LR AH40 shipbuilding steel plates,S355J2 is a low-alloy high-strength steel, which can be treated to meet the requirements of Z-15, Z-25, Z-35 and level I, level II and level III flaw detection.
The extension grades of S355J2 are S355J2, S355J2-Z35 and S355J2 + N-Z35. On the basis of S355J2, S355J2-Z35 increases the requirement of S355J2 steel plate thickness direction performance, namely Z-direction performance. S355J2 + N-Z35 is a heat treatment process which increases Z-direction properties and normalizing rolling (or normalizing).

LR AH40 shipbuilding steel plates,Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor This 20Cr alloy steel still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness,LR AH40 shipbuilding steel plates.
