2205 duplex stainless steel coil
2205 Duplex Steel Coil Introduction
2205 duplex steel is a high-strength, stainless, corrosion-resistant steel grade whose primary chemical composition includes approximately 22% of chromium, 5% of nickel, and 3% of molybdenum. Compared with conventional austenitic stainless steels, 2205 duplex steel has higher tensile and yield strengths, as well as better resistance to stress corrosion cracking.
2205 duplex steel coils are usually supplied in hot and cold rolled form, with common thicknesses ranging from 0.5mm to 50mm, and widths can be customized according to customer needs.
Quality control during production
- Raw Material Inspection: Each batch of raw materials is subject to strict chemical composition analysis and mechanical property testing to ensure compliance with the technical requirements of 2205 duplex steel.
- Intermediate process control: The thickness, width and surface quality of the coils are monitored during the hot and cold rolling process by online inspection equipment to ensure the stability of the production process and the consistency of the product.
- Final Product Inspection: Comprehensive testing of finished products, including chemical composition analysis, mechanical property testing, microstructure observation and non-destructive testing, etc., to ensure that the quality of products meets the standard requirements.
Advantages of 2205 stainless steel coil
Excellent corrosion resistance
Due to its high chromium and molybdenum content, 2205 duplex coils have much higher corrosion resistance than standard austenitic stainless steels such as 304 and 316. It performs particularly well in chloride-containing and seawater environments.
high strength
The yield strength of 2205 duplex steel coil is about 250MPa, which is twice as high as ordinary austenitic stainless steel, so it can be designed to reduce the wall thickness and weight, thus reducing the cost.
Good welding properties
2205 Duplex Steel Coil has good welding properties and does not require preheating or post heat treatment. However, in order to maintain its excellent corrosion resistance and mechanical properties, it should be properly heat treated after welding.
Good impact resistance
The duplex structure provides higher strength and toughness. The ferrite phase provides good impact resistance, while the austenite phase provides higher ductility and toughness.2205 Duplex coils maintain good impact resistance at low temperatures.
Processing and handling
2205 Duplex Steel Coil can be handled through a variety of processing methods, including cutting, bending, welding and machining. Due to its high strength and hardness, proper tools and techniques need to be used during processing to ensure quality and efficiency.
Application Areas
Duplex Stainless Steel is widely used in several applications due to its excellent mechanical properties and corrosion resistance. The following are some of the major applications of Duplex Stainless Steel:
