Stainless Steel 347H Pipes and Tubes Manufacturer

347H stainless steel tubing is a high carbon (0.04 - 0.10) version of the alloy. It was developed for enhanced creep resistance and high strength at temperatures above 1000°F (537°C). In most cases, the carbon content of the pipe makes for dual certification. 347H stainless steel pipe is a stable stainless steel sheet whose main advantage is that it provides good resistance to intergranular corrosion over the temperature range of chromium carbide precipitation, from 800 to 1500°F (427 to 816°C). Alloy 347 stainless steel sheet is stabilized by the addition of niobium and tantalum.

The steel has excellent forming and welding qualities, and excellent toughness even at low temperatures.
