SA573 Grade 70 steel for marine engineering steel plates manufacturers and suppliers

High toughness and low brittleness transition temperature: with the increase of the working pressure of the SA573 Grade 70 steel for marine engineering gas pipeline, the pipe diameter becomes larger, and the pipeline fracture accidents often occur. Toughness is the key factor affecting pipeline fracture. In order to ensure SA573 Grade 70 steel for marine engineering pipeline safety, toughness and strength must be improved at the same time.

The outer diameter of the hot-rolled seamless pipe is generally larger than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm. The size accuracy of the cold-rolled seamless pipe is higher than that of the hot-rolled seamless pipe, SA573 Grade 70 steel for marine engineering.
