s355jr s355j0 s355j2 Normalized Steel Bar
S355jr steel is one kind of low alloy carbon steel grade with minimum yield strength 355MPa. S355jr steel is widely used in structural engineering and construction industries. Based on different impact properties requirements, s355jr steel grade is also divided to s355jr, s355j0 and s355j2. Except Hot Rolled Steel Round Bar, we produce S355JR Cold Drawn Steel Round Bar, Cold Drawn Square Steel Bar, cold drawn hexagonal steel and Flat Steel Bar.
S355jr steel bar has various applications such as components as freight cars, transmission towers, dump trucks, cranes, trailers, bull dozers, excavators, forestry machines, railway wagons etc.
s355jr+N, S355J0+N, S355J2+N means S355JR, S355J0 or S355J2 steel grade Normalized Steel bars. To reach the basic steel mechanical properties of these materials or higher strength, the bars are required to be normalized.
