不过,方管的分类有很多,有按材质、生产工艺、生产标准为依据进行区分,也有按照形状进行区分。总之,林林总总的多达数千种,分类如下:
However, there are many classifications of square tubes, including differentiation based on material, production process, and production standards, as well as differentiation based on shape. In short, there are a plethora of thousands of species, classified as follows:
方管按材质分类
Classification of square tubes by material
普碳钢方管、低合金方管。普碳钢分为:Q195、Q215、Q235、SS400、20#钢、45#钢等;低合金钢分为Q345、16Mn、Q390、ST52-3等。
Plain carbon steel square tubes, low alloy square tubes. Plain carbon steel is divided into Q195, Q215, Q235, SS400, 20 # steel, 45 # steel, etc; Low alloy steel is divided into Q345, 16Mn, Q390, ST52-3, etc.
方管按生产标准分类
Square tubes are classified according to production standards
