321H Stainless Steel Pipes And Tubes
JIS 321h Stainless Steel Pipes And Tubes
321H Stainless Steel Pipes and Tubes Manufacturer, Stockholder And Supplier
Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304)
stabilized by Titanium (321) or Niobium (347) additions. These
grades are used because they are not sensitive to intergranular
corrosion after heating within the carbide precipitation range of
425-850°C. Grade 321 is the grade of choice for applications in the
temperature range of up to about 900°C, combining high strength,
resistance to scaling, and phase stability with resistance to
subsequent aqueous corrosion.
Grade 321H is a modification of 321 with a higher carbon content,
to provide improved high-temperature strength.
A limitation with 321 is that titanium does not transfer well
across a high-temperature arc, so is not recommended as a welding
consumable. In this case grade, 347 is preferred - the niobium
performs the same carbide stabilization task but can be transferred
across a welding arc. Grade 347 is therefore the standard
consumable for welding 321. Grade 347 is only occasionally used as
parent plate material.
Like other austenitic grades, 321 and 347 have excellent forming
and welding characteristics, are readily brake or roll formed and
have outstanding welding characteristics. Post-weld annealing is
not required. They also have excellent toughness, even down to
cryogenic temperatures. Grade 321 does not polish well, so is not
recommended for decorative applications.
Grade 304L is more readily available in most product forms, and so
is generally used in preference to 321 if the requirement is simply
for resistance to intergranular corrosion after welding. However
304L has lower hot strength than 321 and so is not the best choice
if the requirement is resistance to an operating environment over
about 500°C.
