q345b steel tube thickness

A brief introduction to Chinese GB standard - IMRI Steel

Mar 17, 2020 · Q345 steel, with charicteristics of 7.85 g/cm3 material density, and 470-630 Mpa tensile strength, is a Chinese GB standard low alloy high strength structural steel. Q is the first letter of Chinese Pinyin:qu fu dian, which means Yield Point, 345 is the minimum value of yield strength for steel thickness less than 16mm. ASTM A53, ASTM A120 Hot Dip Galvanized Steel Pipe, 1/2 to Our pre-galvanized welded steel pipe is made of exceptional quality steel materials, and the offered steel type includes GR.B, Q235, q345b, and q195. The Q235 steel function good elongation, tensile strength, persistence, and castability, so bonded pipes made
