201 304 316 321 347 PVC Coated Stainless Steel Tubing | BA Stainless Steel Coiled Tubing For Water Supply

Stainless steel tubing is widely used in various industries due to its excellent corrosion resistance, strength, and durability. When combined with a protective PVC coating, stainless steel tubing offers additional protection against environmental factors, making it ideal for water supply systems and other demanding applications. This article discusses different grades of stainless steel tubing (201, 304, 316, 321, 347), focusing on their material composition, specifications, chemical composition, mechanical properties, key features, applications, and equivalent grades.

Material

The stainless steel tubing covered here includes commonly used grades:

• 201: Economical grade with good corrosion resistance, mainly used where cost is a consideration.
• 304: The most commonly used austenitic stainless steel with excellent corrosion resistance and good formability.
• 316: Contains molybdenum for better corrosion resistance, especially against chlorides and marine environments.
• 321: Stabilized grade with titanium added to improve resistance against intergranular corrosion.
• 347: Similar to 321 but stabilized with niobium, offering resistance to corrosion and high temperatures.

PVC coating on stainless steel tubing provides an extra layer of protection from abrasion, moisture, and other external factors.
