Q345GNHLJ Weathering resistant steel round bar, Q345GNHLJ steel bar CR

Q345GNHLJ Weathering resistant steel round bar exhibit a good resistance to corrosion than ordinary steel, it has smallest alloy elements not like stainless steel and its price is more cheaper than stainless. Q345GNHLJ steel begins to rust in the same way as ordinary steel. But soon the alloying elements in it cause a protective surface layer of fine-textured rust to form, thereby suppressing corrosion rate.

Q345GNHLJ steel bar has added phosphorous which makes the material best suited for gas flue applications and for aesthetic facias . Q345GNHLJ steel round bar is used for various types of welded, bolted and riveted constructions e.g. steel frame structures, bridges, vehicles and equipment constructions .
