904L Stainless Steel Sheet for Chemical Storage Tanks in Indonesia

This requirement called for 904L stainless steel sheet for chemical storage-tank fabrication. The alloy was considered because its high nickel, chromium and molybdenum content can improve performance in selected acidic and chloride environments compared with common 300-series grades. Actual suitability remained dependent on the stored chemical and operating conditions.

The buyer needed a controlled grade for tank shells and fabricated parts. Risks included substituting visually similar stainless steel, failing to retain traceability after cutting and selecting 904L without fully defining chemical concentration, temperature, aeration and contamination.

• Reviewed the chemical medium and requested concentration and temperature data.
• Confirmed UNS N08904 and the correct plate/sheet standard.
• Arranged PMI and maintained heat-number linkage.
• Controlled cut sizes and protected surfaces for fabrication.
• Prepared certificate and packing records according to the agreed inspection plan.
  

  

  

Add verified welding/fabrication feedback, document acceptance and arrival condition.

904L is not a universal substitute for nickel alloys. Strong reducing acids, high temperatures, chloride concentration, crevices and oxidizing contaminants can change alloy performance. Corrosion data or specialist review may be required.

Send the chemical, concentration, temperature, tank design code, sheet dimensions, welding process, quantity and required inspection documents.
