FAQ's

What is 310H stainless steel tube?

310H stainless steel tube is a high-carbon variant of Grade 310, designed for high-temperature environments requiring superior strength, creep resistance, and oxidation stability. With its elevated nickel and chromium content, it offers excellent durability and corrosion resistance, even in atmospheres containing sulfur dioxide. Commonly used in furnaces, heat treatment equipment, and power generation systems, it performs reliably up to 1040°C in intermittent service and 1150°C in continuous operation.

The key difference between 310S and 310H stainless steel lies in their carbon content, which affects their behavior at high temperatures. Grade 310S has a lower carbon content (≤0.08%) for improved weldability and resistance to intergranular corrosion, making it suitable for fabricated or welded parts. In contrast, 310H contains higher carbon (0.04–0.10%), offering superior strength and creep resistance under elevated temperatures. Many products are dual-certified as 310S/310H, combining the advantages of both for versatile high-temperature applications.

The carbon content of stainless steel 310H tube is between 0.04% and 0.10%.

Stainless steel 310H tube is an iron-based alloy containing high levels of chromium (24–26%) and nickel (19–22%), which provide excellent oxidation and corrosion resistance. It also includes manganese (up to 2%), silicon (up to 0.75%), carbon (0.04–0.10%), phosphorus (up to 0.045%), and sulfur (up to 0.030%), with the balance being iron. This precise composition ensures superior strength and stability under high-temperature conditions.
