Finished wear parts / GOREX 400—500
Hardness at the core. Evidence in every delivery.
GOREX is our family of finished wear parts and cut-to-requirement wear components for construction, recycling, mining and material handling. Every quoted class is tied to documented source steel, the actual producing mill and order-specific inspection requirements.

One impact-abrasion study / test-specific
A measured signal—not a wear-life promise
Under the cited HBIS/Tangsteel test conditions, the tested NM500 steel recorded 8.3 times the wear resistance of Q355B. Abrasive, impact, hardness and geometry change the result.

Contracted source framework
Open the complete comparisonFramework values apply only when contracted and confirmed for the order. Shipment conformity depends on the original mill EN 10204 3.1 document and GOREX release controls.

Open grade dossierGOREX 450
How should sliding abrasion, impact and workshop processing be balanced?
03500HBW

Open grade dossierGOREX 500
Does higher nominal hardness suit the real geometry, impact and process route?
03 / Field
Five operating fields. No universal grade.
A1
Buckets & attachments
Map sliding abrasion, impact zones and welded geometry.
A2Mining & quarry
Define material flow, fragment size and impact energy.
A3Recycling & demolition
Assess irregular impact, scrap edges and service intervals.
A4Material handling
Locate flow angles, transitions and wear paths.
A5Forestry & agriculture
Balance soil contact, stone impact and repairability.
04 / Core
Centre hardness enters qualification
Surface hardness is only the start. The GOREX qualification plan ties the finished wear part to verified source plate and requires both surface and centre checks, even where the base standard makes centre hardness optional.

Process from actual order data
Guidance supports decisions — it is not a universal parameter table.
Open technical centre01020304
Welding
Start from actual chemistry, combined thickness, heat input and a qualified WPS.
Cutting
Choose the method by thickness, heat-affected zone and cracking risk.
Bending
Check rolling direction, tooling, radius, surface and exclusion zone.
Machining
Secure machine rigidity, workholding, tooling and trial parameters.
07 / Release
Qualification before release
The first three released shipment lots target true EN 10204 3.2 only when the required independent or authorized validation is actually arranged. Every shipment is assessed against its specified inspection plan.
