A36 kuv Beam

A36 hlauyog ib hom qauv hlau alloy siv hauv Tebchaws Meskas.The A36 (UNS K02600) tus qauv tau tsim los ntawm ASTM International. Tus qauv tau luam tawm xyoo 1960 thiab tau hloov kho ob peb zaug txij li thaum. Ua ntej xyoo 1960, cov qauv tseem ceeb rau cov qauv hlau hauv North America yog A7 (txog 1967) thiab A9 (rau cov tsev, txog 1940). Nco ntsoov tias SAE / AISI A7 thiab A9 cov cuab yeej hlau tsis zoo ib yam li ASTM A7 thiab A9 cov qauv hlau tsis siv.

Lus Cim: Rau cov duab uas muaj flange thickness ntau tshaj 3 nyob rau hauv (76 mm), 0 85-1.35% manganese cov ntsiab lus thiab 0.15-0.40% silicon ntsiab lus yuav tsum tau.

Raws li nrog rau feem ntau cov hlau, A36 muaj qhov ceev ntawm 7,800 kg / m³({{0}}}.28 lb/cu in). Young's modulus rau A36 steel yog 200 GPa. A36 steel muaj Poisson tus piv ntawm 0.32 thiab shear modulus ntawm 78 GPa (11,300,{10}} psi).

A36 steel nyob rau hauv daim hlau, tuav, thiab cov duab nrog ib tug tuab ntawm tsawg tshaj li 8 nyob rau hauv (203 mm) muaj ib tug tsawg kawg nkaus yield zog ntawm 36, 000 psi (250 MPa) thiab qhov kawg tensile zog ntawm 58, 000–80, 000 psi (400–550 MPa). Cov phaj tuab dua 8 hauv muaj 32, 000 psi (220 MPa) yield zog thiab tib lub zog tensile kawg ntawm 58, 000-80, 000 psi (400-550 MPa) .Qhov hluav taws xob tsis kam ntawm A36 yog 0.142 μΩm ntawm 20 degree . A36 tuav thiab cov duab tuav lawv lub zog kawg txog 650 degree F (343 degree). Tom qab ntawd, qhov tsawg kawg nkaus lub zog poob los ntawm 58, 000 psi (400 MPa): 54, 000 psi (370 MPa) ntawm 700 degree F (371 degree ); 45, 000 psi (310 MPa) ntawm 750 degree F (399 degree); 37, 000 psi (260 MPa) ntawm 800 degree F (427 degree ).
