Khoom Description
Tsawg- alloyA423 Gr.1 welded raj, A423 Gr.1 welded kav, thiabA423 Gr.1 seamless rajnruj me ntsis raws li covASTM A423 / A423M / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / ASTM A423 / A423M / ASTM A423 / ASTM A423 / ASTM A423) thiab A423Mtxheem specification, haum rau seamless thiab hluav taws xob -welded steel hlab.
Cov khoom no yog ib tug tsawg- alloy weathering steel nrog zoo heev corrosion kuj thiab ntev - lub sij hawm durability. Thaum raug ib puag ncig ib puag ncig, cov raj tsim cov txheej txheem tiv thaiv oxide uas muaj txiaj ntsig zoo tiv thaiv kev xeb ntxiv, ua rau lawv zoo tagnrho rau kev tsim choj, kev tsim duab puab, lub tsev facades, kev thauj mus los hauv hiav txwv, thiab kev siv cov kav dej uas yuav tsum tau muaj huab cua tiv thaiv.
A423 Gr.1 raj feem ntau muaj 0.12–0.20% carbon, 0.25–0.50% manganese, 0.25–0.55% tooj liab, thiab 0.30–1.00% chromium, sib txuas lub zog thiab huab cua tsis kam.
Cov raj muaj lub zog tawm los txog li 37 ksi (kwv yees li 255 MPa), lub zog tensile mus txog 60 ksi (kwv yees li 415 MPa), elongation tsis pub tsawg tshaj 25% ntawm 2- nti lossis 50 hli cov qauv, thiab Brinell hardness tsis tshaj 1. Cov khoom no xyuas kom meej tias cov hlab ntsha tuaj yeem tiv taus kev nthuav dav, hlaws, lossis tsim cov haujlwm yam tsis muaj kev tawg lossis tsis xws luag thaum tswj kev ua haujlwm zoo tshaj plaws hauv kev siv mus ntev.
ASTM A423 Gr.1 raj yog tshwj xeeb tshaj yog haum rau kev lag luam ib puag ncig uas muaj kev tiv thaiv corrosion siab, xws li qab zib mills thiab ntau yam ua haujlwm, thiab kuj tau siv dav hauv kev siv vaj tsev thiab duab puab. Thaum yuav khoom,
nws pom zoo kom thov covMill Test Certificate (MTC)thiab daim ntawv pov thawj ua raws li ASTM cov qauv los xyuas kom meej tias cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab ntawm cov raj ua tau raws li qhov yuav tsum tau ua.
