Shalan Steel is a reliable manufacturer and supplier of top-notch Alloy Steel 4140 Coil based in Kuala Lumpur, Malaysia. We cater to a variety of industries, including oil and gas, automotive, aerospace, power generation, and heavy engineering. Alloy Steel 4140 is a chromium-molybdenum low alloy steel celebrated for its outstanding strength, toughness, and wear resistance. Our coils are crafted using cutting-edge rolling and heat treatment techniques, all under strict quality control to ensure they meet ASTM and other international standards. Built for high-performance applications, our Alloy Steel 4140 coils deliver exceptional reliability, machinability, and durability, even in the toughest operational settings.
The composition of Alloy Steel 4140 includes carbon, manganese, chromium, and molybdenum, striking the perfect balance between hardness, tensile strength, and ductility. The chromium boosts hardenability and corrosion resistance, while molybdenum adds to high-temperature strength and wear resistance. Typically, these coils showcase tensile strengths between 850 and 1000 MPa, along with impressive fatigue resistance and impact toughness. Thanks to quenching and tempering processes, we refine the microstructure, ensuring consistent mechanical properties and dimensional stability for critical engineering tasks.
