Tungsten carbide remains the gold standard for gate and seat hardfacing. Applied via high-velocity oxygen fuel (HVOF), it achieves bond strengths exceeding 10,000 psi. The coating thickness of 0.010–0.015 inches resists erosion from high-velocity fluids. Microhardness reaches 1,200–1,600 HV, far surpassing stellite. In H2S environments, carbide prevents sulfide stress cracking. Regula... https://globalsealstech.com/
