1. Kev taw qhia luv luv ntawm S355J0W steel phaj:
S355J0W yog European tus qauv atmospheric corrosion-resistant steel, uas belongs rau huab cua-resistant steel phaj.Nws yog cov hlau tsis tshua muaj hlau ua los ntawm kev ntxiv qee yam ntawm cov hlau alloy rau cov hlau zoo tib yam.Lub atmospheric corrosion kuj ntawm weathering steel yog 2-8 npaug ntawm cov pa roj carbon zoo tib yam, thiab nws muaj cov khoom siv zoo, vuam zog, thiab lwm yam, thiab lub sijhawm ntev dua, qhov pom tseeb dua cov nyhuv corrosion.
2. S355J0W txhim kho atmospheric corrosion resistant steel
Ib qho ntawm cov ntsiab lus alloying ntxiv rau cov hlau, xws li P, Cu, Cr, Ni, Mo, txhawm rau txhawm rau txhawm rau tiv thaiv huab cua corrosion, thiab nyob rau hauv kev cuam tshuam ntawm huab cua, kev tiv thaiv tsis siv neeg oxide yuav rov ua dua tshiab. lub hauv paus hlau.
3. Kev xa khoom ntawm S355J0W:
Muab nyob rau hauv kub dov, normalized los yog normalized dov mob.
Plaub, S355J0W steel phaj tus qauv:
S355J0W siv EN10025-5: 2004 tus qauv.
5. S355J0W txhim kho atmospheric corrosion resistant steel
Ib qho ntawm cov ntsiab lus alloying ntxiv rau cov hlau, xws li P, Cu, Cr, Ni, Mo, txhawm rau txhawm rau txhawm rau tiv thaiv huab cua corrosion, thiab nyob rau hauv kev cuam tshuam ntawm huab cua, kev tiv thaiv tsis siv neeg oxide yuav rov ua dua tshiab. lub hauv paus hlau.
6. Peb muaj peev xwm muab tau:
1. Muaj steel phaj specification ntau yam: thickness 8-700mm, dav 1500-4020mm, ntev 4000mm-17000mm, unit hnyav txog 30.00 tons.Cov ntawv loj dua 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, steel phaj rau cov qauv hlau, Muaj 12 pawg hlau phaj rau cov roj thiab cov kav dej, muaj zog thiab siab tawv steel phaj, corrosion-resistant steel daim hlau, thiab cov phaj hlau sib xyaw, nrog ntau tshaj 300 hauv tsev thiab txawv teb chaws hom.
3. Muaj rau qhov yuav tsum tau kuaj xyuas qhov tsis zoo, Z15-Z35 thickness kev taw qhia kev ua tau zoo, siab zog thiab siab toughness yuav tsum thiab lwm yam steel phaj.
4. Nws tuaj yeem muab tau raws li cov qauv hauv teb chaws, cov qauv hlau metallurgical, Asmeskas cov qauv AISI / ASME / ASTM, Japanese JIS, German tus qauv DIN, Fabkis NF, British BS, European EN, thoob ntiaj teb ISO thiab lwm yam qauv.
Xya, S355J0W steel phaj tshuaj muaj pes tsawg leeg (smelting tsom xam) thiab S355J0W txhua yam khoom thiab cov khoom siv kho tshuab:
