Renowned for its commitment to quality, Starc Metals delivers materials that are both precise and reliable, serving a variety of industries such as power generation, oil and gas, and petrochemicals. The company prides itself on adhering to strict international standards, providing products designed for durability and efficiency in challenging applications. With cutting-edge manufacturing capabilities and a strong emphasis on customer service, Starc Metals offers customized alloy solutions to clients throughout Australia and beyond, establishing itself as a trusted ally in engineering and industrial projects.
Alloy Steel F91 Bars and Rods are made up of chromium (8.0–9.5%) and molybdenum (0.85–1.05%) as their main alloying elements, along with smaller amounts of carbon, manganese, silicon, phosphorus, sulfur, vanadium, and nitrogen. This unique blend gives them remarkable resistance to high-temperature corrosion and oxidation. On the mechanical side, these bars and rods boast impressive tensile strength (at least 585 MPa), solid yield strength (minimum 415 MPa), and an elongation of no less than 20%. Their outstanding creep resistance and structural integrity at high temperatures make them perfect for long-term use in extreme conditions, ensuring they remain reliable and strong in high-stress industrial settings.

Alloy Steel F91 Bars and Rods are primarily used in high-temperature and high-pressure applications such as power plants, pressure vessels, and heat exchangers due to their strength and resistance to oxidation.
Alloy Steel F91 offers excellent tensile strength, high-temperature resistance, and good oxidation and corrosion resistance, making it ideal for demanding industrial applications.
Alloy Steel F91 Bars and Rods are primarily used in high-temperature, high-pressure environments where strength and durability are critical. Common applications include boiler components, superheaters, reheaters, and headers in power generation plants. In the oil and gas industry, they are found in pipelines, heat exchangers, and pressure vessels that must endure harsh operating conditions. The chemical and petrochemical industries utilize them for reactor parts and structural components exposed to corrosive substances. Their excellent creep resistance and thermal stability also make them suitable for heavy-duty mechanical and structural systems where long-term performance and reliability are essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
