Steve Flanges is a reliable manufacturer and supplier located in Canberra, Australia, with a focus on high-performance AISI 4140 Flanges. These flanges are made from top-quality alloy steel AISI 4140, which is celebrated for its remarkable strength, toughness, and resistance to wear. Built to handle extreme pressure and temperature conditions, AISI 4140 Flanges are perfect for tough industrial applications. At Steve Flanges, every product goes through rigorous quality control and precise machining, ensuring that the flanges are durable, accurately sized, and resistant to corrosion, all while meeting international standards for reliability and longevity in critical engineering systems.
AISI 4140 Flanges are crafted from chromium-molybdenum alloy steel, which contains about 0.40% carbon, 0.8–1.1% chromium, and 0.15–0.25% molybdenum. This specific blend gives them outstanding mechanical properties, including high tensile and yield strength, excellent toughness, and good fatigue resistance. These flanges also show impressive resistance to impact, abrasion, and deformation. Heat treatment processes like quenching and tempering further boost their hardness and stability, making them ideal for high-stress and high-temperature environments while ensuring reliable performance and structural integrity.
