Stainless steel 904l pipe

Stainless steel 904l pipe specification

What is a 904l stainless steel pipe/ tube?

This low-carbon iron alloy is a superaustenitic steels (with pren over 40) renowned and coveted for its excellent corrosion resistance. A 904l stainless steel pipe is ubiquitous in chemical processing, condenser tubes, oil and gas sectors, seawater applications, air pollution control, and pharmaceuticals.

What are the unique properties of 904l tubing that make it suitable for use in harsh environments?

The two hallmarks of this material are superior corrosion tolerance and suitability for service temperatures up to 450°c. 904l ERW pipe contain chromium, nickel, molybdenum and copper to ramp up corrosion resistance. For instance, SS 904l tubes can tolerate dilute sulphuric acid in pickling equipment.
