About Duplex 2304 Stainless Steel Rebar
Stainless steel is categorized into martensitic, ferritic, austenitic, duplex stainless steel, and precipitation hardening stainless steel. Among these, duplex stainless steel is the most suitable for concrete structures. Duplex stainless steel contains both ferritic and austenitic phases, offering excellent mechanical properties and resistance to chloride stress corrosion. Over the past decade, advancements in smelting technology have reduced costs while improving performance, making stainless steel reinforcement a preferred choice in construction.
Why Choose Duplex 2304 Stainless Steel Rebar
Duplex 2304 is the most widely used stainless steel rebar for concrete structures. It contains 23% chromium and 4% nickel, forming a self-healing chromium-rich oxide film that ensures superior corrosion resistance. With a yield strength of 600MPa after processing, it also excels in elongation and elastic modulus. The cost of 2304 is lower than 2205 and 316 grades, offering better lifecycle cost efficiency while reducing dependency on nickel and molybdenum resources.

Mechanical Properties of 2304 Stainless Steel
| Property | Value |
|---|---|
| Tensile Strength (min) | 87 ksi (600 MPa) |
| Yield Strength 0.2% offset (min) | 58 ksi (400 MPa) |
| Elongation (% in 50mm, min) | 25 |
| Hardness (Brinell, max) | 293 |
| Hardness (Rockwell B, max) | 31 |
Cost and Performance Benefits
While duplex 2304 stainless steel rebar costs approximately 4-5 times more than carbon steel bars, it offers a service life exceeding 120 years. This significantly reduces maintenance costs, reconstruction expenses, and the need for additional anti-corrosion measures. For optimal cost control, use stainless steel reinforcement in critical structural components—increasing total project costs by only about 2% while substantially lowering lifecycle costs.
