ballistic steel EN1522 FB5 class vs a36 grade

The bridge steel plate ballistic steel EN1522 FB5 class produced by BBN company has pure steel, flat and smooth plate surface, small difference between plates, -40 ℃ impact value and aging impact value are stable, and the margin is large. Bridge steel plates can be controlled by rolling, cooling, normalizing, and tempering organize production with different production processes. This bridge steel ballistic steel EN1522 FB5 class is widely used in the manufacture of large railway bridges and highway bridges.

The company has ballistic steel EN1522 FB5 class advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience ballistic steel EN1522 FB5 class, we have accumulated a large number of customers at home and abroad, and won unanimous praise.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This ballistic steel EN1522 FB5 class rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for ballistic steel EN1522 FB5 class and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
