Stainless Steel Plates for Non-metallic Mineral Products (Cement/ Glass/ Ceramic): 310S/2535Nb Selection and 4 Item Lists
In the non-metallic mineral products (cement/glass/ceramic) we have organized four stainless steel parts: commonly used 310S / 2535Nb / 304, with thickness ranging from 4–60 mm.
4 parts and list of selected materials
| Part / Component | Recommended grade | Specification / Thickness | Surface | Main Failure Modes | Reference Standards |
|---|---|---|---|---|---|
| Clinker Cooler Grate/Chain Sintering Machine Grates | 2535Nb（ZG40Cr25Ni20Si2）/310S/ZG0Cr25Ni20 | 15–40mm thick | Cast Face/Grooved Face | 1100–1200℃ load + kiln dust corrosion + rapid cooling and heating low cycle fatigue; failure case at 750℃, thickness of 15mm reduced to less than 10mm causing cracking | GB/T 8492；GB/T 3280 |
| Glass Melting Kiln Rolls/Radiant Tubes | 310S/314/Heat Resistant Castings | Roll wall 8–30mm | Centrifugal Casting/Grooved Face | High temperature oxidation + glass melt erosion + thermal cycling cracking | GB/T 8492；GB/T 3280 |
| Ceramic Kiln Rolls/Bonding Materials | 310S/Heat Resistant Stainless Steel | Rolls φ20–60mm | Grooved Face/2B | Thermal creep bending + thermal shock + glaze erosion | GB/T 3280, JC/T Ceramic Mechanical Standards |
| Cement Screw Conveyor, Cement Screw Separator | 304Wear-resistant Welding | Blades 4-12mm | 2B/Overlay | Cement Mill Corrosion + Alkaline Corrosion | GB/T 3280 |

Most common grades in this industry are 310S (3), 2535Nb (1), and 304 (1) —— numbers in parentheses indicate the number of affected areas, useful for quoting and material ordering.
- Key points
- At high temperatures, consider thermal fatigue and oxidation; if necessary, use 310S / heat-resistant castings (3/4 items hit).
- Thickness range: 4–60 mm —— thin plates are mostly formed parts (consider bending rebound and deep drawing cracking), thick plates are mostly welded structures (consider heat input and sensitization).
Common issues
Which stainless steel is used most in the non-metallic mineral products industry (cement, glass, ceramics)?
Based on these 4 areas, the most common grade is 310S (3 items), followed by 2535Nb (1 item) and 304 (1 item). Specific to a part depends on the medium and temperature; for example, stainless steel countertops that come into contact with salt water should switch from 304 to 316L.
What's the most vulnerable part?
By failure description, typical is "Clinker Cooler Grate/Chain Clinker Cooler Grate": 1100–1200℃ load + kiln dust erosion + rapid cooling and heating low cycle fatigue; failure case at 750℃, thickness of 15mm reduced to less than 10mm before cracking. Recommended grade 2535Nb (ZG40Cr25Ni20Si2)/310S/ZG0Cr25Ni20, thickness 15–40mm. For this condition, it's recommended to clarify medium concentration, temperature, and cleaning method in the design phase.
What thickness should I choose?
The thickness range on the list is 4–60 mm. Thin plates consider forming and surface quality, thick plates consider welding and structural strength; different manufacturers may have different values for the same part, review your drawings or conditions to confirm.
