Veer Flanges, based in Kolkata, India, is a trusted manufacturer and supplier of **SS400 Flanges**, providing strong and economic solutions for diverse structural and piping use. SS400 is a common structural-grade carbon steel with good mechanical strength and weldability. Veer Flanges produces SS400 flanges in various types and sizes—e.g., weld neck, slip-on, blind, and threaded—for use in the construction, water treatment, engineering, and fabrication industries. With an emphasis on accuracy, quality assurance, and timely completion, Veer Flanges meets domestic and international customers with flanges according to JIS, DIN, and other international specifications.
**SS400 Flanges** are manufactured from SS400 steel, Japanese JIS G3101 standard carbon steel grade having mostly iron, together with trace amounts of carbon (≤0.25%), manganese, phosphorus, and sulfur. These flanges generally have a tensile strength of 400–510 MPa and yield strength of about 245 MPa. SS400 is weldable, machinable, and formable, with it being appropriate for many fabrication processes. While not corrosion-resistant as in the case with stainless steel, it can be galvanized or coated to provide protection when used in outdoor or humid conditions.
Veer Flanges, a leading supplier in Kolkata, India, offers an extensive selection of SS400 Flanges, including weld neck flanges, slip-on flanges, blind flanges, threaded flanges, and lap joint flanges. Designed for diverse industrial applications, our high-quality inventory and commitment to exceptional service make us a trusted choice for flange products in the region.
