A573 grade 70 structural steel carbon plate with different thickness

The main difference between a573 grade 70 structural steel carbon plate, 45# steel plate and boiler steel plate is the difference of carbon content and impact toughness. 45# steel is a high-quality carbon structural steel, which is expressed by the number of ten thousand percent of the average carbon content. The 45# steel represents the high-quality carbon structural steel with 0.45 percent carbon content. The high-quality carbon structural steel contains less harmful impurity elements (S, P) and non-metallic inclusions, and has excellent plasticity, toughness and processing technology.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the a573 grade 70 structural steel carbon plate steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
