Stainless Steel 347/347H Wire Rods are high-performance stainless steel products widely used across industrial fabrication, structural engineering, and high-temperature processing environments. These wire rods are designed to deliver superior strength, stability, and corrosion resistance in demanding conditions such as chemical processing plants, pressure equipment manufacturing, power generation facilities, and heavy engineering industries. Steel Icon Stainless Pvt. Ltd. manufactures precision-engineered Stainless Steel 347/347H Wire Rods that meet global quality expectations while supporting modern industrial applications that require reliability and long service life.
Industries involved in petrochemicals, oil and gas, heat exchangers, pressure vessels, and fabrication rely on stabilized stainless steel grades to maintain structural integrity under stress and elevated temperatures. Stainless Steel 347/347H Wire Rods are particularly valuable where resistance to intergranular corrosion and carbide precipitation is essential. Their metallurgical stability makes them suitable for components that experience prolonged thermal exposure during welding or operational processes. As industrial infrastructure continues to expand globally, demand for these specialized stainless steel wire rods continues to grow across manufacturing and engineering sectors.
Stainless Steel 347 and 347H are austenitic chromium-nickel stainless steel grades stabilized with niobium. The addition of niobium helps prevent chromium carbide precipitation during welding and high-temperature exposure, improving resistance to intergranular corrosion. Stainless Steel 347 Wire Rods typically contain controlled amounts of chromium, nickel, and niobium, which together provide excellent oxidation resistance, high tensile strength, and long-term metallurgical stability.
The 347H grade is a high-carbon variation designed specifically for elevated temperature applications. The higher carbon content increases creep strength and makes it suitable for heat-resistant structural components used in boilers, superheaters, and power plant equipment. Stainless Steel 347/347H Wire Rods maintain good ductility and toughness while offering excellent resistance to oxidation in temperatures approaching 870°C in intermittent service.
From a manufacturing perspective, these wire rods exhibit excellent formability, weldability, and machinability, allowing them to be processed into fasteners, springs, wire forms, and fabricated components used in industrial assemblies. Their austenitic microstructure ensures consistent performance even under cyclic thermal loading conditions.

Stainless Steel 347/347H Wire Rods provide a combination of strength, durability, and corrosion resistance that supports long-term industrial performance. Their stabilized composition minimizes the risk of sensitization during welding, which helps preserve corrosion resistance in heat-affected zones. This property is particularly valuable in fabrication projects involving pressure equipment and high-temperature systems.
Another major advantage is their ability to perform reliably in environments where oxidation resistance and thermal stability are critical. Components produced from these wire rods maintain mechanical strength even after extended exposure to high temperatures. This makes them suitable for industrial environments such as refineries, chemical plants, and thermal processing equipment.
Durability is another important benefit. Stainless Steel 347/347H Wire Rods are resistant to scaling, corrosion, and mechanical wear, which helps reduce maintenance costs and improve operational efficiency. Their machinability and formability allow manufacturers to create precision-engineered components while maintaining cost-effective production processes.
