Introduction
ASTM A250 / A250M covers
electric-resistance welded (ERW) ferritic alloy steel tubes intended for
boilers, superheaters, and heat exchangers. These tubes are designed for
high-temperature service and offer good mechanical strength, heat resistance,
and durability under pressure conditions.
ASTM A250 alloy steel tubes
are widely used in thermal power plants and industrial heating systems where
reliable performance at elevated temperatures is essential.
