High-quality AISI 4140 Flanges for high-stress and high-temperature industrial applications are available from Harsh Flanges, a renowned manufacturer and supplier with headquarters in Mumbai, India. These flanges are made from AISI 4140 alloy steel, a versatile material perfect for critical operations, and are well-known for their strength, toughness, and fatigue resistance. Our AISI 4140 Flanges are extensively utilised in industries such as heavy engineering, power generation, and oil and gas, and they are manufactured in accordance with international standards. Harsh Flanges guarantees peak performance and enduring durability under demanding service conditions thanks to its sophisticated production capabilities, precise machining, and strict quality controls.
The chromium-molybdenum alloy steel used to make AISI 4140 flanges contains roughly 0.38–0.43% carbon, 0.75–1.00% manganese, 0.80–1.10% chromium, and 0.15–0.25% molybdenum. Outstanding strength, hardness, and fatigue and wear resistance are provided by this composition. Tensile strength of 655–1080 MPa, yield strength of 415–655 MPa, and good ductility with 20% elongation are among the mechanical characteristics. These flanges are ideal for applications requiring durability, impact resistance, and structural integrity over extended service periods because of their exceptional performance under high pressure and temperature.
