347 Stainless Steel

What Does 347 Stainless Steel Mean?

Type 347 stainless steel is a specific type of austenitic stainless steel, which imparts excellent corrosion resistance properties. Type 347 stainless steel is stabilized with columbium, which allows it to avoid intergranular corrosion when heated to its sensitization temperature range.

Corrosionpedia Explains 347 Stainless Steel

Type 347 is designed to have properties similar to type 304 stainless steel, which is the most common grade of austenitic stainless steel.

The most notable difference is its ability to resist intergranular corrosion. This resistance to intergranular corrosion makes type 347 particularly well suited for welding applications. Since welding heats austenitic stainless steel into and above its sensitization temperature range, intergranular corrosion can be a concern.

Type 347 is also commonly used for making fasteners. It can be found in many industries such as oil and gas and aerospace.
