What material is suitable to make the RINA AH32 collision bulkhead steel

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with RINA AH32 collision bulkhead steel ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the RINA AH32 collision bulkhead steel steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

Our company has 80 tons RINA AH32 collision bulkhead steel, 7mm thickness VL Grade A hot rolled sheets in Tianjin stock. Below is the ship steel VL A plates available specification(mm): 7*2850*9850, 7*1770*6000, 7*1770*6000, 7*1950*10600, 7*2300*6000, 7*3000*12000, 7*3030*6900, 7*3180*8600, 7*2950*7350, 7*1950*10500, 7*2350*7700, 7*3030*7900, 7*3100*9300, 7*2920*9900, 7*2850*11400, 7*2400*11000, 7*3030*8000, 7*3080*7650, 7*1910*6000, 7*2950*9400.
