ASTM A213 / ASME SA213 TP347H STAINLESS STEEL SEAMLESS TUBE BOILER
TUBE
Stainless steel 347H is a stabilized austenitic stainless steel
that contains a higher amount of carbon, compared to standard grade
347. This higher carbon content provides improved high-temperature
strength and resistance to intergranular corrosion.
347H stainless steel tubes are commonly used in applications that
require high-temperature resistance, such as in the manufacturing
of heat exchangers, boilers, and furnace parts. They are also
suitable for use in the petrochemical, chemical, and power
generation industries.
These tubes are available in various sizes, thicknesses, and
lengths to meet specific project requirements. They can be
purchased in seamless or welded forms, depending on the application
and desired characteristics.
The properties of stainless steel 347H tubes include excellent
corrosion resistance, high strength, good weldability, and creep
resistance at elevated temperatures. They have a wide operating
temperature range and can withstand temperatures up to 1000°C
(1832°F) without losing their mechanical properties. Additionally,
stainless steel 347H tubes exhibit resistance to sulfur-bearing
atmospheres, which makes them suitable for use in environments with
sulfur compounds.
