2 - 80 Mm SAE1518(Q345B) Precision Hollow Bar Seamless Steel Pipe Seamless Pipe Tube

SAE1518(Q345B) Precision Seamless Steel Pipe Seamless Pipe usded as Nitrogen Drilling Pipe chemical composition and techanical property:

stock sizes:

outer diameters: 26mm -720mm

wall thickness: 6mm-80mm

length : 5000mm-13000mm

other sizes need new production.

Alloy elements in Q345B precision steel pipe have great influence on low temperature tempering brittleness. Chromium and manganese promote the segregation of impurity elements such as phosphorus at austenite grain boundaries, thus promoting low temperature tempering brittleness, tungsten and vanadium basically have no effect, molybdenum reduces the ductile-brittleness transition temperature of low temperature tempering precision tube, but it is not enough to inhibit low temperature tempering brittleness. Silicon can delay the precipitation of cementite during tempering and increase its formation temperature, so it can increase the temperature at which the brittleness of precision tube occurs at low temperature.

Q345B precision steel tube is a seamless steel tube with high precision and high brightness produced by cold drawing or cold rolling process. Its inner and outer diameter size can be less than 0.2mm, while ensuring the same bending and torsional strength, light weight, so it is widely used in manufacturing precision machinery parts and engineering structures.

Thick wall steel pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction. For liquid transportation: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural use: for piling pipes, Bridges; Pipe for wharf, road, building structure, etc.
