| 41.0 – 50.0 | 0.65 | 0.50 |
Reading the chemistry: Element limits are given only for 21–40 mm plate; the other rows give carbon-equivalent limits (CE and Pcm) only, so ask for the full analysis for your thickness.
Tolerances
| Thickness | Thickness tolerance as per EN 10029. Narrower tolerances can also be offered. |
| Length and Width | Tolerances as per the requirements of EN 10029 |
| Flatness | Tolerances as per the requirements of EN 10029 Class N |
| Surface Properties | Tolerances as per the requirements of EN 10163-2, Class A Subclass 1 |
Welding & Cutting
| Welding Method | All conventional welding methods like manual electric welding, submerged arc welding, inert gas welding |
| Preheating (Welding & Cutting) | Maximum 200°C for thickness greater than 20 mm |
Preheating: This line means plate over 20 mm thick needs preheating for welding and cutting, with the preheat temperature not exceeding 200 °C. Follow the mill’s preheat table for the exact temperature.
Choosing ARCELOR 450 (Nippon Steel Make In India)
ARCELOR 450 (Nippon Steel Make In India) 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 ARCELOR 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 ARCELOR 450 (Nippon Steel Make In India)
Typical uses include crushers, truck-bed liners, buckets, hoppers, chutes and conveyor troughs. 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 |
