Marine steel is widely used in all kinds of ships and offshore platforms, but it also puts forward higher and higher requirements for marine steel. In general, the demand share of LR DH40 deck house steel high-strength marine steel continues to increase. In terms of strength requirements, with the change of ship's large-scale, safety and coating specifications, the general trend is that the consumption of ordinary strength grade A marine steel plate is gradually reduced, and the consumption of high-strength marine steel plates is increased.
LR DH40 deck house steel product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering
The cold working performance of LR DH40 deck house steel and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of LR DH40 deck house steel and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.
BBN can provide hot-rolled and cold-rolled steel plates, as well as special processing and cutting (any size and shape) drilling, welding, milling, LR DH40 deck house steel processing and steel structures according to drawings. Welcome new and old customers to purchase steel plate from BBN.
