Stainless Steel 904L Flanges Manufacturer, Supplier, and Stockists in India

Samay Steel and Engineering Co. is a leading manufacturer, stockist, and exporter of premium-quality Stainless Steel 904L Flanges, engineered to perform exceptionally in highly corrosive environments. Stainless Steel 904L is a non-stabilized austenitic stainless steel with a low carbon content and high levels of nickel and molybdenum. These elements provide superior resistance to strong reducing acids, such as sulfuric acid, and protection against pitting, crevice corrosion, and stress corrosion cracking, making it ideal for challenging industrial applications.

The company manufactures a comprehensive range of Stainless Steel 904L Flanges, including weld neck, slip-on, blind, threaded, socket weld, and lap joint flanges. These flanges are produced in compliance with global standards such as ASTM A182 and ASME B16.5, ensuring precision engineering, excellent pressure-handling capabilities, and long service life. Stainless Steel 904L flanges are widely used in industries such as chemical processing, offshore oil and gas, pharmaceuticals, pulp and paper, and marine environments due to their high corrosion resistance and durability.

As a well-equipped stockist, Samay Steel and Engineering Co. maintains a ready inventory of Stainless Steel 904L Flanges in various sizes, pressure classes (150#, 300#, 600#, and higher), and face types like Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ). Each flange undergoes stringent quality control checks including material testing, pressure testing, dimensional inspections, and surface finish evaluations to ensure they meet international and customer-specific standards.

Samay Steel and Engineering Co. exports its Stainless Steel 904L Flanges to a broad range of global markets. The company’s key export destinations include Oman, Qatar, Saudi Arabia, UAE, and Kuwait in the Middle East; Spain and Germany in Europe; the USA and Canada in North America; as well as several countries across Africa. Their strong global presence, supported by reliable shipping networks and expert documentation handling, allows them to fulfill large-scale and urgent international orders with consistency and professionalism.
