Material Selection for Every Wear Part
The product catalog shows available grades and part options. This page explains how geometry, feed material, impact conditions, and heat-treatment requirements are reviewed before a material grade is selected.

We Work With Your Team, Not Just For Your Order
Our application engineers and technical sales representatives review the equipment, the feed material and operating conditions, and the wear pattern before recommending a replacement part.
Listen to the Operators
Our engineers review your equipment, feed material, and wear history, and discuss the findings directly with your maintenance team.
Analyse the machine and material
We analyze the operating conditions and material behavior, including wear patterns on worn surfaces and the actual loads carried by the part.
Redesign and replace
We can redesign the original part and supply a replacement to help extend service life and reduce changeover downtime.
Customization Options
Customization extends beyond branding and nameplates. Geometry, alloy chemistry, and feed material are reviewed together to ensure the part is matched to the actual operating conditions.
Geometry
- Weight and profile
- Pin bore diameter
- Mounting pattern
- Machining tolerance
Material
- Alloy grade
- Target hardness
- Heat-treatment process
- Impact toughness
Discharge
- Grid opening size
- Opening shape
- Discharge angle
- Grid arrangement
Grades We Cast
Hardness ranges and applications shown are indicative only. The final grade is selected based on your feed material, impact conditions, and target wear life.
| Material | Indicative hardness | Typical application | Note |
|---|---|---|---|
| Austenitic High Manganese Steel | HB 180–230 (work hardening) | Hammers, grids, liners under heavy impact | Work hardens in service; suited to high-impact feed. |
| High Chrome Alloy Cast Iron | HRC 58–62 | Abrasion-dominant wear surfaces | High abrasion resistance; impact load should be controlled. |
| High Strength Martensitic Cast Steel | HRC 45–52 | Hammers, rotor caps, anvil and wear plates | Balances hardness with toughness for mixed feed. |
| Chrome Molybdenum Alloy Steel | HB 300–380 | Hammer pins, rotor caps, grids, reject door | Good strength and fatigue resistance under shock. |
| Heat Resistant Stainless Steel | HB 180–240 | Hot zones and special service conditions | Selected where temperature or corrosion is a factor. |
| Carbon Steel | HB 140–200 | Large structural parts, common parts and fabricated assemblies | Weldable construction for frames and chutes. |
Custom Technical Specifications or Upgraded Version
We specialize in the manufacture of shredder parts and components. We have supplied OEM parts to several established shredder manufacturers under confidentiality agreements, so we cannot disclose their names. This experience has given us a working knowledge of the quality standards and technical specifications these OEMs require. We can manufacture either to your drawings and specifications or to an optimized design that we finalize after reviewing your operating conditions.
Customized Specification
- Geometry, weight, and fit engineered for correct assembly
- Compatibility with existing machine settings and assembly procedures
- Suitability for recurring orders and ongoing consumable supply
- Inspection records aligned with the agreed specification
Performance Upgrades
- Propose alternative alloy chemistry or a heat-treatment process
- Adjust the profile after reviewing worn parts and feed material
- Extended service life and reduced changeover downtime
- Trial batch with complete test data
Not Sure Which Grade Suits Your Feed Material?
Send the shredder model, the feed material, and a photo of a worn part. We will recommend a material grade and explain the reasoning.
