Product details
Stainless Steel 304 Backing Rings Sagar Steel Corporation is a leading manufacturer, supplier, and global exporter of SS 304 Backing Rings and stainless steel backing flanges. Our 304 grade rings are precision-machined and designed to provide exceptional strength, leak-proof sealing, and corrosion resistance in industrial piping systems. Manufactured to ASME, ANSI, DIN, and EN standards, our backing rings are ideal for stainless steel pipelines, water systems, chemical processing units, and food-grade applications. A backing ring/flange is a drilled flat collar used to bolt one flange to another, providing mechanical support, alignment, and load distribution. In piping systems, a backing ring may be used behind a flange for stabilization or as a “loose backing flange Backing rings made of grade 304 stainless steel (also known as UNS S30400 / AISI 304) offer good corrosion resistance, good formability and weldability. Typical chemical composition for 304: ~18-20% Cr, ~8-11% Ni, C ≤ 0.08%. Tensile strength ~515 MPa, yield ~205 MPa for 304 in certain forms.
