With a strong emphasis on quality assurance and customer satisfaction, Aung Metals caters to a diverse array of industries, including oil and gas, petrochemical, marine, and construction, providing tailored solutions to meet various project needs both in Myanmar and beyond.
Duplex Steel Round Bars are made up of roughly 22–25% chromium, 4–7% nickel, 3–5% molybdenum, and a balanced mix of iron, along with nitrogen, manganese, and silicon to boost performance. This distinctive dual-phase microstructure grants them remarkable strength, toughness, and resistance to corrosion, particularly against chloride stress corrosion cracking and pitting. These bars showcase impressive mechanical properties, with high tensile strength (around 620–880 MPa), yield strength (≥450 MPa), and excellent elongation (up to 25%). Such attributes make Duplex Steel Round Bars perfect for demanding industrial applications that require heavy-duty performance.

Choose Stainless Steel 316 Rectangular Bars based on their resistance to corrosion, particularly in marine and chemical environments, and ensure they meet strength and durability requirements for your specific application. Consider factors like size, shape, and any applicable industry standards.
Yes, Stainless Steel 316 Rectangular Bars can be welded using standard welding techniques. Their excellent weldability is enhanced by their low carbon content, which minimizes the risk of carbide precipitation.
Stainless Steel 316 Rectangular Bars typically do not require additional corrosion protection coatings due to their inherent corrosion resistance. However, for extreme environments, coatings can provide added protection against aggressive chemicals or wear.
Across various industries that prioritize strength and corrosion resistance, Duplex Steel Round Bars are a go-to choice. They’re frequently utilized in chemical processing, marine engineering, oil and gas exploration, the paper and pulp sector, and desalination plants. Their robust resistance to pitting, crevice corrosion, and stress cracking makes them ideal for offshore platforms, heat exchangers, pressure vessels, and structural components. In construction and architectural projects, these bars serve as reinforcement and load-bearing elements in environments that can be quite harsh. The blend of mechanical durability and cost-effectiveness makes Duplex Steel Round Bars a favored material in modern industrial engineering solutions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
