Stainless Steel Sheets for Waste Resource Utilization Industry: 316L/S21800 Selection and 3 Item Lists
In the waste resource utilization industry, we have organized three parts using stainless steel: commonly used 316L / S21800 / 904L, with thickness ranging from 3–50 mm.
Three parts and material lists
| Part / Component | Recommended Grade | Specifications / Thickness | Surface | Main Failure Modes | Reference Standards |
|---|---|---|---|---|---|
| Crusher Screen/Brake Liners for Scrap Steel/Alloys | S21800/Dual-phase steel/Manganese steel | 10–40mm | Cast/Forged/Glazed Welding | High-impact wear + corrosion | ASTM A276；GB/T 3280 |
| Waste Batteries/Electronic Waste Leaching Vessel/Piping | 316L/904L/254SMO | 3–12mm | 2B/Acid washing | Acid/Basal leaching + heavy metals + Cl⁻ | ASTM A240；GB/T 3280 |
| Grate/Flue Gas Pipes for Incinerators | 310S/Heat-resistant castings/316L | 10–50mm | Cast surface/2B | High temperature + chloride corrosion + wear | GB/T 8492；GB/T 3280 |
Table listsStandard Configurations.A single part may require different grades (e.g., 304 to 316L or 2205) depending on the medium, temperature, and welding method. Be clear about the usage conditions; specifying grades directly can be more convenient.
Material Selection Tips
- Common Grades in This Industry: 316L (2), S21800 (1), 904L (1) —— Parentheses indicate the number of affected areas, useful for quoting and material preparation.
- Corrosion Sources: Chlorides and salts (pitting, crevice corrosion) (2/3 hits).
- Wear Parts (edges, liners, conveying parts) require hardness consideration, not just corrosion resistance (2/3 hits).
- Thickness range 3–50 mm: Thin plates are mostly formed parts (considering bend rebound and deep drawing cracking), thick plates are mostly welded structures (considering heat input and sensitization).
Frequently Asked Questions
What stainless steel is used most in the recycling industry?
By total pages, the top 3 are: 316L (2), S21800 (1), and 904L (1). For specific parts, consult media and temperature, e.g., stainless countertops require switching from 304 to 316L when exposed to saltwater.
What parts are the easiest to fail?
By failure description, typical is "spent batteries/ electronic waste leaching tank/pipes": acid/base leaching + metals + Cl⁻; recommended grades 316L/904L/254SMO, size 3–12mm. For this condition, specify media concentration, temperature, and cleaning method in the design phase.
What thickness should I choose?
Thickness ranges from 3–50 mm. Thin plates consider forming and surface quality, thick plates consider welding and structural strength; different manufacturers may have varying values for the same part based on your drawings or operating conditions. Recheck as needed.
