SS 321/321h Tubing Suppliers

Stainless Steel 321/321H tubing is austenitic stainless steel that is composed of nickel, chromium, and titanium. This alloy is a variation of 304 stainless steel and is known for its high resistance to corrosion and excellent high-temperature strength.

The “H” in the alloy’s name stands for “high carbon content,” which makes it suitable for high-temperature applications. On the other hand, the non-H version of the alloy has a lower carbon content and is suitable for general-purpose applications.

Properties of SS 321/321H Tubing

Stainless Steel 321/321H tubing exhibits excellent mechanical properties, making it suitable for a wide range of applications. Some of the properties of this alloy include:

• High Corrosion Resistance: Stainless Steel 321/321H tubing exhibits excellent corrosion resistance in a wide range of environments, including corrosive media such as acids and alkalis.
• High-Temperature Strength: This alloy is highly resistant to creep and oxidation at elevated temperatures, making it ideal for high-temperature applications.
• Excellent Weldability: Stainless Steel 321/321H tubing can be easily welded using conventional welding techniques, making it a preferred choice for many industries.
• Good Formability: This alloy can be easily formed into various shapes and sizes using standard methods, making it highly versatile.
