S355K2W siv EN 10025-5 tus qauv thiab yog ib qho kev txhim kho huab cua-resistant steel qauv. 2. Cov txheej txheem ntws yog:
High-quality kub hlau, KR kub hlau pretreatment, 100/120 tons saum thiab hauv qab tshuab converter, LF rauv refining, nqus degassing kev kho mob, slab txias rau 24-60 teev, pusher hom cua sov rauv, 3800m dov zeb, ACC laminar flow txias, 11-roller thermal straightening tshuab, stacking txias, xov, kev tshuaj xyuas sab nraud, tsis pom kev, thiab warehouses. Cov txiaj ntsig zoo ntawm qhov kev tsim kho tam sim no yog: tsis hloov cov pa roj carbon sib npaug ntawm cov tsoos S355K2W, los ntawm TMCP dov thiab steel phaj stacking qeeb txias Txoj kev no yuav xyuas kom meej tias cov hlau phaj ua tau raws li cov kev cai ntawm lub teb chaws cov qauv; Nyob rau tib lub sijhawm, cov txheej txheem ntau lawm yog yooj yim thiab cov txheej txheem kho cua sov raug tshem tawm.
3. S355K2W tus me nyuam raws li txoj cai:
S355K2W yog xa hauv kub dov, normalized lossis normalized dov mob.
4. Tensile zog:
(MPa): 450-600.
5. Lub zog cuam tshuam:
-20 degree: Ntau dua lossis sib npaug li 40J (phaj tuab tsawg dua 150mm)
6. Tshuaj muaj pes tsawg leeg:
C: {{0}}.08-0.15, Si: 0.20-0.45, Mn: 1.20-1.45, P Less tshaj lossis sib npaug rau 0.018, S Tsawg dua lossis sib npaug rau 0.{{20}}07, Als: 0.015-0 .050, Nb+V+Ti Tsawg dua lossis sib npaug li 0.15%, Cr: 0.45-0.70%, Cu: 0.30-0.50%,
7. Peb muaj peev xwm muab tau:
1. Muaj steel phaj specifications ntau yam: thickness 8-700mm, dav 1500-4020mm, ntev 4000mm-17000mm, unit hnyav txog 30.00 tons. Loj loj steel phaj kuj muaj raws li qhov kev thov.
2. Hom steel phaj muaj: carbon structural steel daim hlau, low-alloy high-strength steel daim hlau, steel daim hlau rau txuas hniav, steel daim hlau rau lub tsev, steel phaj rau shipbuilding thiab offshore platforms, steel phaj rau boilers thiab siab hlab ntsha, steel daim hlau rau pwm, alloy structural steel daim hlau, Muaj 12 pawg hlau phaj rau roj thiab roj xa cov kav dej, siab zog thiab siab tawv steel daim hlau, corrosion-resistant steel daim hlau, composite steel phaj, thiab lwm yam., nrog ntau tshaj 300 domestic thiab txawv teb chaws hom.
3. Muaj rau cov hlau phaj nrog qhov yuav tsum tau kuaj xyuas qhov tsis zoo, Z15-Z35 thickness kev taw qhia kev ua tau zoo, siab zog thiab siab toughness, thiab lwm yam.
4. tuaj yeem muab tau raws li lub teb chaws tus qauv, cov qauv hlau metallurgical, Asmeskas cov qauv AISI / ASME / ASTM, Japanese JIS, German qauv DIN, Fabkis NF, British BS, European EN, thoob ntiaj teb ISO thiab lwm yam qauv.
