15crmo Alloy steel pipe: steels, pearlite, heat-resisting steels with high thermal strength (ΔB≥440MPA) and antioxidant resistance at elevated temperatures, and have certain hydrogen corrosion resistance. Because of the high content of CR, C and other alloying elements in steel, the hardening tendency of steels is obvious and the weldability is poor.
Low-quality 15crmo alloy steel pipe prone to folding. Folding is a variety of lines formed on the surface of a 15crmo alloy steel tube, which often runs through the longitudinal of the product. Folding products will crack after bending, the strength of 15crmo alloy steel pipe greatly reduced.
The appearance of inferior 15crmo alloy steel tube often has pock phenomenon. The pock is due to the irregularity of the surface irregularities of the 15crmo alloy steel pipe caused by the abrasion of the grooves.
Poor quality 15crmo alloy steel pipe surface prone to scab and crack.
High quality 15crmo alloy steel pipe composition uniformity, cold shearing machine tonnage high, cutting head face smooth and tidy, and poor quality material because of poor material, cutting the end of the face will often have the phenomenon of meat, that is uneven, and no metallic luster.
