Product Description
2B Finish Duplex 2205 Stainless Steel Sheet for Chemical Tanker Construction
Product Overview
Our 2B finish duplex 2205 sheets combine high strength, low thermal expansion, and excellent resistance to pitting and crevice corrosion, making them ideal for chemical tanker inner linings.
Problem Analysis
Chemical tankers using 316L stainless steel experience rapid pitting from organic acids and chlorides, plus weight inefficiency due to lower strength properties.
Solution
Duplex 2205 provides twice the yield strength of conventional stainless steels, enabling thinner, lighter tank walls. The 2B smooth finish prevents chemical adhesion and simplifies cleaning operations.
Technical Specifications
| Parameter | Details |
|---|---|
| Grade | 2205, 2507 |
| Thickness | 1-6mm cold rolled |
| Finish | 2B, BA, No.4 |
| Edge | Mill edge, cut edge |
| Standard | ASTM A240M, EN10028-7 |
Applications
- Chemical tanker cargo tanks
- Baffles
- Piping systems
- Manway covers
Technical Performance
The high molybdenum (3%) and nitrogen (0.15%) content forms a stable passive film. The duplex microstructure resists stress corrosion cracking under cyclic loading conditions.
Selection Guidelines
Select 2B finish for internal linings requiring smooth surfaces. Choose No.1 finish for structural supports. Ensure compliance with IMO chemical carrier regulations and standards.
Frequently Asked Questions
Q1: Is 2205 compatible with sulfuric acid?
Dilute concentrations only; use 2507 for higher concentrations.
Q2: Can we cut to custom sizes?
Yes, we support any custom dimensions and cutting requirements.
Q3: What is the maximum service temperature?
Continuous service: 600°F; intermittent service: slightly higher temperatures are acceptable.
