“ASTM A182 GR F11 CL2 valve body, TRIM CN 5, standard bore – What material are the valve body and valve stem of this American standard valve made of? What does CL2 mean, and under what standards can it be found? What material is CN5 made of, and under what standards can this be found? First, thank you all, guys.
The material of the ASTM A182 GR F11 CL2 valve body is alloy steel (grade F11), and “CL2” indicates the second category of heat treatment conditions. The specific meaning can be looked up by referring to the standards of the American Society for Testing and Materials (ASTM). The material of the TRIM CN5 valve core is hard-faced or nickel-containing stainless steel, and this type of valve core offers better corrosion resistance. For specific material correspondences, you can refer to the manufacturer’s standards or API (American Petroleum Institute) standards. .
Does this seem to be a special-material valve? Similar to those used for high-pressure steam lines?
The meaning of ASTM A182 GR F11 CL2 can be found in the standard. See attached figure for CN5.
