Introduction of High Manganese Steel Impact Plates?
High manganese steel impact plates (also called impact liners or impact aprons) are protective components installed inside an impact crusher. Their primary purpose is to absorb crushing force and prevent damage to the crusher body.
High manganese steel is widely used because of its unique characteristics:
Work-hardening ability
High toughness
Excellent resistance to impact loading
Long service life in abrasive environments
With continuous impact from stone and ore, manganese steel becomes harder during operation, making it one of the most reliable materials for heavy-duty impact crusher applications.
Material Grades We Offer
We manufacture impact plates using several premium manganese grades to match different working conditions:
Mn13 / ZGMn13 – High toughness, suitable for general crushing
Mn13Cr2 – Better wear resistance, ideal for medium-hard stone
Mn18 / Mn18Cr2 – Industry standard, excellent for high-impact applications
Mn22 / Mn22Cr2 – Superior for extremely abrasive and high-energy crushing
Our metallurgical control ensures stable chemical composition, fine grain structure, and excellent hardening performance.
Key Features of Our High Manganese Steel Impact Plates
1. Work-Hardening Performance
Under repeated impact and compression, manganese steel surface hardness increases from 200HB to over 550HB, dramatically extending the working life.
2. Heavy-Duty Structural Design
Our impact plates are engineered with:
Reinforced rib structure
Precision casting
Extra thickness design for extended durability
These ensure the plates withstand high-energy impacts without cracking.
3. Precision Machined for Perfect Fit
Tolerance is controlled within ±1mm, ensuring compatibility with major crusher brands and stable installation.
4. Superior Metallurgical Quality
We use vacuum casting, strict heat treatment, and controlled cooling to ensure maximum hardness, impact resistance, and consistency.
5. Customizable Designs
We support OEM & ODM production according to customer drawings, samples, or specifications.
Applications of High Manganese Steel Impact Plates
Our impact plates are widely used in:
Stone quarries
Mining plants
Cement production lines
Aggregate manufacturing
Construction waste recycling
Limestone and granite crushing
Metallurgical industries
Wherever there is a need for impact crushing, high manganese steel impact plates play a vital role.
Why Choose High Manganese Steel for Impact Plates?
High manganese steel remains the most widely used material for impact crusher wear parts due to its unique mechanical properties:
Strong hardening ability
High elongation rate (up to 40%)
Excellent crack resistance
Superior wear resistance under high-stress impact
Unlike alloy steel or chrome steel, manganese steel becomes tougher the more it is shocked—making it ideal for impact plates.
