904L stainless steel plates are widely used in industries such as chemical processing, marine engineering, and pharmaceuticals due to their excellent corrosion resistance and mechanical properties. As a professional supplier of 904L stainless steel plates, Ronsco offers rich inventory and comprehensive services, providing customers with high-quality 904L plate solutions. This article, based on the Ronsco official website and its 904L stainless steel plate product page, deeply analyzes common problems encountered when using 904L stainless steel plates and provides effective countermeasures to help businesses select and use 904L materials more efficiently.
1. Corrosion Resistance of 904L Stainless Steel Plates and Common Corrosion Issues
904L stainless steel contains 23–28% chromium, 19–23% nickel, and 4.5% molybdenum, offering excellent resistance to pitting and intergranular corrosion (with a Pitting Resistance Equivalent Number, PREN, of about 35). It is an ideal choice for marine and chemical environments. However, if surface treatment is insufficient, localized corrosion may still occur in actual applications.
Recommended Solutions:
-
Use professional pickling and passivation processes to ensure the surface is free of oxides and contaminants.
-
Conduct regular maintenance and cleaning to prevent salt and chemical deposits.
-
Perform solution annealing after welding to avoid intergranular corrosion.

2. Processing Challenges and Efficient Machining Tips
Due to its high nickel content, 904L stainless steel plates have a hardness above 490 MPa, making cutting and welding more difficult. Using conventional equipment and processes can reduce machining efficiency and increase material waste.
Machining Recommendations:
-
Use high-speed steel or carbide tools, reduce cutting speeds, and extend tool life.
-
For welding, select ERNiCrMo-3 filler material to ensure weld corrosion resistance and strength.
-
When necessary, conduct intermediate annealing to reduce the risk of cracking caused by work hardening.

3. Deformation and Crack Prevention for 904L Stainless Steel Plates
Improper control during thermal processing or welding can cause local deformation and cracks, affecting product quality and service life.
Prevention Measures:
-
Control welding heat input and use multi-pass welding.
-
Apply preheating and post-weld heat treatment to relieve internal stress.
-
Use Ronsco’s standardized cold-rolled or hot-rolled plates for better stability.
4. How to Scientifically Select 904L Stainless Steel Plate Specifications?
Improper choice of plate thickness or size can directly affect project costs and performance. Ronsco offers 904L stainless steel plates with thicknesses ranging from 3mm to 60mm and widths exceeding 2000mm to meet diverse engineering needs.
Material Selection Tips:
-
Choose thickness and dimensions according to operating conditions.
-
Prioritize high-quality materials certified by ISO and ASTM.
-
Leverage Ronsco’s professional technical support to customize solutions.
