A well-known producer and supplier of high-performance AISI 4130 Flanges for demanding applications in a range of industries, Harsh Flanges is situated in Mumbai, India. The AISI 4130 low-alloy steel used to make these flanges is renowned for its exceptional strength, toughness, and weldability. Our flanges meet international standards and are appropriate for use in critical systems because they are designed to withstand high temperatures and pressures. In order to ensure the highest levels of safety, durability, and performance in demanding working conditions, Harsh Flanges is dedicated to providing dependable, precisely machined flange solutions to industries including oil and gas, petrochemicals, aerospace, and power generation.
About 0.28–0.33% carbon, 0.40–0.60% manganese, 0.80–1.10% chromium, and 0.15–0.25% molybdenum make up AISI 4130 Flanges. This low-alloy steel has good ductility and elongation of about 20–25%, as well as outstanding tensile strength (700–950 MPa), yield strength (460–690 MPa), and impact resistance. Because of these mechanical characteristics, AISI 4130 can be used in high-temperature, high-pressure applications. Additionally, the material provides moderate corrosion resistance and good weldability, especially when heat-treated, which improves performance in corrosive and structurally demanding environments.
