ASTM A105 ist der standard specification für carbon steel forgings für piping applications—flanges, fittings, valves, und pressure-containing teile für ambient und hoch-temperature service auf zu 425°C (800°F). Forgings sind produced von killed steel mit 0.35% max carbon und sind supplied in der normalized oder normalized-und-tempered condition. Jede forging ist hydrostatically tested per ASME B16.5/B16.11 requirements. A105 ist compatible mit A53, A106, und API 5L piping systems, making es der default flange und fitting material für petrochemical, power generation, und process piping.

Frequently Asked Questions
Können A105 sein used für niedrig-temperature service?
Norm A105 ist nicht impact-tested und ist limited zu -29°C (-20°F) minimum design metal temperature per ASME B31.3. Für unter temperatures, specify A350 LF2 (impact-tested carbon steel forgings für -46°C service) oder A182 F304/F316 (stainless steel forgings für cryogenic service).
