Product Description

Product Description

Material Summary

Type 347H is a high carbon austenitic chromium stainless steel. Found in applications that demand high temperature resistance, other major design features include:
1. Similar resistance and corrosion protection as 304
2. Used for heavy welded equipment when annealing is not possible.
3. Good oxidation resistance, on par with most other austenitic stainless steels
4. Higher carbon allows for better high temperature creep properties.

The "H" in 347H stands for "high carbon" content. This variety of stainless steel has higher amounts of carbon than standard 347 stainless steel, with increased tensile strength and creep resistance at elevated temperatures. Due to its higher carbon content, this type of stainless steel provides better stress rupture properties than the standard version. It also offers excellent resistance to oxidation in intermittent service up to 1600F and continuous service up to 1700 degrees F.

Both steels are non-magnetic and can be used in applications where magnetism is a concern.
347h is more expensive than 347 due to its higher carbon content.
Applications for both steels include aerospace, chemical processing, oil and gas, and power generation.
