Phanuphong Steel and Plates stands out as a top-notch manufacturer and supplier of high-quality steel products in Bangkok, Thailand, serving a variety of industrial and engineering sectors. One of their standout products is the Alloy Steel Coil, celebrated for its exceptional strength, heat resistance, and durability in tough conditions. Designed to meet international standards, these coils come in different grades, thicknesses, and finishes to fit a wide range of applications. With a strong focus on quality, precision, and timely delivery, Phanuphong provides alloy steel solutions to clients in the automotive, construction, oil & gas, and heavy machinery industries throughout Thailand and Southeast Asia.
Alloy Steel Coil is crafted from carbon steel that’s enhanced with alloying elements like chromium (0.5–9%), molybdenum (0.2–1%), nickel (0.3–5%), manganese, and vanadium. These additions significantly boost strength, wear resistance, toughness, and heat resistance. While mechanical properties can vary by grade, they typically feature yield strength ranging from 310–690 MPa and tensile strength between 550–850 MPa. When heat-treated, alloy steel coils can achieve remarkable impact resistance and fatigue strength. They also maintain good formability and weldability, making them perfect for both structural applications and high-temperature environments that demand long-lasting performance and durability.
