Anucha Metals is a specialized manufacturer and supplier of Alloy Steel F12 bars and rods in Bangkok, Thailand. These chromium-molybdenum alloy bars are known for their strong resistance to high-temperature environments and high-pressure service. Our F12 bars meet ASTM A182 standards and are widely used in power generation and petrochemical industries. With advanced forging and heat treatment capabilities, Anucha Metals ensures consistent mechanical strength, surface quality, and chemical stability across all sizes and grades.
Alloy Steel F12 typically contains 1 to 1.5% chromium, 0.4 to 0.6% molybdenum, and 0.1% carbon. The bars show tensile strength ranging from 415 to 585 MPa and yield strength between 205 and 250 MPa. They offer good creep resistance, high-temperature stability, and moderate hardenability. The alloy responds well to heat treatment, enhancing its mechanical performance in critical applications.
