EN S355J2H Structural Rectangular Steel Pipes
gnee pipe team
S355J2H welded steel pipe is a steel pipe manufactured by hot rolling process. Its outer diameter is generally 60-219mm and the wall thickness is 4-20mm. This kind of steel pipe has good mechanical properties, corrosion resistance and low temperature performance, so it has been widely used in petroleum, chemical industry, electric power, construction, shipbuilding and other fields.
S355J2H square tube has excellent mechanical properties. It has high tensile strength and yield strength and can withstand large pressure and bending stress. At the same time, this kind of steel pipe also has good impact energy and toughness, and can withstand strong impact and vibration.
S355J2H straight seam steel pipe has excellent corrosion resistance. Because its surface is covered with an oxide film, this film can effectively resist corrosion by various acids, alkalis, salts and other chemical substances.
