The tensile strength of seamless steel pipe is more than 8-10 times of that of ordinary steel, and its elastic modulus is better than that of steel, with excellent creep resistance, corrosion resistance and seismic resistance; the mechanical performance of seamless steel pipe is excellent, easy to machine, etc.; the seamless steel pipe A514 Gr Q structural steel material is highly elastic, reused in mechanical equipment, memoryless, deformation free, and antistatic.
Q550B steel is a low-alloy high-strength structural steel grade. Steel Q550A is not required for impact toughness test; Q550B is for impact toughness test at room temperature (20℃); Q550C is for 0℃ impact toughness test; Q550D is for impact toughness test at -20℃; Q550E grade is for impact toughness test Make impact toughness test at -40℃. The impact toughness test uses Charpy V-notch specimens. The impact toughness index is Akv.
BBN offers computer automated cutting of steel plate up to 12″ thick. We maintain a large library of standard shapes / patterns with the capability to electronically download customer's CAD files for use in cutting custom steel shapes / A514 Gr Q structural steel material patterns. For tighter tolerance requirements we offer Plasma cutting.
