Products We Offer
Stainless Steel 304 Pipe
Stainless Steel 304 Pipe is the most widely used stainless steel piping product, known for its excellent corrosion resistance, durability, and versatility. Made from an austenitic alloy containing 18% chromium and 8% nickel, Grade 304 offers strong resistance to oxidation, chemicals, and atmospheric conditions, making it suitable for a wide range of indoor and outdoor applications.
This pipe is commonly used in industries such as food and beverage, chemical processing, water treatment, construction, and automotive. Its non-reactive surface makes it ideal for sanitary environments, while its ease of fabrication and weldability allow for seamless installation and maintenance.
Stainless Steel 304 Pipe is available in various types—including seamless, welded, and ERW—with a range of sizes, wall thicknesses, and surface finishes to meet different industrial and commercial needs. It maintains excellent mechanical strength even at elevated temperatures and offers a long service life with minimal maintenance.
Whether for structural support, fluid transport, or high-purity applications, Stainless Steel 304 Pipe delivers reliable performance, aesthetic appeal, and cost-effectiveness, making it a trusted choice for engineers, builders, and manufacturers worldwide.
