Abstract ALLEGHENY ALMAR-362 is an age-hardenable martensitic stainless steel recommended for applications requiring high strength and good corrosion resistance, such as aircraft and missile structures, hydraulic and pneumatic equipment components, and in the chemical processing industry. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as fracture toughness. It also includes information on corrosion resistance as well as casting, forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-234.

The 2010 Edition of the American Society of Mechanical Engineers (ASME) B31.3 Procecess Piping Code [1] includes a new chapter: Chapter X High Purity Piping. Chapter X covers industries listed in the scope of ASME B31.3 which use methods of fabrication, examination, inspection and testing different than other industries covered by the Code. Industries which have a need for cleanness and cleanability on a more demanding level, such as the semiconductor industry, which uses Semiconductor Equipment and Materials International (SEMI) Standards [2–4], and the pharmaceutical and bioprocessing industries, which use the ASME Bioprocessing Equipment (BPE) Standard [5], also reference ASME B31.3 for safety requirements. ASME B31.3 now addresses issues common to the semiconductor and biopharmaceutical industries. The new High Purity Fluid Service defined in Chapter X permits weld coupon examination in lieu of the 5% radiography required in Normal Fluid Service when orbital welding is used in fabrication. Industries that may not otherwise be considered as high purity, such as refineries, the chemical processing industry [6–7], solar panel fabrication and nuclear or petrochemical applications that could use tubing rather than pipe, may benefit from the fabrication technology introduced in Chapter X while meeting the safety requirements of the Code.
