321H stainless steel capillary Tube/Pipe

Technical Specifications of 321H Stainless Steel Capillary Tube

The 321H stainless steel capillary tube represents a specialized austenitic stainless steel grade, engineered with titanium stabilization to prevent carbide precipitation. This premium stainless steel capillary tube variant operates efficiently within 427-816°C (800-1500°F). Key characteristics include:

• Higher carbon content (0.04-0.10)
• Enhanced creep resistance
• Superior strength above 537°C (1000°F)
• Non-magnetic in annealed condition
• Titanium-stabilized composition
• Excellent resistance to intergranular corrosion
