Main causes of subsurface bubble formation in SA573 Grade 70 steel for marine engineering

Semi-endless rolling technology has three advantages: the SA573 Grade 70 steel for marine engineering product's limit thickness and limit width specification range has been significantly expanded. The thinnest thickness of SPHC steel has been expanded from 1.0 mm to 0.78 mm, and the limit specification product width has been expanded from 1100 mm to 1300 mm; The thinnest thickness of Q235B steel has been expanded from 1.2 mm to 1.0 mm, and the width range of the limit specification products has also been further expanded.

Delivery status: Hot-rolled SA573 Grade 70 steel for marine engineering steel In the hot-rolled state or controlled rolling state or heat treatment, the state of delivery, cold-rolled steel to the annealing state of delivery.
