Weathering Hlau Khoom Description
Q420qDNH weathering steel yog carbon steel structural steel nrog weathering kev ua tau zoo, uas yog weathering steel rau txuas hniav. Q420qDNH corten weathering steel tus qauv: siv GB / T714 tus qauv.
Qhov zoo ntawm Q420qDNH choj weathering steel:
1. Qhov kub thiab txias tsis zoo, uas tuaj yeem ua tau raws li qhov xav tau ntawm kev cuam tshuam lub zog siab tshaj 150J hauv -40 degree ib puag ncig.
2. Nws muaj qhov ntsuas huab cua tsis zoo thiab tuaj yeem tiv thaiv corrosion los ntawm huab cua, dej hiav txwv, thiab lwm yam., txuas ntxiv nws lub neej kev pab cuam.
4. Tsawg carbon tsim kom ntseeg tau zoo vuam kev ua tau zoo. Tsis tas yuav tsum tau preheat thaum lub sij hawm ua thiab tuaj yeem ncaj qha welded, uas yooj yim rau cov neeg siv khoom nruab thiab tsim tom qab.
5. Lub sijhawm xa khoom luv luv, uas tuaj yeem txo cov nqi tsim khoom rau cov neeg siv khoom.
Q420qDNH corten daim ntawv muaj lub zog siab thiab tsis tshua muaj kev cuam tshuam qhov kub thiab txias, uas ua lub luag haujlwm tiv thaiv huab cua-resistant cov qauv. Thaum ua kom muaj kev ruaj ntseg ntawm cov qauv, nws kuj zoo heev rau kev pab cuam lub neej thiab kuj txo tus nqi ntawm kev saib xyuas tom qab.
Q420qDNH weathering steel general specifications thickness: 8mm{2}}mm, dav: 1600mm-3900mm, ntev: 6000mm-14000mm. GNEE kuj tseem tuaj yeem ua yav tom ntej dov raws li koj xav tau.
Q420qDNH corten weathering steel muaj kev qaug zog zoo, qee qhov kub tsis tshua muaj zog thiab atmospheric corrosion kuj. Nws yog dav siv nyob rau hauv steel rau lub tsev railways los yog hla hiav txwv choj.
