904l stainless steel vs 316l : which is better?

In summary:

– 904L stainless steel has exceptional corrosion resistance, especially in aggressive environments, and is commonly used in chemical processing, offshore oil and gas, and seawater applications.

– 316L stainless steel provides good corrosion resistance but may not be as resistant to aggressive environments as 904L.

– 904L stainless steel has a higher nickel and molybdenum content than 316L, enhancing its corrosion resistance.

– 316L stainless steel has good mechanical properties and is versatile and cost-effective.

– 904L stainless steel is more specialized, may have limited availability, and is generally more expensive compared to 316L.

How to weld 904l stainless steel?
  1. Use a filler material specifically designed for welding 904L stainless steel.
  2. Clean the base metal thoroughly before welding.
  3. Control heat input and interpass temperature to avoid overheating and carbide precipitation.
  4. Employ low heat input welding techniques like TIG or plasma arc welding.
  5. Use an inert shielding gas, such as argon, during welding.
  6. Consider post-weld heat treatment if required.
  7. Conduct tests and inspections to ensure weld quality.

Remember to consult welding codes, standards, and specific procedures provided by the manufacturer for detailed instructions and best practices when welding 904L stainless steel. Engage an experienced welder familiar with high-alloy stainless steels for proper execution.
