Product Details, Applications & Buyer Guidance
347 is often selected for components exposed to intermittent heating, refinery service and welded assemblies where stabilized chemistry is required.
Applications include refinery supports, expansion joints, exhaust systems, chemical equipment, high-temperature brackets and furnace auxiliaries.
Type 347 and 347H must not be treated as interchangeable. High-temperature code calculations may require the H grade, specific heat treatment and defined mechanical properties.
Special-grade angles may be fabricated from certified plate. Parent-plate certification and finished-profile inspection should be clearly separated in the purchase order.
