1, advantages of Q345B cold drawn square tube:
Q345B cold drawn square pipe is compared with solid stainless steel plates such as Yuangang.When the bending strength and torsion and compression strength are the same, the net weight of Q345C seamless steel pipe is relatively light.The knowledge of Q345B square pipe production and processing advantage is a kind of economic development cross-section stainless steel Plates are generally used to produce parts and mechanical parts, such as crude oil drilling tools, drive shafts, bicycle frames and steel pipe scaffolds used in construction projects.Using seamless steel tubes to produce ring parts, Q345B square tube-Q345B seamless square tube-Q345B square steel tube-Q345B cold drawn square tube-Shandong Dingyu Metal Materials Co., Ltd. can increase the utilization rate of raw materials and simplify the production and manufacturing process.It saves raw materials and comprehensive man-hours for production and processing, such as roller bearing rings, hydraulic jack sleeves, etc. At this stage, seamless steel pipes are commonly used for manufacturing.
2, defects of Q345C seamless steel tube Q345B cold drawn square tube:
Q345B cold-drawn square tube is still a raw material that a variety of strategic weapons cannot lack.A tubis fertilibus et cylindris ferri suntAccording to the cross-sectional area, seamless steel pipes can be divided into round steel pipes and special-shaped steels. Because under the same diameter standard, the Q345B square tube has a larger circle ar
