Performance Advantages of Xinzhe TP310H Tubing
• Enhanced Creep Strength: The controlled carbon range (0.04–0.10%) provides significantly higher creep rupture strength compared to TP310S.
• Oxidation & Carburization Resistance: High Chromium (25%) and Nickel (20%) content forms a protective oxide layer that resists scaling in moderately carburizing atmospheres.
• Metallurgical Stability: Our advanced solution annealing process prevents sigma phase embrittlement, ensuring long-term ductility in high-heat cycles.
• Wenzhou Manufacturing Excellence: Our facility utilizes state-of-the-art cold-rolling and cold-drawing equipment to achieve tight di

What Is a Seamless Stainless Steel TP310H Tube?

Seamless Stainless Steel TP310H Tube is a high-temperature, corrosion-resistant tube crafted from a single, solid billet of a high-chromium and high-nickel austenitic stainless steel. It is manufactured without a weld joint, ensuring superior structural integrity and reliability, especially under high-stress and high-temperature conditions. The”310H”designation refers to a specific grade that is a high-carbon version of Stainless Steel 310. This higher carbon content (0.04-0.10%) provides enhanced creep and stress-rupture properties at elevated temperatures, making it a preferred choice for applications where long-term high-temperature strength and stability are critical. This makes it a top choice for demanding applications in industrial furnaces, power generation, and heat treatment.

Key Features and Advantages

Stainless Steel 310H Seamless Tube offer a unique combination of benefits that make them invaluable in demanding high-temperature industries:

Excellent High-Temperature Strength: The higher carbon content provides superior creep and stress-rupture properties, ensuring long-term structural stability at temperatures exceeding 1100°F (593°C).

Outstanding High-Temperature Oxidation Resistance: The high chromium and nickel content provides superior resistance to oxidation and scaling in high-temperature air.

Resistance to Carburization: The alloy is highly resistant to carburization, which is crucial for applications in high-temperature furnaces and reducing atmospheres.

High Pressure and Temperature Tolerance: The seamless construction and robust material allow the tube to safely handle high internal pressures and extreme temperatures.

Good Weldability: The alloy can be readily welded using standard methods, and its balanced composition helps prevent hot cracking.
