Stelmor® Process, Standard

The Standard Stelmor® Process produces a pseudo-patented microstructure in hot-rolled rod directly in sequence with the rod mill. The rod is cooled at an accelerated rate by forced air blowing, the cooling rate being determined by rod size and conveyor speed. The cooling rate during transformation is faster than that of air patenting, and the Standard Stelmor-processed rods have higher tensile strengths than comparable rods that are air-patented, but less than rods that are lead-patented.
