EN 10219 S235JRH Steel Welded Pipe
gnee pipe team
S235JR welded pipe is a kind of alloy structural steel, which is widely used in manufacturing various mechanical equipment and structural parts. Its chemical composition mainly contains elements such as carbon, silicon, manganese, phosphorus and sulfur.
The standard number of 1.0039 steel is "S235JR", where "S" represents structural steel, 235 represents that in the tensile test, its tensile strength reached 235 MPa, and "JR" represents that the steel has good weldability and has Good processability and formability.
S235JR resistance welded pipe has high strength and toughness, excellent wear resistance and corrosion resistance, especially in low temperature environments, its tensile strength remains stable.
In addition, the welding performance of S235JR welded straight seam steel pipe is also very good. Common welding methods include manual arc welding, submerged arc welding and gas shielded welding. During use, you also need to pay attention to low-temperature impact toughness, as well as other factors such as controlling the heating temperature and cooling rate of the steel plate.
