Sagar Prakash Alloys is a leading Duplex Steel S31803 Forging supplier and stockist. Our company specializes in providing the finest grade of forged products to customers in various industries. We offer a wide range of Duplex Steel 2205 forging that is highly durable, corrosion-resistant, and incredibly strong.
Our duplex steel forgings are available in two distinct grades: S31803 and S32205. Duplex Steel S31803 Forgings differ in chemical composition, with S32205 having higher chromium and molybdenum content. This results in improved corrosion resistance and strength. S31803 material offers good weldability but may have slightly lower corrosion resistance. Both alloys excel in challenging environments and are popular for diverse industrial applications, making them valuable assets in the forging industry.

To enhance the properties of Duplex SAF 2205 stainless steel forgings, we subject them to specific heat treatment processes. The recommended annealing temperature is 1040℃ (1900°F), with water quenching preferred for rapid cooling. The hot forming range is 1200-955°C (2190-1750°F), while cold forming requires full annealing and quenching. Our forgings are compatible with various welding processes, including MMA, MIG, TIG, FCAW, SAW, and PAW. They can be seamlessly welded to carbon, low alloy, or austenitic stainless steel.

Additionally, the maximum interpass temperature during welding is 150°C (300°F). Interestingly, preheating is not necessary, and post-weld heat treatment is generally not recommended. This aspect provides flexibility in welding conditions and emphasizes the robust nature of Duplex SAF 2205 stainless steel forging.

Uses of Duplex Steel S31803 Forging
Duplex Steel ASTM A182 F51 forging is widely used in various industries and applications due to its superior strength and durability. Some of the common uses of these forging are as follows:
- Offshore and marine applications
- Chemical and petrochemical industries
- Pulp and paper industry
- Oil and gas industry
- Power generation industry
- Food processing industry
Forging Duplex Steel requires accurate heating between 950-1150°C, followed by rapid shaping through compression. The process must be completed within hours to prevent oxidation, preserving the steel's mechanical strength and corrosion resistance. Proper temperature control and timely execution are crucial for maintaining the material's integrity during forging.
Duplex Steel S32205 Forgings are available in various shapes and sizes to meet specific requirements. Some common shapes include round, circle, square, rectangle, and hexagon. Sizes range from small to large, depending on the application.
Choosing the right Duplex Steel 2205 Forgings is important in enhancing your industrial applications' overall performance and efficiency. Sagar Prakash Alloys provides top-quality, accurate Duplex steel forging, tested and certified to meet your needs.
