ASTM A671 yog dab tsi?
ASTM A671 Tube yogua los ntawm cov khoom siv roj carbon tsawg uas tsim nyog rau siab - cov ntawv thov siab ntawm qhov kub qis. Cov kav dej tuaj yeem siv tau rau hauv chav tsev kub, tab sis tsis yog saum toj no rau kev ua haujlwm.
Dab tsi yog qhov txawv ntawm ASTM A671 thiab ASTM A672?
A671 tsom mus rau qhov siab - lub zog yuav tsum muaj ntawm cov hlab ntsha siab thiab cov khoom siv, thaum A672 tsom rau kev ua tau zoo thiab ua haujlwm ntev ntawm kev thauj mus los.
A671 GR CC65 khoom yog dab tsi?
ASTM A671 Qib CC65Electric Fusion Welded Yeeb Nkabyog tsim los nrog lub zog tawm los ntawm 240N / mm2 thiab lub zog tensile ntawm 450-585N / mm2. Cov kav dej no muaj lub zog tensile zoo sib xws thaum lub vuam taw tes tau ntsib. Carbon Steel ASTM A671 Gr CC65 EFW steel yeeb nkab muaj carbon raws li nws cov ntsiab lus tseem ceeb.
ASTM A671 GR CC60 khoom yog dab tsi?
ASTM A671 CC60 npog cov qauv kev qhia tshwj xeeb rau hluav taws xob welded fusion steel kav. ASTM A671 Gr CC60 Chav Kawm 22 yogua los ntawm cov khoom tseem ceeb ntawm carbon, silicon, phosphorous, thiab sulfur. Cov kav dej no yog tsim los nrog zoo heev ductility thiab weldability. Tsis tas li ntawd, lawv muaj qhov zoo toughness thiab lub zog.
Dab tsi yog qhov muaj pes tsawg leeg ntawm astm A671?
Cov khoom siv yeeb nkab a671 suav nrog0.24% carbon, 0.13% mus rau 0.45% Silicon, 0.79% rau 1.30% Manganese. Cov pa roj carbon no-raws li stainless- hlau alloy kuj muaj cov lej ntawm lwm cov minerals. Piv txwv li, 0.035% ntawm phosphorus thiab Sulfur tuaj yeem pom hauv cov hlau.
