Material Selection Behind Every Wear Part
Published product records show what is available. This page explains how geometry, feed material, impact condition and heat treatment are reviewed before a grade is selected.

We Work With Your Team, Not Only For Your Order
Our engineers and sales representatives study the machine, the material working condition and the worn surface before proposing a replacement part.
Listen to the operation
Engineers review your machine, feed and wear history, and discuss the problem directly with your maintenance team.
Analyse machine and material
Working condition and material behaviour are analysed, including worn surfaces and the loads the part actually carries.
Redesign and replace
The original part can be redesigned and substituted to help extend wear life and reduce change-out stops.
What Can Be Adjusted
Customisation is not limited to a logo or a nameplate. Geometry, chemistry and circuit settings are reviewed together so the part fits the actual operating condition.
Geometry
- Weight and profile
- Pin bore size
- Fixing pattern
- Machining tolerance
Material
- Alloy grade
- Hardness target
- Heat treatment route
- Impact toughness
Circuit
- Grid hole size
- Hole shape
- Discharge angle
- Liner position
Grades We Cast
Indicative hardness ranges and typical applications. The final grade is confirmed against your feed material, impact condition and target wear behaviour.
| 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, grids, anvil and wall plates | Balances hardness with toughness for mixed feed. |
| Chrome Molybdenum Alloy Steel | HB 300–380 | Hammer pins, rotor caps, structural parts | 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 and fabricated assemblies | Weldable construction for frames and chutes. |
OEM Specification or Upgraded Version
As a direct supplier to several mainstream shredder brands, we produce parts to the original specification or to an improved version agreed after reviewing your working condition.
OEM Specification
- Geometry, weight and fit identical to the original part
- No change needed to machine settings or assembly
- Suitable for repeat consumable supply
- Inspection records matched to the original requirement
Performance Upgraded
- Alternative chemistry or heat treatment route proposed
- Profile adjusted after review of worn parts and feed
- Aims to help extend wear life and reduce change-out stops
- Trial batch supported with full test data
Not sure which grade fits your feed?
Send the machine model, the material you shred and a photo of a worn part. We will propose a grade with the reasoning behind it.
