Introduction
ASTM A213 /
A213M covers seamless ferritic and austenitic alloy steel tubes intended for
boilers, superheaters, and heat exchangers. These tubes are designed for
high-temperature service and provide excellent strength, corrosion resistance,
and long-term durability under pressure.
ASTM A213
tubes are widely used in power plants, refineries, and industrial heating
systems where performance at elevated temperatures and resistance to oxidation
are critical.
