Hemi Metals, located in Hamilton, New Zealand, is a reliable manufacturer and supplier of top-notch Alloy Steel F12 Bars and Rods, designed for high-temperature and high-pressure industrial applications. This chromium-molybdenum alloy steel is specifically crafted to provide exceptional strength at elevated temperatures, resist oxidation, and ensure long-lasting mechanical reliability. With a focus on precise dimensions, controlled heat treatment, and rigorous quality standards, these bars and rods consistently perform well in demanding conditions. Hemi Metals caters to industries like power generation, petrochemicals, refineries, and heavy engineering, where durability, safety, and thermal stability are paramount.
Alloy Steel F12 typically consists of about 1.0–1.5% chromium and 0.45–0.65% molybdenum, along with carefully controlled levels of carbon, manganese, and silicon. This specific chemical makeup grants it impressive strength, good oxidation resistance, and outstanding creep performance at high temperatures. F12 bars and rods usually exhibit tensile strength ranging from 415 to 585 MPa and yield strength close to 205 to 310 MPa, while also maintaining good ductility, impact toughness, and thermal stability. The alloy is dependable under prolonged heat and pressure.
