| Documents | EN 10204 3.1 mill test certificate with chemistry and hardness. |
Typical Mechanical Properties
- Brinnell Hardness – 400/440 BHN
- Tensile Strength – 180,000 PSI
- Yield Strength – 140,000 PSI
- Grain Type – Temp. Martensite
- Carbon Equivalency – .47
- Elongation– 15%
- Reduction of Area – 60%
Typical values: “Brinnell” is Brinell. These are typical values for one mill’s AR 400, not guaranteed minimums: 180,000 psi is about 1240 MPa and 140,000 psi about 965 MPa, and “.47” is a carbon equivalent of 0.47. The paragraph above gives the hardness range as 360–440 BHN. Ask for the mill’s datasheet for guaranteed values.

Choosing AR 400 Plates
AR 400 Plates is in the 400 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 (this page) | About 400 HBW | Dumper bodies, chutes, hoppers, screens | Cold bending and welding with normal care |
| 450 | 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 AR 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 AR 400 Plates
Typical uses include mining equipment, truck-trailer bodies, chutes and material handling. 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 |

AR 400 Plates: Frequently Asked Questions
01What is AR 400 Plates?
AR 400 Plates is wear-resistant steel plate in the 400 Brinell hardness class, ordered by hardness class, with the mill named on the certificate. It is used where abrasion shortens the life of ordinary structural steel.
02What hardness does AR 400 Plates have?
This page gives 360 – 440 BHN. Hardness ranges can fall with thickness, so confirm the guaranteed range for your thickness on the mill’s datasheet.
03Who makes this plate?
AR 400 is a hardness-class name used by several mills. The mill supplying your order is named on the mill test certificate.
04Which thicknesses are listed?
This page lists 1/8″ – 4″. Availability for each size is confirmed at quotation.
05Is AR 400 Plates the same as other 400 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 AR 400 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 AR 400 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 AR 400 Plates used for?
Typical uses on this page include mining equipment, truck-trailer bodies, chutes and material handling.
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.
