ASTM A182 flanges can be used in high temperature environments. The specification also wraps the heat treatment, in addition to the chemical and mechanical properties required for 304 stainless steel flanges. The mechanical properties covered by the specification include tensile strength, yield strength, and elongation and Brinell hardness values for stainless steel 304 flanges. In addition to grade 304 being a versatile alloy, many manufacturers prefer to use this alloy to make ASTM A182 Grade F304 WNRF flanges because it reduces the cost of applications compared to other alloy grades such as 316. SS 304 blind flanges are often used to prevent the flow of media or to seal valves across piping systems if they are to be repaired, modified or permanently Closure.
