SPCC Txias -Rolled Carbon Steel Phaj (JIS G 3141)
SPCC (Steel Plate Cold Commercial) yog ib qho txias - dov qis- carbon steel phaj teev nyob rau hauv Japanese Industrial Standard (JIS). Nws yog dav siv hauv stamping, dabtsi yog khoov, vuam, thiab lwm yam kev siv. Hauv qab no yog cov ncauj lus kom ntxaws txog SPCC:
1. Kev sib piv tus qauv thiab qib
Standard Corresponding Grade Similar Qib (Lwm Lub Tebchaws)
JIS G 3141 SPCC Tuam Tshoj: SPCC (GB/T 5213)
US: ASTM A1008 CS Hom B
Teb chaws Europe: DC01 (EN 10130)
JIS G 3131 SPHC (Kub-Rolled Low-} Carbon Steel) Tuam Tshoj: SPHC (GB/T 5213)
Lus Cim: SPCC yog ib qho txias- dov steel phaj, thaum SPHC yog kub- dov steel phaj. Ob qhov sib txawv ntawm qhov zoo thiab kev ua haujlwm zoo.
2. Cov tshuaj muaj pes tsawg leeg yog dab tsi (raws li JIS G 3141)?
Cov ntsiab lus: C (Carbon) Mn (Manganese) P (phosphorus) S (Sulfur) Lwm yam
Cov ntsiab lus (%): Tsawg dua lossis sib npaug rau 0.12 Tsawg dua lossis sib npaug rau 0.50 Tsawg dua lossis sib npaug rau 0.040 Tsawg dua lossis sib npaug rau 0.045 Kab
Cov yam ntxwv: Cov pa roj carbon tsawg, tsis tshua muaj alloy, nrog zoo plasticity thiab weldability, tab sis tsis muaj zog.
3. Dab tsi yog cov khoom siv kho tshuab (JIS G 3141)?
Performance Parameters Cov Nqe Lus Cim
Tensile Strength (Rm) 270-410 MPa Tsawg zog, haum rau stamping.
Yield Strength (Rp0.2) Ntau dua lossis sib npaug rau 140 MPa Tej zaum yuav qis dua hauv lub xeev annealed.
Elongation (A50mm) Ntau dua lossis sib npaug li 28% -34% Thinner thickness nce elongation.
Hardness (HRB) 40-75 Hardness txo qis tom qab annealing.
Bending Properties 180℃khoov tsis muaj kab nrib pleb Haum rau khoov thiab stamping.
Lus Cim: Cov khoom siv kho tshuab raug cuam tshuam los ntawm cov khoom tuab thiab cov txheej txheem annealing. Cov ntaub ntawv tshwj xeeb yuav tsum tau hais txog hauv tus neeg muag khoom daim ntawv tshaj tawm.
4. Kev siv ntau
Stampings: Hluav taws xob vaj tse, automotive qhov chaw, kho vajtse
Sheet hlau ua: Chassis, brackets, npog
Welded Structural Parts: Tsawg-kev nyuaj siab welds (nco ntsoov deformation)
Lub hauv paus kho deg: Electroplating, tshuaj tsuag txheej, galvanizing (xws li SECC)
5. Kev kho deg thiab kev faib tawm
Nto Hom Code Nta Daim Ntawv Thov
Glossy SPCC-SD Smooth, nplai -dawb High-precision stamping
Matte SPCC-MAT Me ntsis ntxhib, haum rau tshuaj tsuag txheej General ntawv hlau
Galvanized SECC Enhanced xeb kuj Chassis, vaj tse
6. Kev sib piv nrog cov khoom zoo sib xws
Material Standard Features Applications
SPCC JIS G 3141 Txias- dov, du nto, zoo yas stamping, khoov
SPHC JIS G 3131 Kub- dov, ntxhib nto, me ntsis zog dua Cov yam ntxwv, tsis yog - precision machining
SECC JIS G 3313 Galvanized SPCC, corrosion{1}}resistant Chassis, sab nraum zoov
7. Kev yuav khoom thiab kev txiav txim siab yog dab tsi?
Thickness Range: Feem ntau muaj los ntawm 0.3mm txog 3.0mm, nrog rau kev kho kom haum rau ultra-nyias lossis ntxiv- cov ntawv tuab.
Annealed: softer tom qab annealing, haum rau sib sib zog nqus nqus; me ntsis siab zog nyob rau hauv lub zog (unannealed) lub xeev.
Vuam: Spot vuam thiab arc vuam siv tau, tab sis cov khoom siv hluav taws xob yuav tsum tau tswj kom tsis txhob deformation.
Kev tiv thaiv xeb: SPCC tsis muaj coated thiab raug xeb, yuav tsum tau roj lossis electroplating (xws li SECC).
Cov ntsiab lus: SPCC yog ib qho kev lag luam txias - dov, qis - carbon steel ntawv haum rau stamping, dabtsi yog khoov, thiab lwm yam txheej txheem, tab sis yuav tsum tau ceev faj tiv thaiv xeb. Rau siab zog los yog corrosion kuj, xav txog lwm yam ntaub ntawv xws li SPCD (rau stamping) thiab SECC (galvanized).
