FerroMax®
Strong and durable
FerroMax®: Designed for extreme mining environments to reduce frequent changes and costly downtime.
FerroMax®: Designed for extreme mining environments to reduce frequent changes and costly downtime.
Low-carbon steel screens fail rapidly in mining environments, creating operational and financial burdens.
65Mn low-carbon steel screens develop red rust within 48–72 hours, creating a cascade of operational issues and financial losses for mining operations.
"We were forced to shut down the machine twice a month to replace the screens. The labor cost for screen replacement alone was ≥$2,800/month."
The true cost of 65Mn steel corrosion extends far beyond replacement parts.
For 65Mn steel of the same specification in an environment with 40°C, 75% RH, and Cl⁻-containing dust:
If the mesh aperture is enlarged by 20%, the screening efficiency will suddenly drop by 30%.
Corrosion pits combined with vibration reduce fatigue limits by 60%, leading to a 15% annual risk of sudden fracture.
Each downtime loss is ≥$7,000, with an annual hidden cost exceeding $140,000.
Engineered for Extreme Mining Environments to Eliminate Corrosion Issues
FerroMax® screens outperform conventional 65Mn steel in all critical performance metrics, delivering exceptional durability in harsh mining environments.
| PERFORMANCE METRIC | 65Mn STEEL | FERROMAX® SERIES |
|---|---|---|
| Indoor storage anti-rust period | 10–15 days | ≥ 365 days |
| Actual anti-rust period in mines | 5–10 days | 3–6 months |
| Annual corrosion rate | 0.39–0.65 mm | ≤ 0.05 mm |
| Fatigue life | 1.2×10⁶ cycles | ≥ 4.5×10⁶ cycles |
| Annual replacement frequency | 12–24 times | 4–6 times |
"Since implementing FerroMax® screens, our downtime has decreased by 75%, saving us over $200,000 annually."

Our proprietary technology combines advanced materials science with innovative engineering.
① 30-40μm UV-resistant hard film, QUV aging ≥500h
② Rainwater erosion resistance (film thickness loss ≤10% after 1h of erosion)
③ Solvent-free, VOC=0, ROHS certified
65Mn, quenched & twice isothermal-drawn, achieving a tensile strength of 1600–1800 MPa. The coating forms a metallurgical bond with the substrate, resisting impact and preventing peeling.
Patented "double-lock" weaving nodes reduce the stress concentration factor from 3.0 to 1.4, lowering the probability of fatigue crack initiation by 60%.
FerroMax® has passed rigorous 1000-hour salt spray testing, confirming its superior corrosion resistance. The unique combination of materials and manufacturing processes delivers 275% longer fatigue life compared to #55 steel.
"FerroMax® screens demonstrated exceptional performance in our accelerated corrosion testing, outperforming all conventional alternatives."
Saving $25,000 per year per screening machine
The economic benefits of FerroMax® extend beyond reduced replacement frequency, impacting multiple cost centers in your operation.
PRODUCTION LINE SAVINGS
An entire production line with 8 machines can save approximately $200,000 annually
