Veer Flanges India based in Kolkata, makes and sells top-notch flanges for many industries. We focus on AISI 4140 flanges known for being strong, tough, and resistant to wear. These flanges work well in demanding fields like cars, planes, and oil & gas where they need to perform well and last long. At Veer Flanges, we aim to make products that are precise high-quality, and dependable.
AISI 4140 flanges come from a low-alloy steel with about 0.40% carbon, 0.80–1.10% chromium, and 0.15–0.25% molybdenum. This mix of metals gives the steel great toughness high tensile strength, and strong resistance to fatigue. These flanges have a tensile strength of 655 MPa and a yield strength of 415 MPa which shows how well they perform . They stand out because they resist wear harden well and have robust strength. This makes them a good fit for tough high-stress settings. You’ll often find these flanges in cars planes and oil & gas equipment where they need to last long and work well in harsh conditions.
