China Pressure Seal Gate Valve

What is the temperature applicable to WC9 and WC6 castings respectively?

/in /by

The suitable working temperature of WC6 is -29 ~ 540 °C, and the suitable working temperature of WC9 is -29 ~ 570 °C.

Both specifications are chrome-molybdenum steel, and the mechanical properties of the two are basically the same, with the same tensile strength, yield strength and elongation at room temperature.
The Cr-Mo high temperature cast steel used for the valve mainly adopts WC6, WC9 and C5 (ZG1Cr5Mo) in the ASTM A217 standard, and the corresponding rolled materials are F11, F22 and F5 in ASTM A182, respectively.
Low chromium grade chromium-molybdenum steel Low chromium grade chromium-molybdenum steels are available in WC6, WC9, F11 and F22. The suitable working medium is water, steam and hydrogen. It is not suitable for sulfur-containing oils. WC6 and F11 are suitable for -29-540 °C, and WC9 and F22 are suitable for -29-570 °C.
Chromium five molybdenum high temperature steel Chromium five molybdenum high temperature steel has C5 (ZG1Cr5Mo) and F5, and its applicable working medium is water, steam, hydrogen and sulfur oil. C5 (ZG1Cr5Mo), if used for water vapor, has a maximum operating temperature of 600 °C. When used in working media such as sulfur-containing oils, the maximum operating temperature is 550 °C. Therefore, the operating temperature of C5 (ZG1Cr5Mo) is specified to be ≤550 °C.
