The ferritic structure of
SEA-CURE®
stainless steel provides a
high strength/low work
hardening material with good
ductility. These properties
allow high design stress
limits with good fabrication
characteristics. Because of
the nickel addition, SEA-CURE® has a lower ductile to brittle transition
temperature than similar
ferritic steels without
nickel additions.
Advantages of High Performance
Stainless Steel
Full cold working of the weld using tooling on both OD and ID surfaces prior to annealing ensure optimum homogenization
Cost-effective in high chloride applications and where the potential for microbiological influenced corrosion exists
Special anneal & water quench dissolves secondary phases present in the strip material and prevents the re-formation of them
Chemical pickle and passivation removes surface oxides and protects against chromium depletion, by creating a chromium rich surface layer.
20 years of commercial history with an outstanding performance record, accepted by both Section III and Section VIII of the ASME Boiler Code
Special anneal & water quench
dissolution of secondary phases that may
be present in the strip material and to
prevent the re-formation of them
Ensured by proprietary chemistry for optimum corrosion resistance, developed by Plymouth Tube Company
Technical and customer support for tube
processing based upon 25+ years of

SEA-CURE®
stainless is a patented alloy
made exclusively by Plymouth
Tube Company. Its composition is
given in Table 1. Plymouth manufactures tubing in sizes from 1/2
to 2-1/2 inches (12-65 mm) in
diameter, and in continuous
lengths up to 150 feet (45 m).
To produce feedwater heater
tubing Plymouth has state-of-the-art
U-bending and stress relieving
equipment. Such tubing is used
in fossil, nuclear, geothermal
and hydroelectric power stations
throughout the world
