Q345B Alloy Pipe

Q345B alloy tube is a kind of steel pipe material. Q represents the yield of this material, the back of the 345 is the yield value of this material, in 34 or so, and with the increase in the thickness of the material and the yield value decreases.

Q345B alloy pipe is divided into seamless pipe for structure and high pressure heat-resistant alloy pipe. The main difference between the production standard of alloy pipe and its industry, the annealing and tempering of alloy pipe to change its mechanical properties. To achieve the required processing conditions. Its performance than the general seamless steel pipe multi-variable utilisation value is higher, the chemical composition of Q345B alloy pipe contains more Cr, high temperature, low temperature, corrosion resistance. Plain carbon seamless pipe does not contain alloy composition or alloy composition is very little, alloy pipe in the petroleum, aerospace, chemical, electric power, boiler, military and other industries are more widely used because of the mechanical properties of the Q345B alloy pipe multi-variable good adjustment.
