Product Description

0.1-6mm Cold Rolled Duplex 2205 Stainless Steel Sheet for Heat Exchanger Applications

Our factory supplies high strength duplex stainless steel 2205 sheets (0.1-6mm cold rolled). Compared with 316L/317L, 2205 offers superior pitting and crevice corrosion resistance, lower thermal expansion, and higher thermal conductivity, making it ideal for heat exchanger environments.

Problem Analysis

Austenitic steels like 316L often fail in heat exchangers due to chloride-induced pitting, high thermal expansion causing stress, and poor heat transfer efficiency.

Solution

Duplex 2205 sheets double the compressive strength of austenitic grades, reduce weight, and operate reliably from -50°F to +600°F. The higher thermal conductivity improves heat exchanger performance.

Specifications

Parameter	Details
Grade	2205, 2507
Thickness	Cold rolled 0.1-6mm; Hot rolled 3-60mm
Size	1219×2438, 1500×3000 mm, etc.
Finish	2B, BA, No.1, HL, No.4
Standard	ASTM A240M, ASME SA-240

Applications

Heat exchanger tubes, shell-and-tube exchangers, plate heat exchangers, and condenser systems in chemical and marine industries.

Technical Operation

The ferritic-austenitic microstructure resists chloride attack. Lower thermal expansion reduces thermal fatigue, while higher thermal conductivity speeds heat transfer.

Selection Guidelines

Select 2205 for chloride-rich environments ≤600°F. Choose 2507 for higher strength and extreme corrosion. Verify ASTM A240M certification.

Frequently Asked Questions

Q1: Can 2205 replace 316L in seawater coolers?

Yes, it offers far better pitting resistance.

Q2: Is welding allowed?

Yes, but follow low-heat input procedures.

Q3: What thickness for heat exchangers?

Usually 0.5-3mm cold rolled.
