GENERAL PROPERTIES
Duplex 2205 is an exceptional ferritic-austenitic stainless steel, meticulously alloyed with 22% chromium, 3% molybdenum, and 5-6% nickel. This popular duplex grade boasts a yield strength that outshines typical austenitic grades by a significant margin. Renowned for its extraordinary fatigue strength, it offers unparalleled resistance to stress corrosion cracking, crevice corrosion, pitting, erosion, and general corrosion, even in the most demanding environments.
APPLICATIONS
- Chemical processing, transport, and storage - Ideal for pressure vessels, tanks, piping, and heat exchangers.
- Oil and gas exploration and processing equipment - Perfect for piping, tubing, and heat exchangers.
- Marine and other high chloride environments - Ensuring durability and longevity.
- Effluent scrubbing systems - Optimal for maintaining clean operations.
- Pulp and paper industry - Suitable for digesters, bleaching equipment, and stock-handling systems.
- Cargo tanks for ships and trucks - Providing reliable transportation.
- Food processing equipment - Ensuring hygienic and durable solutions.
- Biofuels plants - Supporting sustainable energy production.
STANDARDS
- ASTM/ASME: A240 UNS S32205/S31803 - Meeting rigorous international standards.
- EURONORM: 1.4462 X2CrNiMoN 22.5.3 - Reflecting European quality.
- AFNOR: Z3 CrNi 22.05 AZ - Adhering to French norms.
- DIN: W.Nr 1.4462 - Complying with German DIN standards.
CORROSION RESISTANCE
- Thanks to its high chromium, molybdenum, and nitrogen content, Duplex 2205 offers superior corrosion resistance compared to 316 and 316L in a wide variety of environments.
- Its composition provides high resistance to pitting and crevice corrosion, even in aggressive oxidizing and acidic solutions.
- Withstands chloride stress corrosion cracking and temperatures up to approximately 302°F (150°C).
- The presence of ferrite ensures robust performance in caustic environments.
HEAT RESISTANCE
- Like other duplex stainless steels, Duplex 2205 exhibits excellent oxidation resistance at elevated temperatures.
- However, it is prone to embrittlement when exposed to temperatures above 572°F (300°C), even for short durations. Therefore, it is not recommended for use above 572°F (300°C).
WELDING CHARACTERISTICS
- Exhibits good weldability.
- Generally, avoid welding without filler metal to prevent excessive ferrite formation.
HEAT TREATMENT
- Annealing temperature range is between 1868°F and 2012°F (1020°C to 1100°C).
- While Duplex 2205 cannot be hardened by heat treatment, it does work-harden effectively.
- Special precautions should be taken to account for its higher coefficient of thermal expansion, which may otherwise lead to warping and distortion.
PROCESSING - HOT FORMING
- Most producers recommend a maximum hot forming temperature between 2010°F and 2100°F (1100°C to 1150°C). Shape considerations are crucial as non-compact forms may cool unevenly, increasing the risk of cracking in cooler regions.
PROCESSING - COLD FORMING
- Duplex 2205 demonstrates exceptional formability across various fabrications. However, its high strength can present challenges. Even with adequately powered equipment, it is crucial to account for increased spring-back due to the grade's elevated strength.
MACHINABILITY
Duplex 2205 is somewhat more challenging to machine than the 300 series austenitic stainless steels. It demands higher cutting forces, leading to quicker tool wear. For optimal machining: A) Utilize powerful, rigid machines with robust tool and workpiece mounting, B) Minimize vibration by keeping tool extensions as short as possible, C) Use a nose radius on the tool, no larger than necessary, to maintain sharpness and strength, and D) Design machining processes to ensure cutting below the work-hardened layer from previous passes.
Features of 2205 stainless steel coils
- Type 2205 is a duplex (austenitic/ferritic) stainless steel enriched with chromium, molybdenum, and nitrogen, enhancing performance and corrosion resistance compared to 304 and 316 stainless steel. Its unique austenite/ferrite microstructure and alloying elements provide superior resistance to stress corrosion cracking, pitting, and ***-induced crevice corrosion. Alloy 2205 withstands oxidation up to 980°C, though it may become brittle at 300°C-1000°C over long periods. This versatile alloy is ideal for a wide array of applications in strip, coil, and sheet forms.
What are the commonly used surfaces of stainless steel coils?
The surface finish of 201 stainless steel coils varies based on cold rolling processes and post-rolling surface treatments. Common surface treatments include NO.1, 2B, 4, HL, 6, 8, BA, TR hard, heavy rolling bright 2H, polished bright, and others:
- NO.1: NO.1 surface is achieved through hot rolling, heat treatment, and pickling of stainless steel strips to remove black oxide scale. It has a silvery white matte finish and is typically used in heat-resistant and corrosion-resistant industries without high surface gloss requirements, such as alcohol production, chemical processing, and large containers.
- 2B: The 2B surface, refined by light rolling, is smoother and brighter than the 2D surface, with a surface roughness Ra value between 0.1 to 0.5μm. This finish offers the highest versatility, making it suitable for industries such as chemicals, papermaking, petroleum, medical applications, and architectural curtain walls.
- TR hard surface: TR (hard) stainless steel, including grades like 304 and 301, is used for high-strength, high-hardness items such as railway vehicles, conveyor belts, springs, and washers. By leveraging the work hardening properties of austenitic stainless steel, the strength and hardness of steel plates are enhanced through cold working techniques like rolling, without subsequent annealing, resulting in the distinctive TR hard surface.
- Re-rolled bright 2H: After the rolling operation, the stainless steel strip undergoes a sophisticated bright annealing process. Using a continuous annealing line allows for rapid cooling of the strip, which travels along the line at impressive speeds of 60-80m/min. This meticulous process results in a 2H re-rolled bright surface finish, ensuring the highest quality and brilliance.
- No. 4: The No. 4 surface offers an exceptional polishing effect, surpassing the brightness of No. 3. This finish is achieved by polishing cold-rolled stainless steel plates with a 2D or 2B surface, followed by sanding with a 150-180# grit belt. The final surface roughness (Ra) ranges between 0.2 and 1.5μm. The No. 4 surface is extensively used in applications such as restaurant and cooking equipment, medical instruments, architectural decorations, and various containers.
- HL: The HL or hairline surface finish is a distinctive texture often achieved by polishing with a 150-240# abrasive belt, as per the Japanese JIS standard. The Chinese GB3280 standard provides general guidelines but lacks specificity. HL finishes are predominantly used in architectural decorations, including elevators, escalators, and exterior walls, providing a sleek, sophisticated look.
- No. 6: The No. 6 surface is an enhanced version of No. 4, polished further with a Tampico brush or W63 grit material as specified by the GB2477 standard. This finish combines a metallic luster with softness, offering weak reflection and no imaging. Its excellent characteristics make it ideal for curtain walls, tassel decorations, and cooking supplies.
- BA: The BA (Bright Annealed) surface is achieved by bright heat treatment after cold rolling. This process involves annealing in a protective atmosphere to prevent oxidation, preserving the gloss of the cold-rolled surface. It is then polished with a high-precision smooth roller for heightened brightness. Surface roughness measures between 0.05-0.1μm, approaching a mirror finish. Suitable for diverse applications, BA surfaces are found in food utensils, household appliances, medical equipment, automotive parts, and decorative items.
- No. 8: The No. 8 mirror surface offers maximum reflectivity, free from abrasive particles. In the stainless steel deep processing industry, it is also known as 8K board. BA material serves as the raw input for mirror processing, requiring only polishing to achieve a stunning, beautiful finish. This surface is frequently used in building entrances and interior decorations for its aesthetic appeal.
