High Manganese Steel Impact Plate for PF & PFW Impact Crusher
Heavy-Duty Impact Apron Liners | Mn13Cr2 & Mn18Cr2 Alloy | High Impact Toughness | 20-Ton Container Load MOQ
Hengtai's heavy-duty high manganese steel impact plates (also known as impact aprons or liner plates) are specifically engineered for installation inside the high-velocity crushing cavity of industrial impact crushers. As a leading specialized heavy casting foundry, we provide 100% interchangeable replacement wear liners that safeguard your equipment shell while maximizing rock reduction efficiency.
Under severe and continuous high-speed stone collision, our manganese formulation work-hardens rapidly, ensuring the impact plates remain exceptionally tough without risk of fracturing or cracking. We focus strictly on 20GP container-load B2B bulk orders to provide international mining networks and aggregate plants with factory-direct pricing advantages.

Working Principle & Dynamic Cavity Protection
Secondary Crushing Impact Boundary: In an impact crusher, the blow bars on the high-speed rotor fling the feed rock violently against the impact plates hanging in the upper and lower crushing cavities. The impact liner acts as the primary anvil where massive kinetic energy is rebounded into structural rock fracturing.
Advanced Deformation Hardening: Our specialized high manganese matrix alloy (Mn13Cr2 / Mn18Cr2) undergoes rapid localized crystal transformation upon receiving high-impact stone shocks, drastically climbing in hardness while the core retains its original superior ductility.
Anti-Flowing Chrome Integration: By adding 1.5% - 2.5% Chromium (Cr) to our matrix formula, Hengtai significantly enhances the yield strength of the liner. This structurally prevents plastic deformation or expansion over months of continuous compression, protecting the machinery's bolted housing.

Frequently Asked Questions
Our 20-ton MOQ is curated specifically for B2B wholesale buyers, aggregate distributors, and mining corporations. Since high-manganese casting blocks are heavy-duty components, a 20-ton order perfectly fills a 20GP container load. This completely minimizes ocean freight costs per ton and streamlines shipping logistics, allowing us to pass the maximum manufacturing savings directly to you.
Due to ongoing market price fluctuations for raw steel, manganese, and chromium alloys, we do not issue fixed pricing online. Please send your required crusher series model numbers, custom blueprints/drawings, or OEM original part numbers to our sales engineers through WhatsApp or Email. We supply updated, volume-based factory-direct quotes in real time.
