Latham Steel, located in Hamilton, New Zealand, stands out as a top manufacturer and supplier of Super Duplex Steel Bright Bars. They focus on delivering high-quality products that are built for strength, durability, and outstanding resistance to corrosion. These bright bars boast a sleek, polished surface finish achieved through cold working, which not only enhances their mechanical properties but also ensures precise dimensions. Latham Steel is committed to meeting rigorous international standards with each bright bar, making them perfect for tough industrial applications. Their combination of precision and superior performance makes these bars a go-to choice for industries that need dependable, long-lasting solutions in harsh and corrosive settings.
Super Duplex Steel Bright Bars are made up of about 22–25% chromium, 5–7% nickel, 3–4% molybdenum, and trace amounts of nitrogen, striking a balance between austenitic and ferritic phases. This unique composition offers remarkable resistance to pitting, crevice, and stress corrosion cracking, especially in environments rich in chlorides. On the mechanical side, these bright bars deliver high tensile strength, typically ranging from 850 to 1000 MPa, with yield strength around 550 to 650 MPa, while also maintaining good toughness even at low temperatures. The cold-worked bright finish enhances hardness and surface quality, making these bars perfect for precision components and structural applications.
