High Strength 20mm Diameter Stainless Steel 2205 Round Bar Duplex Stainless Steel 2205 Bar Material Corrosion Resistant

‌Duplex stainless steel 2205 standard number: ASTM A240/A240M--01 Duplex stainless steel 2205 alloy is a duplex stainless steel composed of 22% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. It has high strength, good impact toughness and good overall and local stress corrosion resistance.

2205 stainless steel is a duplex stainless steel‌, in which the ferrite phase and austenite phase account for half of the solid quenching structure. This material is composed of 22% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy, and has high strength, good impact toughness and good overall and local stress corrosion resistance.

Chemical composition of the material
The chemical composition of 2205 stainless steel includes:

Chromium (Cr): 24.0-26.0%
Nickel (Ni): 6.0-8.0%
Molybdenum (Mo): 3.0-5.0%
Copper (Cu): maximum 0.5%
Iron (Fe): balance.

Performance characteristics of the material
2205 stainless steel has the following performance characteristics:

High strength: Its yield strength is more than double that of ordinary austenitic stainless steel, suitable for designs that need to reduce weight.
Good impact toughness: suitable for low temperature environments.
Good stress corrosion resistance: suitable for corrosive environments.
Applicable temperature range: -50°F/+600°F. Application areas
2205 stainless steel is widely used in the following areas:

Oil and gas pipelines, heat exchanger pipes
Sewage treatment systems
Pulp and paper industry classifiers, bleaching equipment, storage and processing systems
Rotating shafts, press rolls, blades, impellers, etc. in high-strength corrosion-resistant environments
Food processing equipment
