Technical requirements for LR FH36 marine ship building steel plate

The LR FH36 marine ship building steel plate is a high strength shipbuilding steel. It is very strict in technical.. Generally speaking, the technical requirements of LR FH36 shipbuilding steel are mainly embodied in 4 aspects:

1.LR FH36 marine ship building steel plate strength requirements:
High strength can lighten hull weight, reduce welding workload and improve bearing capacity. The use of FH36 high strength shipbuilding steel is also limited by hull rigidity and corrosion resistance.

2.The positioning of the hull is quite complex.
There are many mono curved surfaces or hyperbolic surfaces. Cold, hot bending and straightening are necessary. Therefore, LR FH36 marine ship building steel plate is required to be well adapted to shipbuilding technology, including welding and repair.

3.The strength, plasticity and toughness requirements of LR FH36 marine ship building steel plate are sufficient to compensate for the influence of work hardening and thermal cycling on various processes during construction.

For the most important parts of the bow and hull, such as maximum longitudinal bending stress, bottom and side crack plates, high crack resistance is required.
It requires low brittle transition temperature and sufficient low temperature impact LRorption.

4.The LR FH36 marine ship building steel plate should have good corrosion resistance to seawater.

If the LR FH36 marine ship building steel plate can fully meet the above technical requirements, it will do well after completion of the ship.
