Product Description

Product Characteristics

 

Okay, let's review the key product characteristics of 2205 duplex stainless steel flat bar:

Material Composition:

• 2205 duplex stainless steel is a two-phase alloy containing ~50% austenite and ~50% ferrite
• Major alloying elements are chromium (21-23%), nickel (4.5-6.5%), and molybdenum (2.5-3.5%)
• Also contains nitrogen (0.10-0.22%) to stabilize the austenite phase

Mechanical Properties:

• High strength - Yield strength of 450-550 MPa, tensile strength of 620-780 MPa
• Good ductility - Elongation of 25-35%
• Hardness of 27-32 HRC

Corrosion Resistance:

• Excellent pitting and crevice corrosion resistance
• Good resistance to stress corrosion cracking
• Suitable for marine, chemical, and other corrosive environments

Physical Characteristics:

• Density of 7.8 g/cm³
• Thermal conductivity of 15 W/m·K
• Coefficient of thermal expansion of 13 x 10⁻⁶/°C

Surface Condition:

• Hot rolled, pickled, and supplied in a mill finish
• Can be further ground, polished, or sanded as needed

Dimensional Tolerances:

• Thickness: ±0.50 mm
• Width: ±1.0 mm
• Length: ±50 mm

The combination of high strength, corrosion resistance, and workability makes 2205 duplex stainless steel flat bar well-suited for applications in the oil and gas, chemical, marine, and other industrial sectors. The duplex structure provides an ideal balance of properties compared to standard austenitic stainless steels.
