A572 Gr 60 ms steel coil surface cracks refer to the linear cracks on the surface of A572 Gr 60 ms steel coil, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: A572 Gr 60 ms steel coil surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.
In 2019, the output of pig iron in the world was 1.265 billion tons, with China accounting for 64%; the overseas output accounted for 36% (460 million tons), ranking 86.982 million tons of EU 28 countries, 74.907 million tons of Japan, 74.099 million tons of India, 73.264 million tons of CIS, and A572 Gr 60 ms steel coil 47.521 million tons of South Korea.
The carbon content of A572 Gr 60 ms steel coil carbon structural steel is about 0.05% - 0.70%, some of which can be as high as 0.90%. Carbon structural steel can be divided into ordinary carbon structural steel and high-quality carbon structural steel. Carbon structural steel is mainly used in railway, bridge and all kinds of construction projects. Carbon structural steel A572 Gr 60 ms steel coil can be used to manufacture all kinds of metal components that bear static load and unimportant mechanical parts and general weldments that do not need heat treatment.
