Frequently Asked Questions
Mn13 is a standard grade ideal for general crushing with excellent impact resistance. Mn18 is a premium grade with higher manganese content, providing enhanced wear resistance for highly abrasive materials like basalt or granite.
High-Chromium plates (Cr26/Cr28) should be used when abrasion is the primary wear mechanism, especially with silica-rich materials. Manganese steel is better suited for applications requiring high impact absorption.
It uses a vacuum casting process to bond a high-chromium wear surface (for hardness) to a manganese steel base (for toughness), offering a lifespan 2-3x longer than standard single-material plates.
Yes. While primarily for jaw crushers, we provide specialized concave/mantle designs for cone crushers and reinforced alloy combinations specifically for hammer crusher impact applications.
We employ a multi-stage QC process including spectrometer material verification for chemistry, ultrasonic testing to find internal defects, and precise dimensional inspection.
By extending the service life (up to 150% longer) and implementing faster change-out designs, you reduce both the frequency of part purchases and the costly downtime of your production line.
