Liam Steel is your go-to manufacturer and supplier of **Alloy Steel 4140 Coils** right here in **Manila, Philippines**. We pride ourselves on delivering top-notch, high-strength steel solutions tailored for tough industrial and structural needs. Our 4140 Coils are designed to provide exceptional toughness, hardness, and wear resistance, making them perfect for parts that face high stress, impact, and fatigue. With cutting-edge alloy steel processing and rigorous quality control, these coils guarantee consistent mechanical performance, precise dimensions, and a long lifespan. We cater to various industries, including automotive, machinery, construction, and manufacturing, ensuring our high-performance steel products meet international standards throughout the Philippines.
Our Alloy Steel 4140 Coils are made from **chromium-molybdenum alloy steel**, featuring about **0.38–0.43% carbon, 0.8–1.1% chromium, 0.15–0.25% molybdenum, and 0.75–1.0% manganese**. This combination gives them remarkable strength, hardness, and toughness. These coils can achieve **tensile strength up to 1080 MPa** and **yield strength around 850 MPa**, along with impressive fatigue resistance and dimensional stability. They also offer good machinability, weldability, and wear resistance, making them ideal for heavy-duty industrial applications that demand high-performance alloy steel.
