Champak Industries' is a specialist supplier and exporter of thick 500 HB wear resistant steel plates. We have HB 500 abrasion resistant plates in stock with a focus on heavier plates between 50mm to 150mm.
We understand customers whose requirement for wear resistant steel plate is extreme and who cannot use thinner abrasion resistant plates. Typical usages for our heavy 500HB plates are for penstock construction in the hydroelectric and mining industries.
Thick plates are also used for very large earth moving and excavating machines whose capacity to move huge tonnages requires a corresponding increase in the structural strength of the steel and its thickness.
Finally customers use the thinner wear resistant plates for the entire range of slide conveyors, chutes, silos, deflectors, screen plates, cutting edges, dump trucks and loading shovels that are required by the mining and construction industries.

Dillidur text: This page describes Dillidur plate from Dillinger. The comparison of European with Chinese and Indian mills is the original text’s opinion, so compare the datasheets of the brands you are offered. “SELECTIO” means selection, and “Widths 200 mm” should most likely read 2000 mm. In the table, “355 L” appears as DILLIDUR 325 L on the Dillidur pages.
Choosing HB 500 Plates
HB 500 Plates is in the 500 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 | About 450 HBW | Buckets, liners and heavier wear parts | Larger bending radii; preheat thicker sections |
| 500 (this page) | About 500 HBW | Cutting edges, crusher and severe-abrasion liners | Limited forming; strict cutting and welding procedures |
Other HB 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 HB 500 Plates
Typical uses include penstocks, large earthmoving machines, conveyors, chutes, screens and dump trucks. 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 |

What Determines the Quotation?
Brand, hardness class, thickness, plate size, quantity, cutting, testing and packing all affect the quotation. Say whether pricing is needed per kilogram, per plate or per finished piece.
Packing, Dispatch and Export Requirements
Give the delivery address, required date and unloading constraints. For export orders, include the destination port, delivery terms and document list.
HB 500 Plates: Frequently Asked Questions
01What is HB 500 Plates?
HB 500 Plates is wear-resistant steel plate in the 500 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 HB 500 Plates have?
This page gives 500 HB nominal. Hardness ranges can fall with thickness, so confirm the guaranteed range for your thickness on the mill’s datasheet.
03Who makes this plate?
HB 500 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 Up to 150 mm. Availability for each size is confirmed at quotation.
05Is HB 500 Plates the same as other 500 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 HB 500 Plates be bent?
Only with large bending radii and die openings, as 500-class plate has limited formability. Follow the mill’s minimum radius for the thickness.
07Can HB 500 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 HB 500 Plates used for?
Typical uses on this page include penstocks, large earthmoving machines, conveyors, chutes, screens and dump trucks.
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.
