GRADE 2205 DUPLEX
This alloy has a microstructure of austenite and ferrite
(duplex) due to its chemical balance. The addition of
nitrogen provides strength levels close to 80% higher
than 304 with superior corrosion properties. The alloy
chromium and moly content provides superior pitting and
crevice corrosion properties and excellent stress
corrosion cracking resistance.
GRADE 316 LN
This alloy has a lower chromium content, higher nickel
than 304, and a 2% moly addition. The latter enhances
the corrosion resistance found in harsh environments,
especially halogens (chlorides). It offers superior
resistance to pitting or crevice corrosion failures
typical to high salt of coastal areas. The alloy is
austenitic providing excellent formability, weldability,
and cryogenic ductility. In addition, this grade has
higher creep strength; higher stress ruptures strength
and improved tensile strength as compared to 304 type
alloys.
EnduraMet™
32Stainless is a high-manganese, low-nickel,
nitrogen strengthened austenitic stainless steel. By
means of solid solution strengthening, the nitrogen
provides significantly higher yield and tensile strength
as annealed without adversely affecting ductility,
corrosion resistance or non-magnetic properties. In the
hot rolled unannealed condition, yield strengths of 75
ksi (518 MPa) or higher can be achieved for bar
diameters up to 2 in. (50.8 mm). EnduraMet 32 stainless
may be considered for rebar in bridge decks, barrier and
retaining walls, anchoring systems, chemical plant
infrastructure, coastal piers and wharves, bridge
parapets, sidewalks and bridge pilings. Because of its
low magnetic permeability, it may also be considered for
concrete rebar applications in close proximity to
sensitive electronic devices and magnetic resonance
medical equipment. The higher strength capability, 75
ksi (518 MPa) minimum yield strength, of EnduraMet 32 is
an added economical advantage. |
