Fake and inferior EN10217-2 P235GH steel pipe often have pitting on the surface. The pitted surface is caused by the serious wear of the rolling groove, which causes the irregular unevenness of the surface of the EN10217-2 P235GH steel pipe.
The surface of the fake EN10217-2 P235GH steel pipe is prone to cracks. The reason is that the billet is adobe, which has many pores. The adobe is subjected to thermal stress during the cooling process, resulting in cracks. After rolling, there will be cracks.
The cross ribs of the fake EN10217-2 P235GH steel pipe are thin and low, and the phenomenon of dissatisfaction often occurs. The reason is that in order to achieve large negative tolerances, the reduction of the first few passes of the finished product is too large, the iron type is too small, and the hole type is not full.
The composition of EN10217-2 P235GH steel pipe is uniform, the tonnage of the cold shear is high, and the end face of the cutting head is smooth and tidy. However, due to the poor material, the end face of the cutting head often has meat loss, that is, it is uneven and has no metallic luster.
