310H stainless steel is an alloy known for its excellent resistance to oxidation and corrosion at high temperatures. It is commonly used in industries where materials are subjected to harsh environments, particularly at temperatures exceeding 1000°F (537°C). 310H stainless steel is an ideal choice for applications requiring durability and heat resistance, such as in the petrochemical, power generation, and heat exchanger industries.
Key Features of 310H Stainless Steel Sheet & Plate:
High-Temperature Resistance: 310H stainless steel is designed for use in high-temperature environments. It is capable of withstanding temperatures up to 2100°F (1149°C) in intermittent service and is commonly used in furnaces, kilns, and incinerators.
Corrosion Resistance: The alloy is highly resistant to a range of corrosive agents, making it ideal for high-temperature applications where corrosion from sulfur, chlorides, and other harmful chemicals is a concern.
Excellent Weldability: 310H stainless steel offers good weldability, especially in the annealed condition. Its low carbon content minimizes the risk of carbide precipitation during welding, enhancing its overall performance and longevity in welded applications.
Strength and Durability: It provides good mechanical strength at elevated temperatures, offering long-term durability in industrial applications where steel materials face continuous stress.
Resistance to Scaling: 310H is resistant to scaling and oxidation in environments where other materials may fail due to heat exposure. This makes it particularly useful in applications like heat exchangers and combustion systems.
Formability: Available in sheet and plate form, 310H can be easily fabricated into complex shapes and sizes for diverse applications, ensuring versatility in industrial designs.

Corrosion Resistance
Oxidation Resistance: The high chromium (24.0-26.0%) and nickel (19.0-22.0%) content in Stainless Steel Plate 310H enhances its resistance to oxidation. This makes it particularly suitable for applications involving continuous high temperatures and exposure to oxidizing agents.
Sulfuric Acid Resistance: Stainless Steel Plate 310H is well-suited for environments with sulfurous gases. Its resistance to sulfuric acid and other sulfur-containing compounds ensures longevity and reliability in harsh conditions.
Acid Resistance: The alloy’s composition provides robust resistance against acidic environments, including dilute acids. This makes it a reliable choice for chemical processing and other applications where exposure to acids is a concern.
Corrosion in High-Temperature Conditions: One of the standout features of 310H is its ability to maintain resistance to corrosion even at elevated temperatures. This property is crucial for components in high-temperature applications such as furnace parts, heat exchangers, and gas turbines.
Fabrication Data
Welding
Process Compatibility: Stainless Steel Plate 310H is weldable using common methods such as TIG (Tungsten Inert Gas), MIG (Metal Inert Gas), and Stick welding. The high chromium and nickel content contributes to good weldability.
Filler Material: Use filler materials such as ER310 or ENiCrFe-3 to match the composition of the base metal and maintain strength and corrosion resistance.
Preheating: Preheating is generally not required, but it can be beneficial to avoid thermal
