Isis Metals stands out as a top manufacturer and supplier located in Manila, Philippines, focusing on high-quality Super Duplex Steel Flat Bars. Known for their remarkable strength, durability, and resistance to corrosion, these flat bars are designed to excel in tough industrial and marine settings. Isis Metals caters to a diverse array of industries, including oil and gas, petrochemical, construction, power generation, and marine sectors. With cutting-edge production capabilities and a dedication to quality, the company guarantees that its Super Duplex Steel Flat Bars comply with international standards, ensuring outstanding performance, longevity, and consistent quality across all applications.
Super Duplex Steel Flat Bars are primarily made up of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen, all balanced with iron and trace elements. This unique dual-phase microstructure of ferrite and austenite grants them excellent mechanical strength and corrosion resistance. The bars showcase impressive tensile strength (around 800–1,000 MPa), superior yield strength, and exceptional toughness, even in low temperatures. They also provide remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking, making them perfect for aggressive, chloride-rich, and high-pressure industrial environments.

Yes, Super Duplex Steel Flat Bars are highly recyclable. Due to their composition and durability, they can be reused in various industries without compromising their properties or performance.
Super Duplex Steel Flat Bars are generally not suitable for cryogenic applications due to their brittleness at extremely low temperatures. Materials like austenitic stainless steel are often preferred for such uses.
Yes, Super Duplex Steel Flat Bars are suitable for underground applications due to their excellent corrosion resistance, especially in harsh, corrosive environments such as soil or groundwater exposure.
Isis Metals’ Super Duplex Steel Flat Bars find extensive applications in industries that demand high strength and corrosion resistance. In the oil and gas sector, they are essential for pipelines, pressure vessels, and offshore platforms. The chemical and petrochemical industries utilize them in process equipment, heat exchangers, and storage tanks that face harsh chemicals. In marine engineering, they are ideal for ship components, shafts, and fasteners that are exposed to seawater. Additionally, these flat bars are employed in desalination plants, power generation systems, and various construction projects.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
