Both SS 347 and SS 347H, belonging to the austenitic stainless steel family, offer similar attributes with the primary distinction lying in their carbon content. SS 347H Welded Tubing, featuring a higher carbon content compared to Stainless Steel 347 Tubes, stands out for its enhanced toughness. These alloys, stabilized by the addition of columbium, exhibit remarkable resistance in strongly oxidizing environments and maintain their integrity even at elevated temperatures ranging from approximately 427 to 816 degrees Celsius.
