Stainless Steel 304 / 304L Flanges Manufacturer, Supplier, and Stockists in India

Samay Steel and Engineering Co. is a well-established manufacturer, stockist, and exporter of high-quality Stainless Steel 304 / 304L Flanges, offering reliable solutions for a wide range of piping and industrial applications. Stainless Steel 304 is the most commonly used austenitic stainless steel, known for its excellent corrosion resistance, formability, and mechanical strength. Its low-carbon variant, 304L, provides improved weldability and resistance to intergranular corrosion, especially after welding, making both grades ideal for use in pressure piping and structural systems.

The company offers a complete range of Stainless Steel 304 / 304L Flanges including weld neck flanges, slip-on flanges, socket weld flanges, blind flanges, threaded flanges, and lap joint flanges. These flanges are manufactured according to global standards such as ASTM A182, ASME B16.5, and DIN norms, ensuring consistent performance, dimensional accuracy, and compatibility with other piping components. They are used extensively in industries like oil and gas, chemical processing, food and beverage, water treatment, and HVAC systems.

As a trusted stockist, Samay Steel and Engineering Co. maintains a large inventory of Stainless Steel 304 / 304L Flanges in various sizes, pressure ratings, and face types (such as raised face, flat face, and ring-type joint). With state-of-the-art manufacturing and in-house quality testing facilities, the company ensures that each flange undergoes thorough inspection for mechanical properties, chemical composition, surface finish, and pressure endurance. This guarantees that clients receive flanges that meet exact specifications and operational demands.

Samay Steel and Engineering Co. exports its Stainless Steel 304 / 304L Flanges to numerous countries worldwide, earning a strong reputation for quality and service. Their key export markets include Oman, Qatar, Saudi Arabia, UAE, and Kuwait in the Middle East; Spain and Germany in Europe; the USA and Canada in North America; and various industrial hubs across Africa.
