George Metals, based in Houston, USA, stands out as a top manufacturer and supplier of Incoloy 330 Bars and Rods. These products are celebrated for their remarkable resistance to oxidation and carburization, along with impressive strength at high temperatures. Incoloy 330 (UNS N08330) is a specialized nickel-iron-chromium alloy crafted for high-temperature furnace applications and thermal processing systems. George Metals provides these bars and rods in a variety of sizes, finishes, and tolerances, all adhering to international standards like ASTM B511/B535. Their outstanding durability under thermal cycling and mechanical stress makes them perfect for the chemical, heat treating, and petrochemical sectors.
Incoloy 330 Bars and Rods from George Metals are made up of about 35–37% nickel and 17–20% chromium, with balanced amounts of iron, silicon, and manganese. This alloy boasts a tensile strength of around 600 MPa, a yield strength of about 250 MPa, and impressive elongation (≥30%), even at temperatures over 1150°C (2100°F). It effectively resists scaling, oxidation, and carburization in high-temperature environments. The bars come in either an annealed or cold-drawn state, ensuring they are easy to work with and weld while maintaining their shape and performance in extreme conditions.
