Q235B carbon steel tube is a widely used steel material and belongs to carbon structural steel. "Q235B" has a specific meaning. "Q" represents the yield point of steel, "235" means the yield point value is 235MPa, and "B" represents the quality grade. This type of steel pipe has a low carbon content, usually not exceeding 0.2%, and also contains small amounts of silicon, manganese and other elements. Due to its low carbon content, it has good plasticity and toughness and is easy to process and shape. At the same time, as structural steel, Q235B carbon steel tube can withstand certain loads, provide stable support for various structures, and play an important role in many fields.
