Stainless Steel Plates for Tobacco Industry: 316L/304 Selection and List of Four Parts

In the tobacco industry, we have organized four parts using stainless steel: commonly used 316L / 304 / 420, with thickness ranging from 1–8 mm.

Key Considerations

  • The most common grades in this industry are 316L (3), 304 (2), and 420 (1). The numbers in parentheses indicate how many parts they apply to, useful for quoting and material procurement.
  • High-temperature sections also face hot fatigue and oxidation. Necessary: 310S / heat-resistant castings (3/4 items hit).
  • Wear components like cutting edges, liners, and conveying pieces need hardness considerations, not just corrosion resistance (3/4 items hit).
  • Thickness range 1–8 mm: Thin plates are formed parts (consider bending rebound and deep drawing cracks), thick plates are welded structures (consider heat input and sensitization).

Common Issues

Which stainless steel is used most in the tobacco industry?
Based on total pages, 316L (3), 304 (2), and 420 (1) appear most frequently. Specific to a part depends on medium and temperature; for example, stainless countertops exposed to salt water should switch from 304 to 316L.
What parts are prone to failure?
Based on failures, typical is "curing/air-drying drum": steam + humidity + leaf wear + fragrance corrosion. Recommended grade: 304/316L, size 2–6mm. For this condition, specify medium concentration, temperature, and cleaning methods in the design phase.
How thick should plates be?
Thickness range is 1–8 mm. Thin plates consider forming and surface quality; thick plates look at welding strength and structural integrity. Different manufacturers may choose different values based on your drawings or operating conditions.
