Super Duplex Stainless Steel 2205 2507 Seamless/Welded Pipe Price Per Ton

Duplex stainless steel, specifically grades 2205 and 2507, is a popular choice for various industrial applications, including pipes. These grades are known for their excellent combination of properties, including high corrosion resistance and strength.

Here's some information about Duplex Stainless Steel 2205 and 2507 pipes:

1. Duplex Stainless Steel 2205:
- Chemical Composition: Duplex 2205 consists of about 22% chromium, 5-6% nickel, 3% molybdenum, and 2% nitrogen. It also contains a balanced amount of ferrite and austenite phases.
- Properties: It offers excellent corrosion resistance in various environments, high mechanical strength, good weldability, and moderate resistance to stress corrosion cracking.
- Applications: Duplex 2205 pipes are commonly used in the oil and gas industry, chemical processing, pulp and paper production, and marine environments.

2. Duplex Stainless Steel 2507:
- Chemical Composition: Duplex 2507 has a higher chromium and molybdenum content than 2205, with approximately 25% chromium, 7% nickel, 4% molybdenum, and 0.3% nitrogen.
- Properties: It provides even greater corrosion resistance, higher strength, and enhanced resistance to pitting and crevice corrosion. This makes it suitable for more demanding applications.
- Applications: Duplex 2507 pipes are often used in offshore and marine applications, as well as in the chemical processing, petrochemical, and desalination industries.

Both grades are excellent choices for pipes that will be exposed to aggressive environments or high-pressure conditions. They offer a cost-effective solution compared to other high-alloy materials. When selecting between the two, consider the specific requirements of your application. Duplex 2507 is generally more suitable for more corrosive environments, while Duplex 2205 may suffice for less demanding conditions.
