Why should weather resistant Q355GNH steel be cut and heat treated

We specialize in the production of steel pipe, including hot-rolled seamless steel pipe, ERW steel pipe, LSAW steel pipe, spiral welded pipe, stainless steel pipe, RHS / SHS, weather resistant Q355GNH steel. The company's annual sales volume is 75000 tons, more than doubling in the past five years, mainly used in machinery, pipeline, heating, oil drilling, chemical industry, agricultural irrigation, urban construction and other industries. So far, our pipeline service customers come from more than 40 countries.

Ultrasonic flaw detection emits ultrasonic waves to the weather resistant Q355GNH steel steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the weather resistant Q355GNH steel steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.

Facing the future, BBN Steel is willing to work with BHP Billiton to promote low-carbon metallurgy and recycling technology innovation and R&D deployment. Green raw materials are used to make green steel and contribute to the realization of green and low-carbon development of the steel industry chain and the building of a community with a shared future for mankind.

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 weather resistant Q355GNH steel is highly elastic, reused in mechanical equipment, memoryless, deformation free, and antistatic.
