Stainless Steel Flange AISI 304 | EN 1092-1 (DIN 2576)

At UTMK, you can order certified Stainless Flanges for secure, corrosion-resistant pipe connections in critical industrial and commercial applications. These flat, weld-on flanges are manufactured from high-grade AISI 304 stainless steel to precise European standards, ensuring reliable performance and long service life. They represent a fundamental component for building and maintaining robust piping systems across a wide range of industries.

Technical Specifications

Stainless steel flanges from our assortment are manufactured in strict accordance with leading industry standards, using one of the most versatile and reliable steel grades available. The key technical characteristics are summarized below, providing the essential data needed for engineering and procurement specifications. This ensures full compatibility with existing systems and regulatory requirements.

Core Advantages of Stainless Steel Flanges

• Exceptional Corrosion Resistance: Made from AISI 304 grade steel, these flanges naturally resist rust and corrosion from atmospheric conditions and many chemical agents, ensuring a long and reliable service life in demanding environments.


• High Strength and Durability: With a tensile strength of 500-700 MPa, stainless steel flanges provide robust and secure connections capable of withstanding significant mechanical stress and operational pressures, reducing maintenance needs.


• Hygienic and Non-Reactive Surface: The smooth, non-porous surface of stainless steel is easy to clean and sanitize, preventing bacterial growth. Its inert nature ensures it does not react with or contaminate the products it comes into contact with, making it ideal for food, beverage, and pharmaceutical applications.


• Excellent Weldability and Fabricability: AISI 304 steel can be easily welded using all standard fusion methods without requiring pre-heating or post-weld annealing in most cases. This simplifies installation, modification, and repair, saving time and labor costs on-site.

Spheres of Application

The unique combination of corrosion resistance, strength, and hygiene makes stainless steel flanges suitable for a diverse range of demanding applications.

• Food & Beverage Production: Essential for connecting pipes, tanks, and processing equipment in hygienic environments. The material is fully compliant with European Framework Regulation (EC) 1935/2004 for materials in direct contact with food products.


• Water Treatment & Distribution: Widely used for securing connections in municipal and industrial water systems, including potable water and wastewater treatment, where long-term corrosion resistance is a critical requirement.


• Chemical Processing: Suitable for systems handling moderately aggressive organic acids (e.g., acetic acid) and various oxidizing environments where the properties of AISI 304 provide sufficient resistance.


• Architectural & Structural Systems: Employed in exposed structural pipework and building facades where both mechanical strength and a clean, aesthetic appearance are important design considerations.


• Industrial-Style Furniture: A popular choice for DIY enthusiasts and furniture makers to create robust mounting points for tabletops, benches, and shelving units, delivering an authentic industrial look.


• Custom Shelving & Racks: Used to mount pipes for durable wall shelves, wine racks, or bathroom towel rails that combine a rustic aesthetic with practical, long-lasting function.
