ASTM A182 F304 Forged Swage MSS SP-95
ASTM A182 F304 specification covers forged or rolled alloy and stainless steel pipe flanges， forged fittings， and valves and parts for high-temperature service. After hot working， forgings shall be cooled to a specific temperature prior to heat treatment， which shall be performed in accordance with certain requirements such as heat treatment type， austenitizing/solution temperature， cooling media， and quenching. The materials shall conform to the required chemical composition for carbon， manganese， phosphorus， silicon， nickel， chromium， molybdenum， columbium， titanium. The material shall conform to the requirements as to mechanical properties for the grade ordered such as tensile strength， yield strength， elongation， Brinell hardness. All H grades and grade F 63 shall be tested for average grain size.
ASTM A182 F304 is a standard specification for forged or rolled alloy and stainless steel pipe flanges， forged fittings， and valves. A forged swage is a type of fitting used to connect two pipes of different sizes. MSS SP-95 is a standard specification for swage nipples and bull plugs.
Therefore， an ASTM A182 F304 Forged Swage MSS SP-95 refers to a swage fitting made of stainless steel grade F304 that meets the specifications outlined in MSS SP-95. This type of fitting is commonly used in piping systems to reduce or increase the size of the pipe diameter.
