    平陽q345b方管產品詳情

    q345b方管

      說明用途

      q345b方管是一種空心方形的截面輕型薄壁鋼管,也稱為鋼制冷彎型材。它是以q345b熱軋或冷軋帶鋼或卷板為母材經冷彎曲加工成型后再經高頻焊接制成的方形截面形狀尺寸的型鋼。熱軋特厚壁方管除壁厚增厚外情況,其角部尺寸和邊部平直度均達到甚至超過電阻焊冷成型方管的水平.

      q345b方管用途

      q345b方管一般用于建筑,機械制造,鋼鐵建設項目, 造船,太陽能發電支架,鋼結構工程,電力工程,電廠,農業和化學機械,玻璃幕墻,汽車底盤,機場等。

      q345b方管無縫和焊縫之分

      q345b無縫方管是將q345b無縫圓管擠壓成型而成。

      q345b方管塑性

      塑性是指金屬材料在載荷作用下,產生塑性變形(永久變形)而不破壞的能力。

      q345b方管硬度

      硬度是衡量金屬材料軟硬程度的指針。生產中測定硬度方法最常用的是壓入硬度法,它是用一定幾何形狀的壓頭在一定載荷下壓入被測試的金屬材料表面,根據被壓入程度來測定其硬度值。

      常用的方法有布氏硬度(HB)、洛氏硬度(HRA、HRB、HRC)和維氏硬度(HV)等方法。
