Stainless Steel Pipe Grade 304
Stainless Steel Grade 304 pipe is the essential choice for fluid transport, pneumatic systems, and structural applications where hygiene and corrosion resistance are non-negotiable. Often referred to as 18/8 stainless, it has a high chromium and nickel content, ensuring a long-lasting durable finish that resists oxidation and maintains its structural integrity under pressure.
From industrial dairy pipelines to high-end architectural handrails, Grade 304 (EN 1.4301) provides a cost-effective, high-performance solution for both internal and external environments.

Key Characteristics of Grade 304 Stainless Steel Pipe
- Exceptional Hygiene: Non-porous surface that resists bacterial growth, making it the primary choice for food, beverage, pharmaceutical, and medical process lines.
- Corrosion Resistance: Highly durable against atmospheric corrosion and a wide range of organic and inorganic chemicals.
- Structural Rigidity: Provides excellent strength-to-weight ratios for pressure-bearing process frameworks.
- Ease of Fabrication: Offers superb weldability and can be bent or formed using standard industrial equipment.
- High-Temperature Stability: Maintains performance and oxidation resistance in temperatures of up to 870°C.
Common Applications of Grade 304 Stainless Steel Pipe
- Food & Dairy Processing: Hygienic liquid, powder, and steam transfer lines across automated production facilities.
- Brewing & Distilling: Fermentation tanks, cooling coils, and product transfer lines.
- Architectural Fabrication: Decorative handrails, balustrades, and high-end structural furniture.
- Automotive & Transport: Exhaust systems, fuel lines, and protective structural bars.
- Water Treatment: Durable piping for fresh water transport and filtration systems.
