Stainless Steel Plates for the Tobacco Industry: 316L/304 Selection and Four-Part List
In the tobacco industry, we have identified four parts made of stainless steel: commonly used grades 316L / 304 / 420, with thickness ranging from 1–8 mm.
Four parts and material list
| Part / Component | Recommended grade | Size / Thickness | Surface | High failure modes | Reference standards |
|---|---|---|---|---|---|
| Curing/Drying Trommel for Tobacco Leaves | 304/316L | 2–6mm | 2B/Ra≤0.8μm | Steam + Humidity + Tobacco Wear + Fragrance Corrosion | GB/T 3280; YC/T Mechanical Standards |
| Slicer Blade/Spindle | 420/440C | Blade 3-8mm | Quench Hardened + Polished | High hardness wear and chipping | GB/T 1220; YC/T Slicer Standards |
| Rolamite Gun/Curing Components | 304/316L | 1–3mm | Mirror / 2B | Tobacco Wear + Fragrance + Cleaner | GB/T 3280; YC/T ROLAMITE Standards |
| Expanding Equipment Pipes for Tobacco Stalks | 316L | 2–6mm | 2B | High Temperature Steam + Medium Corrosion | GB/T 3280 |
Table showsStandard Configurations.Different parts may require 316L, 304, or 2205 depending on the medium, temperature, and welding method. Clarifying usage conditions saves time compared with specifying grades directly.
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, which is useful for quoting and material procurement.
- High-temperature sections also face hot fatigue and oxidation. Essential: 310S / heat-resistant castings (applicable to 3 of 4 items).
- Wear components such as cutting edges, liners, and conveying parts require hardness considerations, not just corrosion resistance (applicable to 3 of 4 items).
- Thickness range 1–8 mm: thin plates are formed parts (consider bending springback 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. The specific choice for a part depends on medium and temperature; for example, stainless steel worktops exposed to salt water should switch from 304 to 316L.
Which parts are prone to failure?
Based on failure data, a typical case is the "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 during the design phase.
How thick should plates be?
Thickness range is 1–8 mm. Thin plates require consideration of forming and surface quality; thick plates require attention to welding strength and structural integrity. Different manufacturers may choose different values based on your drawings or operating conditions.
