Tuam Tshoj Chaw tsim tshuaj paus Huab cua-resistant Structural Steel Phaj rau Tsev Kho Kom Zoo Nkauj
(1) 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 kev ua haujlwm ntawm cov hlau tiv thaiv atmospheric corrosion.Koj tuaj yeem ntxiv me me ntawm molybdenum, niobium, cov ntsiab lus xws li vanadium, titanium thiab zirconium tuaj yeem ua kom zoo dua cov nplej, txhim kho cov khoom siv hlau, txhim kho lub zog thiab tawv ntawm cov hlau, txo qhov kev hloov pauv kub, thiab ua kom nws muaj zog. zoo dua tsis kam rau brittle puas.
(2) Weathering steel rau welded qauv
Cov ntsiab lus ntxiv rau cov hlau, tshwj tsis yog cov phosphorus, yog qhov pib zoo ib yam li cov huab cua tiv thaiv cov qauv hlau, thiab muaj cov haujlwm zoo ib yam li nws, thiab txhim kho kev ua haujlwm vuam.
Kev siv cov huab cua tiv thaiv cov qauv hlau zoo dua li huab cua tsis kam hlau rau welded qauv vim nws cov atmospheric corrosion kuj.Nws yog tsuas yog siv rau bolting, riveting thiab vuam yam ntxwv qhov chaw rau tsheb, ntim, tsev, yees thiab lwm yam lug siv.Thaum siv los ua cov txheej txheem welded, lub thickness ntawm cov hlau yuav tsum tsis txhob siab tshaj 16 hli.Huab cua-resistant steel rau welded lug muaj kev vuam zoo dua li cov huab cua-resistant structural steel, thiab feem ntau yog siv rau welded structural qhov chaw rau txuas hniav, vaj tse thiab lwm yam lug.
Nco tseg: peb muab kev pabcuam customized, tag nrho cov raj steel yuav ua raws li koj tus qauv tsim los tsim nws.
