High-Temperature Stop Valve for Industrial Use

WC6 (ASTM A217 WC6), as a 1¼Cr - ½Mo alloy cast steel, with its outstanding material stability and long-term reliability, makes it a "safety barrier" for the long-term operation of high-temperature equipment, especially suitable for long-term working conditions up to 593℃ (1100℉). From a microstructure perspective, after WC6 undergoes an optimized heat treatment process, it forms a uniform pearlite + ferrite structure, with refined and evenly distributed grains. When exposed to high-temperature environments for a long time, it is less likely to experience problems such as coarse grains and carbide precipitation and aggregation, ensuring that the material's mechanical properties (tensile strength, yield strength) decline at a rate of less than 10% during its service life. Avoid equipment failure caused by performance degradation. In terms of corrosion stability, the oxide film formed by 1.0-1.5% chromium in WC6 has excellent adhesion and density. Even in high-temperature steam or sligh…
