Preheat temperatures: The values rise with thickness, as minimum preheat temperatures do; read them as the minimum preheat for single-plate thickness (°C), and keep below the maximum interpass temperature in the next table.
- for thicknesses up to 13mm | Data from the table is applicable to single plate thickness when welding with a heat input of 1.7kJ/mm. | The consumables determine the preheating temperature if its carbon equivalent is higher than of the plate | Room temperature is approx 20°C

Choosing Nicrodur 450 Plates
Nicrodur 450 Plates is in the 450 HBW hardness class. Higher hardness generally lasts longer against sliding abrasion but is harder to bend, cut and weld; where parts also take heavy impact, a tougher, lower class can last longer.
| Class | Nominal hardness | Typical use | Forming and welding |
|---|---|---|---|
| 400 | About 400 HBW | Dumper bodies, chutes, hoppers, screens | Cold bending and welding with normal care |
| 450 (this page) | About 450 HBW | Buckets, liners and heavier wear parts | Larger bending radii; preheat thicker sections |
| 500 | About 500 HBW | Cutting edges, crusher and severe-abrasion liners | Limited forming; strict cutting and welding procedures |
Other Nicrodur classes
Brands of the same class are comparable, not identical; confirm any substitution with the end user. See all brands on Wear Resistant Plates.
Applications for Nicrodur 450 Plates
Typical uses include parts exposed to heavy wear from hard minerals and other abrasive materials. Tell us the abrasive material, impact level and the life of the current part so the right class can be quoted.
Cutting, Fabrication and Welding
Champak Industries describes full and part plate/profile supply and a plasma-cutting service. Thermal cutting softens a narrow edge zone, and thick or hard plate may need preheat before cutting. Weld with low-hydrogen consumables and the mill’s preheat and interpass limits; do not heat the plate above the mill’s tempering limit. See AR Plates for bending and drilling guidance.
Testing, Inspection Documents and Traceability
| Requirement | What to identify in the order |
|---|---|
| Mill test certificate | EN 10204 3.1 showing brand and grade, heat number, chemistry and hardness |
| Impact test | Charpy test temperature and minimum energy, if required |
| Traceability | Heat and plate number transferred to cut pieces |

02What hardness does Nicrodur 450 Plates have?
This page gives 420 – 477 HBW. Hardness ranges can fall with thickness, so confirm the guaranteed range for your thickness on the mill’s datasheet.
03Who makes this plate?
Nicrodur plate is made by Acroni. The mill and heat number are shown on the mill test certificate.
04Which thicknesses are listed?
This page lists 8 – 80 mm. Availability for each size is confirmed at quotation.
05Is Nicrodur 450 Plates the same as other 450 HBW wear plates?
Wear plates of the same hardness class are comparable, not identical. Chemistry, toughness and processing advice differ by mill, so confirm any substitution with the end user.
06Can Nicrodur 450 Plates be bent?
Yes, by cold bending with larger punch radii and die openings than mild steel. Follow the mill’s minimum radius for the thickness and rolling direction.
07Can Nicrodur 450 Plates be welded?
Yes, with low-hydrogen consumables and the preheat and interpass temperatures the mill gives for the grade and combined thickness.
08What is Nicrodur 450 Plates used for?
Typical uses on this page include parts exposed to heavy wear from hard minerals and other abrasive materials.
09Which certificate should I request?
An EN 10204 3.1 mill test certificate showing the brand and grade, heat number, chemistry and hardness, plus impact results where you specify a test temperature.
10How do I get a price and delivery date?
