Stainless Steel 347H Sheet, Plate, and Coil

Stainless Steel 347H sheet, plate, and coil are designed for high heat and tough service conditions. These products are stabilized with columbium, which prevents carbide during heating. This feature improves strength and keeps the material stable at high temperature. Even after long exposure to heat, stainless steel 347H plates resist intergranular corrosion. SS 347H sheets perform well in harsh and corrosive settings. They resist rust, cracking and surface damage under pressure. These products work well where heat, moisture, and chemicals are present at the same time. This makes them reliable for long-term industrial use. The chemical mix includes chromium, nickel, carbon, manganese, silicon, phosphorus, sulfur, columbium, and iron. Each element supports strength, heat resistance, and long service life. The higher carbon level in 347H improves creep strength at high temperatures. This balance of elements allows the material to hold shape and strength over time.

ASTM A240 TP347H Stainless Steel Plates offer strong mechanical support under heat stress. They maintain strength even when exposed to long heating cycles. These plates also resist chemical attack, oxidation, and thermal cracking. This means they can handle tough work environments. Stainless Steel 347H Plates work well in places that are constantly exposed to heat and pressure. It doesn't lose strength easily when it's in use. Their stable structure keeps the grain from getting damaged. This improves safety and reduces the risk of failure. These plates are widely used in petrochemical plants and oil and gas systems. They support piping, pressure vessels, and heat exchangers. Chemical plants use them for reactors and storage tanks. Power plants rely on them for boilers and furnace parts. The aerospace industry uses these plates for heat-exposed components. The pharmaceutical sector values their clean surface and corrosion control. They are used in digesters and recovery systems at pulp and paper mills. Food processing plants use them due to their strength and cleanliness. Stainless Steel 347H Plate materials can handle heavy loads and big changes in temperature. They stay stable even when the temperature changes. Their reliability makes them suitable for jobs where failure is not an option.

Frequently Asked Questions

What are the main differences between SS 347 and SS 347H plates? +

The main difference lies in carbon content. SS 347H plates contain higher carbon than SS 347 plates, which improves strength during prolonged heat exposure. SS 347 is preferred for general corrosion resistance, while SS 347H is selected when higher heat resistance and load-bearing strength are required.

Why is Stainless Steel 347H preferred for high-temperature structural applications? +

Stainless Steel 347H plates maintain strength and resist deformation at elevated temperatures. Columbium stabilization prevents grain damage caused by heat, keeping the structure stable under continuous thermal stress and pressure. This makes the material ideal for high-temperature structural systems.

What industries typically use SS 347H plates? +

SS 347H plates are widely used in oil and gas plants, petrochemical and chemical processing units, and power generation systems such as boilers and heat exchangers. They are also used in aerospace, food processing, and pharmaceutical industries where heat resistance and strength are critical.

What mechanical properties make SS 347H plates heat-resistant? +

SS 347H plates offer excellent creep resistance and retain tensile strength during long-term heat exposure. The alloy resists thermal cracking, stress damage, and deformation, allowing it to perform reliably in demanding high-temperature operating conditions.

What size and thickness options are available for SS 347H plates? +

Stainless Steel 347H plates are available in widths from 1000 mm to 3500 mm. Thickness options typically range from 4 mm up to 100 mm, with lengths between 2000 mm and 6000 mm. Custom sizes can also be supplied to meet specific project requirements.
