Technical key points for the production of LR D MS marine steel sheet and other marine steels

There are many technical points for the production of LR D MS marine steel sheet and other marine steels. In general, the emphasis is on:

1. Cleaning requirements for marine steel:
For LR D MS marine steel sheet, S should be less than 0.008 and P less than 0.015.

2. LR D MS marine steel sheet and A131 grade low carbon steel can be delivered at hot rolling or controlled rolling stations. A131 marine steel is allowed to be used with normalizing or thermomechanical rolling.

3. LR D MS marine steel sheet and other marine steel quality requirements:

That includes requirements for shape and dimensional accuracy, requirements for ultrasonic flaw detection and performance stability.

At present, most of the rolling conditions of steel mills have passed approval for the production of LR D MS marine steel sheet and other A131 grade marine steel.
