Champak Industries' is a specialist supplier and exporter of thick BRINAR 450 Plates wear resistant steel plates. We understand customers whose requirement for wear resistant steel plate is extreme and who cannot use thinner abrasion resistant plates.
BRINAR 450 is wear-resistant, water-quenched and tempered steel produced by the Salzgitter Group. The high strength and good possibility of further working this steel is achieved by heating the material to 900°C and then cooling it in a water-quenching plant and if necessary subjecting it to tempering heat treatment.
Brinar 450 Plates: Purchasing Specification
| Requirement | What to specify |
|---|---|
| Brand and grade | Brinar 450 Plates; state whether another brand of the 450 HBW class is acceptable. |
| Hardness | 410 – 490 HB on this page; confirm the guaranteed range for your thickness. |
| Dimensions | Thickness × width × length and the number of plates, or a cutting drawing. This page lists Up to 80 mm. Sizes are confirmed at quotation. |
| Toughness | Charpy impact test temperature and minimum energy, where the part sees impact or cold service. |
| Processing | Cut-to-size parts, bending and edge preparation, with drawings and tolerances. |
| Documents | EN 10204 3.1 mill test certificate with chemistry and hardness. |
Application

- Stone mills
- Conveyors
- Materials handling systems
In cement works.
- Mixers,
- Screens,
- Hoppers
Also in the steel industry
- Scrap presses,
- Vibrating screens
- Crushers
BRINAR is produced in different grades
BRINAR 400/ BIRNAR 450/ BIRNAR 500 wear resistants' Plates.
BIRNAR 450 Plates produced up to 80mm thick. The surface hardness at room temperature is 410 – 490 Brinell. Cold working by bending or roll bending is possible provided the manufacturer's instructions are complied with. It can be cut thermally and welded with each standard procedure. In case of thermal cutting and welding the plate must be preheated from a thickness of 10mm.
Spelling: “BIRNAR” means BRINAR. Preheat thresholds for cutting and welding differ by grade and thickness; follow the mill’s datasheet.
Choosing Brinar 450 Plates
Brinar 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 Brinar classes
Brands of the same class are comparable, not identical; confirm any substitution with the end user. See all brands on Wear Resistant Plates.
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 |

Brinar 450 Plates: Frequently Asked Questions
01What is Brinar 450 Plates?
Brinar 450 Plates is wear-resistant steel plate in the 450 Brinell hardness class, made by the Salzgitter Group. It is used where abrasion shortens the life of ordinary structural steel.
02What hardness does Brinar 450 Plates have?
This page gives 410 – 490 HB. Hardness ranges can fall with thickness, so confirm the guaranteed range for your thickness on the mill’s datasheet.
03Who makes this plate?
Brinar plate is made by the Salzgitter Group. The mill and heat number are shown on the mill test certificate.
04Which thicknesses are listed?
This page lists Up to 80 mm. Availability for each size is confirmed at quotation.
05Is Brinar 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 Brinar 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 Brinar 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 Brinar 450 Plates used for?
Typical uses on this page include mining machines, cement works and steel-industry equipment such as crushers and screens.
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.
