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.
| Buyer Question | Answer |
|---|---|
| Is 347 niobium stabilized? | Yes. |
| Is 347 the same as 347H? | No. |
| Can it be used in refineries? | It is used in relevant refinery applications. |
| Can custom angles be supplied? | Yes. |
| Is hot-rolled stock always available? | No. |
| Can it be plate formed? | Yes. |
| Can PMI be supplied? | Yes. |
| Is third-party inspection available? | Yes. |
| Can it be welded? | Yes, with appropriate procedures. |
| What must be confirmed for high-temperature use? | Temperature, code, load, atmosphere and grade condition. |
Provide the refinery service, design temperature, code, 347 or 347H requirement, section drawing, welding and NDT scope, quantity and certificate. Shangyou will separate parent-plate compliance from finished-profile inspection in the quotation. | REQUEST A QUOTE · SEND SIZE LIST OR DRAWING
