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 A572 Gr 50 high strength steel is highly elastic, reused in mechanical equipment, memoryless, deformation free, and antistatic.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the A572 Gr 50 high strength steel metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between A572 Gr 50 high strength steel strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
We supply 5800 tons A53 Gr B ERW pipes to Qatar for Qatar Integrated Railway Project - Green Line. This is the first Metro Line in Qatar, and it is located in Doha. We got the order by tender, launched by the Qatar Railways Company for designing, construction and completion of Green Line Project. Before putting order, a delegation from the A572 Gr 50 high strength steel project side visited us and several other famous steel pipe mills in China for 15 days. Finally, we were chosen and finished the task exceeding their expectations.
