Stainless steel 347 is a specialized grade of austenitic stainless steel that has carved a strong reputation in industries requiring both heat resistance and long-term durability. Unlike standard grades, it is stabilized with niobium, which enhances its ability to resist carbide precipitation, especially in high-temperature environments. This stability makes it a material of choice for operations where prolonged exposure to heat is unavoidable.

What sets stainless steel 347 apart is its exceptional ability to perform under conditions that would cause many alloys to weaken or corrode. It is engineered to withstand temperatures up to 870°C in continuous service and 925°C in intermittent service, making it suitable for thermal-intensive applications. In industries where equipment is exposed to cyclic heating, oxidation resistance becomes vital, and stainless steel 347 consistently delivers reliable results.

Here is an infographic showing 8 key insights you should know about stainless steel 347 for industrial use.
