ASTM A 709 Gr.50W Huab cua-resistant steel ntawv
ASTM A709 Gr.50W Weathering Steel Phaj yog ib qho tsis tshua muaj hlau, siab zog steel phaj tsim raws li ASTM (American Society for Testing and Materials) Standard A709. Qhov twg "50" qhia qhov tsawg kawg nkaus tensile lub zog ntawm 50 ksi (kwv yees li 345 MPa) thiab "W" qhia tias cov hlau muaj huab cua zoo.
Cov yam ntxwv ntawm ASTM A 709 Gr.50W weathered steel phaj
Cov huab cua zoo: A709 Gr.50W Weather Corten Steel tuaj yeem tsim cov chaw tuab neeg, tshwj xeeb yog haum rau kev tsim kho hauv tsev marine thiab cov xwm txheej hnyav.
Lub zog siab thiab cov ntsiab lus tsis tshua muaj alloy: A709 Gr.50W corten steel qauv, raws li hom tsis tshua muaj alloy high-strength structural steel phaj, muaj lub zog siab thiab tawv, uas tuaj yeem ua tau raws li cov kev cai ntawm cov choj, cov tsev thiab lwm yam kev tsim vaj tsev ntawm lub zog. , toughness thiab durability ntawm cov khoom.
Txhim kho qhov sib piv ntawm alloying ntsiab: A709 Gr.50W weathering steel Los ntawm kev tswj cov ntsiab lus ntawm carbon, sulphur, phosphorus thiab lwm yam teeb meem, nws txo qhov rhiab heev ntawm weld tawg ntawm steel phaj thiab txhim kho qhov zoo ntawm cov pob qij txha welded.
A709 Gr.50W steel phaj muaj lub zog siab thiab toughness, tib lub sijhawm, nws kuj muaj kev qaug zog zoo thiab qee qhov kub tsis tshua muaj siab toughness.A709 Gr.50W corten steel cov khoom tuaj yeem muab kev pab lub neej ntev thiab zoo heev corrosion kuj, yog ib qho ntawm cov cov ntaub ntawv tseem ceeb hauv structural engineering.
ASTM A 709 Gr.50W corten weathering steel feem ntau yog siv rau hauv cov txuas hniav, cov tsev thiab lwm yam kev tsim vaj tsev, tshwj xeeb tshaj yog nyob rau hauv marine ib puag ncig thiab hnyav huab cua hauv cov txheej txheem engineering muaj ntau yam kev siv.
