The raw material S355JR used by Socket Welding Flange is a low alloy high strength structural steel conforming to European standard en10025. S355jr steel in China is a low alloy high strength structural steel with hardness of 70-80b and yield strength of 300-400mpa. The raw material of EN S355JR SW Flanges is low alloy high strength structural steel conforming to European standard en10025. S355jr steel in China is a low alloy high strength structural steel with hardness of 70-80b and yield strength of 300-400mpa.
S355jr chemical composition of raw materials of S355JR SW Flange: C: ≤ 0.22; Si:≤0.55; Mn:≤1.60; P:≤0.025; S:≤0.025
S355jr is equivalent to Q345B in China, so it is normal for people to replaceEN S355JR SW Flanges with Q345B SW flanges in enquires and orders of S355JR Socket Welding Flange. We hope that all purchasers will know this. In the actual flange production, this is not only the case with S355JR SW flanges. Many of them have different labels due to different national social and cultural customs, but they are essentially the same. In this case, it is only necessary to compare the mechanical properties and chemical materials of EN S355JR SW Flanges. The Socket Welding Flange Flanges we produce provide the corresponding 3.1B Certificate in strict accordance with the standard, and can also be verified by doing various experiments, If you have any questions about S355JR Socket Welding Flange Flanges, please feel free to contact: china@hkflanges.cn.
