What is SA573 Grade 70 structural steel dimension equivalent ASTM steel

API 5L Gr.B steel plate is one mainly of Steel for large diameter pipes,API-Gr.B steel is manufactured using premium grade of raw material. These products SA573 Grade 70 structural steel dimension are used to flow steam, water, oil and various petrochemicals substance in various petrochemical and chemical industries. These Steel Seamless Pipes are widely appreciated for high performance and less maintenance.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized SA573 Grade 70 structural steel dimension are higher than that of annealed SA573 Grade 70 structural steel dimension, but the elimination of internal stress is not as good as annealing. The normalizing operation of SA573 Grade 70 structural steel dimension is simple, the cost is low, the productivity is high, and it is widely used in actual production.
