S355J2 steel plate yield strength Rp0.2≥265mpa, tensile strength RM: 450-680mpa, elongation a≥12%, impact energy Kv2≥27J, tensile area shrinkage Z≥35% in thickness direction. A131 AH40 offshore platform steel, S355J2 steel plate has good internal quality, high density and stable performance.Meaning of S355J2-Z35: J2 requires negative 20 degree impact, and Z35 is the Z-direction performance of S355J2 steel plate.The meaning of S355J2 + N-Z35: J2 requires negative 20 degree impact, N means normalizing rolling rather than normalizing. Z35 is the Z-direction performance of S355J2 steel plate, A131 AH40 offshore platform steel.
NM series wear-resistant steel plates have uniform hardness, avoid the local fracture phenomenon caused by uneven hardness. Compared with ordinary steel plate, NM360 steel plate has wear resistance of not less than twice, NM400 steel plate has wear resistance of not less than 2.5 times, and NM550 steel plate has wear resistance of not less than 4 times. The wear-resistant steel plate combines the characteristics of high strength, high hardness, weldability and easy bending.
