What are the quality requirements of SMA490BW hot rolled structural steel grade

The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality SMA490BW hot rolled structural steel grade products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.

The main difference between SMA490BW hot rolled structural steel grade, 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.

SMA490BW hot rolled structural steel grade product plate specification range:
Thickness 3-150mm
Width 1500-4020mm
Length 4000mm-17000mm
Heat treatment: annealing, or normalizing and tempering
