904L Stainless Steel Seamless Pipe: The Complete Guide
904L stainless steel seamless pipe is a super austenitic stainless steel seamless pipe with good features.
Therefore, at any given time, you must choose high quality and reliable 904L stainless steel seamless pipe.
To do that, you must consider the applications, specifications, surface treatment, production process, etc.
The best part?
You will learn all that in this 904L stainless steel seamless pipe guide.
So, let’s get straight to the main subject of this guide.
What is a 904L Stainless Steel Seamless Pipe
904L stainless steel seamless pipe, commonly known as ASTM B677 UNS N08904 pipe, is an austenitic stainless steel with better corrosion resistance.
It also has excellent corrosion resistance to reducing acids such as sulfuric acid and phosphoric acid due to the addition of 1.5% copper content.
In addition, it has low carbon properties for welding applications.
904L Stainless Steel Seamless Pipe Applications
904L stainless steel seamless pipes are used in many fields, such as:
- Petrochemical equipment, reactor
- Heat exchanger
- Power plant flue gas desulfurization device
- Organic acid treatment system
- Sea water heat exchanger
- Paper industry equipment
- Pharmaceutical industry and other chemical equipment
- Pressure vessel
- Food equipment
- Condenser tubes
- Control and instrumentation systems
In many of the above applications, even ordinary stainless steel 304 seamless pipe is cheaper. But in special fields, special duplex 904L stainless steel is indispensable and irreplaceable.
In recent years, with the rapid development of the economy and the continuous improvement of the level of the industrial field, more and more projects have chosen 904L stainless steel seamless pipes for use.
