Stock A514 Gr B steel material in china

Strip steel is mainly used for the manufacture of welded pipes, clamps, washers, spring blades, saw blades, blades and other fields, so the A514 Gr B steel material, strip steel specifications are also relatively standardized. First, the strip width should be within 1300mm, if it is too wide, it will become a steel plate, and the machining is not allowed to be too wide, otherwise it will fail. Second, the strip steel length is not limited, and the strip steel can be coiled together after bending, reducing most of the space.

Sulfur is a very harmful element in A514 Gr B steel material steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of A514 Gr B steel material steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.
