Liam Steel, based in Manila, Philippines, has earned a solid reputation as a reliable manufacturer and supplier of Alloy Steel 4140 Foil. This material is celebrated for its remarkable strength, toughness, and versatility. With a blend of chromium and molybdenum, this low-alloy steel is perfect for applications that demand high fatigue strength, abrasion resistance, and impact toughness. Catering to sectors like aerospace, automotive, and heavy machinery, Liam Steel delivers top-notch 4140 foil products that adhere to strict international standards. Their dedication to quality and customer satisfaction has made them a go-to source for Alloy Steel 4140 Foil, both in the Philippines and beyond.
Alloy Steel 4140 Foil is a low-alloy steel that typically contains around 0.38–0.43% carbon, 0.80–1.10% chromium, and 0.15–0.25% molybdenum, along with specified amounts of manganese, silicon, phosphorus, and sulfur. This unique composition gives it impressive tensile strength (up to 1000 MPa), yield strength (up to 750 MPa), and elongation (20–25%) when quenched and tempered. The foil is known for its excellent machinability (65% relative to AISI 1212), good weldability, and high fatigue resistance, making it a great choice for precision components that require both strength and toughness.
