Sahil Metals, located in Riyadh, Saudi Arabia, stands out as a top manufacturer and supplier of high-performance **Super Duplex Steel Hollow Bars**. These bars are specifically crafted for tough applications where strength, resistance to corrosion, and machinability are essential. Built to comply with international standards, they cater to a diverse array of industries throughout Saudi Arabia and the Middle East, including oil and gas, chemical processing, marine, and offshore engineering.
Typically, Super Duplex Steel Hollow Bars are made from grades such as S32750, S32760, and Zeron 100, which boast high levels of chromium, molybdenum, and nitrogen. These elements work together to provide remarkable resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. With a tensile strength ranging from about 750 to 930 MPa and impressive impact resistance, these bars also excel in weldability and maintain their dimensions even in harsh environments.

Yes, Super Duplex Steel Hollow Bars can withstand high temperatures due to their excellent strength and corrosion resistance. They are suitable for applications in environments up to around 300°C (572°F), depending on the specific alloy.
Super Duplex Steel Hollow Bars and Rods are manufactured through hot or cold working processes, including extrusion and forging, followed by heat treatment, cold drawing, and precision machining for enhanced strength and corrosion resistance.
Super Duplex Steel Hollow Bars have excellent natural corrosion resistance due to their high chromium and molybdenum content, making additional protective coatings generally unnecessary. However, in highly aggressive environments, coatings may offer extra protection.
You’ll often find Super Duplex Steel Hollow Bars being used in the production of valve bodies, pump shafts, heat exchanger tubes, pressure housings, and various structural components. Their hollow design helps to lighten the material without sacrificing strength, making them a smart choice for precision machining and high-load applications. These bars deliver outstanding reliability and durability in corrosive and high-pressure systems, ultimately extending the lifespan of equipment and cutting down on maintenance costs.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
