Low Temperature Carbon Steel Gate Valve

Low Temperature Carbon Steel Gate Valve

WCB (ASTM A216 Grade WCB), as a classic representative of carbon cast steel for medium temperature, its outstanding performance stems from scientific composition ratio and precise control, and is perfectly adapted to medium and low temperature working conditions ranging from -29 ℃ to +425℃. In terms of composition, the carbon content is strictly controlled at ≤0.30%, which not only ensures excellent basic mechanical properties - tensile strength of 485-655 mpa and yield strength of ≥275MPa, capable of easily withstands the pressure load of medium and low pressure systems, but also avoids the defect of easy cracking of high-carbon materials. Manganese elements and silicon elements work in synergy. Manganese significantly enhances the material's toughness and impact resistance, while silicon optimizes the casting fluidity, making the structure of the castings denser after molding and reducing internal porosity and other defects. Combined with strictly limited phosphorus (≤0.035%) and su…
