George Metals, located in Houston, USA, has earned a solid reputation as a reliable manufacturer and supplier of top-notch Duplex Steel Round Bars. With a strong focus on precision, quality, and customer satisfaction, this company caters to a variety of industrial sectors, providing premium-grade materials that adhere to global standards. George Metals is particularly known for its corrosion-resistant and high-strength Duplex Steel Round Bars, which are perfect for challenging environments. With a commitment to timely delivery and competitive pricing, they have built a strong rapport with clients in the oil and gas, marine, construction, and chemical processing industries, both in the United States and beyond.
Duplex Steel Round Bars are primarily made from a blend of austenitic and ferritic stainless steel, typically featuring around 22–25% chromium, 4–7% nickel, 3–5% molybdenum, along with trace elements like nitrogen. These bars strike a remarkable balance between mechanical strength and corrosion resistance. Their mechanical properties include a high yield strength of about 450 MPa and a tensile strength of around 620 MPa, along with good elongation and impact resistance. This unique dual-phase structure enhances their resistance to stress corrosion cracking, making Duplex Steel Round Bars exceptionally durable and well-suited for tough environments.
