Structural Steel S550GD Phaj vs S355JR Phaj: Qhov Tseem Ceeb Qhov txawv
Qhov sib piv tshaj plaws yog nruab nrabSteel Qauv S550GD phajthiab S355JR, siv dav dav hlau qauv:
| Feature | Steel Qauv S550GD phaj | S355JR Phaj |
|---|---|---|
| Yield zog | Ntau dua lossis sib npaug li 550 MPa | Ntau dua lossis sib npaug li 355 MPa |
| Tensile zog | 600-730 MPa | 470-630 MPa |
| Corrosion Resistance | Zoo heev (galvanized) | Basic (tsis muaj coated) |
| Daim ntawv thov | High -load qauv, hnyav ib puag ncig | Kev siv cov qauv siv dav dav, ib puag ncig me me |
| Nqe (2026) | $850-$950/ton | $700-$800/ton |
| Qhov hnyav Efficiency | Siab dua (thinner daim hlau rau tib lub load) | Lower (yuav tsum tau daim hlau tuab) |
S550GD yog qhov zoo tshaj plaws thaum lub zog thiab kev tiv thaiv corrosion yog qhov tseem ceeb, thaum S355JR yog tus nqi ntau dua - siv tau rau cov ntawv thov tsawg dua.
Steel Qauv S550GD phaj vs. S460MC phaj: Kev sib piv
Lwm qhov kev sib piv tseem ceeb yog nrog S460MC, qhov nruab nrab - lub zog steel qauv:
| Performance Metric | Steel Qauv S550GD phaj | S460MC Phaj |
|---|---|---|
| Yield zog | 550 MPa yam tsawg kawg nkaus | 460 MPa yam tsawg kawg nkaus |
| Formability | Zoo (tsim rau khoov / sib sau) | Zoo heev (zoo dua txias txias) |
| Weldability | Zoo (tsis muaj preheating yuav tsum tau rau nyias daim hlau) | Zoo heev (zoo weldability) |
| Corrosion Resistance | Siab (kub-dip galvanized) | Nruab nrab (tsis muaj coated) |
| Kev thov kom haum | Heavy- cov qauv thauj khoom, siv sab nraum zoov | Machinery thav duab, automotive Cheebtsam |
S550GD muaj zog dua, thaum S460MC muab cov qauv zoo dua rau cov duab nyuaj.
Chemical Comparison Table
Cov tshuaj muaj pes tsawg leeg sib txawv ntawm cov qib no qhia txog lawv qhov kev ua tau zoo sib txawv:
| Element | S550GD (Max, %) | S355JR (Max, %) | S460MC (Max, %) |
|---|---|---|---|
| Cov pa roj carbon (C) | 0.18 | 0.21 | 0.18 |
| Manganese (Mn) | 2.00 | 1.60 | 1.70 |
| Silicon (Si) | 0.50 | 0.55 | 0.40 |
| Phosphorus (P) | 0.030 | 0.035 | 0.025 |
| Sulfur (S) | 0.025 | 0.035 | 0.025 |
Cov kev sib txawv no ua rau muaj qhov sib txawv ntawm lub zog thiab kev ua tau zoo ntawm txhua qib.
Thaum Xaiv Cov Qauv Hlau S550GD Phaj
Steel Qauv S550GD phajyog qhov kev xaiv zoo tshaj plaws hauv cov xwm txheej hauv qab no:
Cov phiaj xwm xav tau lub zog siab - rau - qhov hnyav piv (txo tag nrho cov qauv hnyav)
Cov txheej txheem sab nraum zoov raug cov dej noo, av noo, lossis corrosive ib puag ncig
Thauj khoom-cov kabmob xws li kab teeb, kab, thiab trusses hauv cov tsev lag luam / kev lag luam
Infrastructure tej yaam num xws li choj, txoj kev loj, thiab kis tau tus yees
Cov ntawv thov uas lub neej ua haujlwm ntev thiab kev saib xyuas qis yog qhov tseem ceeb
Nws cov galvanized txheej tshem tawm qhov xav tau rau kev tiv thaiv corrosion ntxiv, txo cov nqi ntawm qhov project.
