BA 8k 2205 S32750 Super Duplex Steel Plate Decorative Steel Plate
2507 is the most common “super” duplex grade.
Usage of Duplex 2507 should be limited to applications below 6000 F
(3160 C). Extended elevated temperature exposure can reduce both
the toughness and corrosion resistance of alloy 2507.The high
chromium, molybdenum, and nitrogen levels provide excellent
resistance to pitting, crevice, and general corrosion.the duplex
structure provides 2507 with exceptional resistance to chloride
stress corrosion cracking.
Duplex 2507 possesses excellent mechanical properties. Often a
light gauge of 2507 material can be used to achieve the same design
strength of a thicker nickel alloy. The resulting saving in weight
can reduce the overall cost of fabrication.
Super Duplex Corrosion Resistance, The high chromium and molybdenum
content of Super Duplex makes it extremely resistant to uniform
corrosion by organic acids like formic and acetic acid. Super
Duplex also provides excellent resistance to inorganic acids,
especially those containing chlorides.
• High resistance to chloride stress corrosion cracking
• High Strength
• Superior resistance to chloride pitting and crevice corrosion
• Good general corrosion resistance
• Suggested for applications up to 6000 F
• Low rate of thermal expansion
• Combination of properties given by austenitic and ferritic
structure
• Good weldability and workability

Characteristics and application |
2B | The surface brightness and flatness of 2B is better than 2D.then
through a special surface treatment to improve its mechanical properties.2B could nearly
satisfy comprehensive uses. |
NO.3 | Polished with abrasive belt of git#100#200,have better brightness
with discontinuous coarse stria,used as inner and external ornaments for
building,electrical appliances and kitchen utensils etc. |
NO.4 | Polished with abrasive belt of grit#150#180.have better brightness
with discontinuous coarse stria.but thinner than NO.3,are used as bathtub buildings
inner and external ornaments electrical appliances kitchen utensils and food
processing equipment etc. |
HL | Polished with abrasive belt of grit#150#320 on the NO.4 finish and
has continuous streaks, mainly used as buildings ornaments elevators, door of building,
frontal plate etc. |
BA | Cold rolled, bright annealed and skin-passed, the product have
excellent brightness and good reflexivity like mirror, kitchen apparatus, ornament etc. |
8K | The product have excellent brightness and prefer reflexivity can be
the mirror. |

Duplex Heat Resistance
SAF 2507 should be solution annealed and quenched after either hot
or cold forming. Solution annealing should be done at a minimum of
1925F. Annealing should be followed immediately by a rapid air or
water quench. To obtain maximum corrosion resistance, heat treated
products should be pickled and rinsed.
