Weathering steel phaj:

Weathering structural steel yog atmospheric corrosion-resistant steel, uas belongs rau low-alloy high-strength structural steel.Raws li nws cov yam ntxwv tseem ceeb, nws tau muab faib ua huab cua huab cua thiab huab cua steel rau cov qauv welded.

Kev faib tawm:

High weathering steel

Cov huab cua tiv thaiv cov qauv hlau yog ntxiv me me ntawm tooj liab, phosphorus, chromium thiab npib tsib xee rau cov hlau los tsim cov txheej txheem tiv thaiv ntawm cov hlau sib sau los txhim kho atmospheric corrosion kuj ntawm cov hlau, thiab ib qho me me ntawm cov hlau. molybdenum, niobium, Vanadium, titanium, zirconium thiab lwm yam khoom siv los kho cov nplej, txhim kho cov khoom siv ntawm cov hlau, txhim kho lub zog thiab tawv ntawm cov hlau, txo qhov kev hloov pauv kub, thiab ua kom nws muaj kev tiv thaiv zoo dua rau nkig. tawg.

Weathering steel rau ob welded qauv

Cov ntsiab lus ntxiv rau cov hlau, tshwj tsis yog phosphorus, yog qhov pib zoo ib yam li cov huab cua tiv thaiv cov qauv hlau, thiab lawv cov dej num kuj zoo ib yam, thiab txhim kho vuam kev ua tau zoo.

siv:

Kev siv cov txheej txheem huab cua siab yog siv rau bolted, riveted thiab welded yam ntxwv qhov chaw rau tsheb, ntim, tsev, yees thiab lwm yam qauv vim nws zoo atmospheric corrosion tsis kam tshaj weathering steel rau welded lug.Thaum siv los ua cov txheej txheem welded, lub thickness ntawm cov hlau yuav tsum tsis pub tshaj 16 hli.Qhov kev ua tau zoo ntawm cov huab cua steel rau cov qauv welded yog zoo dua li cov huab cua huab cua siab, thiab nws yog siv rau cov khoom siv welded ntawm cov choj, cov tsev thiab lwm yam qauv.
