Product Description:
This 347H stainless steel angle bar meets ASTM A276 standards, available in 50x50x5mm and 75x75x8mm sizes for petrochemical refinery high-temperature service. The niobium stabilization prevents intergranular corrosion after high-temperature exposure, while the high carbon content (H grade) provides superior creep and rupture strength for service up to 900°C. Typical applications include petroleum refinery structural supports, catalytic cracker framework, high-temperature process structures, furnace supports, heat exchanger framing, chemical plant high-temperature sections, and any refinery or petrochemical structure requiring resistance to intergranular attack at elevated temperatures.
