Product Description:
304 and 304L stainless steel tubes are the most versatile and widely used stainless steel grades in various industrial and commercial applications. Renowned for their excellent corrosion resistance, durability, and formability, these grades are ideal for environments where hygiene, temperature resistance, and long-lasting performance are essential.
304 Stainless Steel Tubes
Grade 304 is austenitic stainless steel known for its exceptional corrosion resistance and strength. It is often referred to as “18/8” stainless steel due to its composition of 18% chromium and 8% nickel.
Key Features
- Excellent Corrosion Resistance: Performs well in a wide range of environments, including atmospheric and chemical exposures.
- High Strength and Durability: Suitable for structural and pressure applications.
- Good Formability: Easily fabricated and welded.
- Temperature Resistance: Performs well in cryogenic and high-temperature conditions up to 870°C.
Applications
- Food processing and dairy equipment
- Heat exchangers
- Pharmaceutical and chemical industries
- Kitchenware and utensils
- Architectural applications (railings, frames)
304L Stainless Steel Tubes
Grade 304L is the low-carbon version of 304, designed to provide better weldability and minimize the risk of intergranular corrosion.
Key Features
- Low Carbon Content: Reduces carbide precipitation during welding, making it ideal for welded applications.
- Enhanced Corrosion Resistance: Performs exceptionally well in chemical environments and high-moisture areas.
- High Durability: Retains strength and toughness even in low temperatures.
- Ease of Fabrication: Similar machinability and workability to Grade 304.
Applications
- Piping systems for chemical and pharmaceutical industries
- Heat exchangers and condensers
- Marine applications
- Storage tanks and pressure vessels
- Construction and infrastructure projects
