Duplex 2304 Sheet exporter
Duplex 2304 Sheet exporter plays a crucial role in supplying high-quality stainless steel sheets known for their excellent corrosion resistance and mechanical strength. These sheets are made from a duplex stainless steel alloy, combining approximately 23% chromium, 4% nickel, and a balanced amount of molybdenum, offering superior durability compared to standard stainless steel grades. The unique microstructure of this material ensures enhanced performance in aggressive environments, making it a preferred choice for various industrial applications.
Manufactured as flat, rolled stainless steel sheets, these products are available in multiple thicknesses and sizes to meet diverse project requirements. The duplex 2304 grade provides a remarkable balance between austenitic and ferritic phases, resulting in improved resistance to stress corrosion cracking, pitting, and crevice corrosion. This makes it ideal for use in chemical processing, marine environments, and oil and gas sectors where exposure to chlorides and harsh chemicals is common.
Industrial buyers can expect sheets that conform to international standards such as ASTM A240 and EN 10088, ensuring reliable mechanical properties and dimensional accuracy. The exporter typically offers customization options including surface finishes like 2B or BA, as well as tailored cutting and packaging to facilitate seamless integration into manufacturing processes. This adaptability is critical for fabricators and engineers aiming to optimize performance and cost-efficiency.
The export readiness of these stainless steel sheets is underscored by stringent quality control measures, comprehensive certification, and compliance with global shipping regulations. Exporters ensure timely delivery through robust logistics networks and proper handling to maintain product integrity during transit. This commitment to quality and service supports industries worldwide in securing durable materials for infrastructure, construction, and heavy machinery applications.

Manufacturing Process & Heat Treatment of Duplex 2304
Annealing
The annealing process for Duplex 2304 involves heating the material to a temperature range of 1020°C to 1100°C, followed by a controlled cooling process. This treatment helps to relieve internal stresses, enhance ductility, and improve overall mechanical properties, making the steel more workable for subsequent manufacturing processes.
Forging
Forging of Duplex 2304 is typically performed at temperatures between 1100°C and 1250°C. This process involves shaping the steel through compressive forces, which aligns the grain structure and enhances the strength and toughness of the material. Post-forging, the material is often subjected to normalization to refine its microstructure.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Water or Oil | Increase hardness and strength |
| Tempering | 400 - 700 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 300 - 500 | Air | Eliminate residual stresses from previous processes |
The combination of these processes ensures that Duplex 2304 maintains its excellent mechanical properties and corrosion resistance, making it suitable for a wide range of industrial applications.
