Harsh Flanges is a well-known manufacturer and supplier of top-notch Carbon Steel Plate Flanges, proudly based in Mumbai, India. We focus on crafting durable and budget-friendly plate flanges that meet both national and international standards like ANSI, DIN, and BS. These flanges are flat, circular disks that are welded onto the ends of pipes, creating a straightforward and secure connection for low-pressure applications. Renowned for their strength, weldability, and affordability, our carbon steel plate flanges find their place in waterworks, oil & gas, construction, and various industrial piping systems. At Harsh Flanges, we put quality, precision, and customer satisfaction at the forefront of everything we do.
Our carbon steel plate flanges are typically crafted from materials like ASTM A105 or A516 Gr. 70, ensuring exceptional mechanical strength and durability. They boast a tensile strength ranging from 485 to 620 MPa and a minimum yield strength of 250 MPa. With impressive ductility and weldability, these flanges are perfect for structural and piping applications. The carbon content provides resistance to moderate pressure and temperature, making them suitable for general-purpose use. At Harsh Flanges, we rigorously test each product for dimensional accuracy, flatness, and material integrity to ensure they meet industry performance standards.
