem Ceeb
Nws yog ib qho tseem ceeb kom nkag siab tias tsis muaj cov qib uas tau hais los saum no yog cov hlau ntshiab. Cov hlau ntshiab, nrog rau qhov muaj pes tsawg leeg ntawm ze li ntawm 100% Fe, yog tsis tshua muaj siv nyob rau hauv cov ntawv thov kev lag luam vim nws cov khoom siv tshuab tsawg. Hloov chaw, steels thiab cam khwb cia hlau yog cov hlau alloys nrog ntau yam ntxiv los txhim kho lawv cov khoom. Cov qib uas tau hais yog qhov ze tshaj plaws rau cov hlau ntshiab hauv cov ntsiab lus ntawm cov ntsiab lus ntawm cov hlau uas muaj ntau thiab cov cam khwb cia hlau.
Rau cov ntawv thov tshwj xeeb uas xav tau cov hlau purity siab, cov khoom siv xws li cov hlau electrolytic lossis cov hlau nqus-melted, tab sis cov no feem ntau tsis them los ntawm cov qib steel qauv.
