Champak Industries' is a specialist supplier and exporter of FORA 400, FORA 450 and FORA 500 wear resistant steel plates. Wear Resistant Steel - Fora 400 is mainly used in abrasive conditions. It is water satiating martensitic steel with a distinctive hardness of 400 HB. Due to its elevated rigidity, robustness and high yielding strength, this steel is used where descending wear resistance is required. When compared to conventional steels, Fora 400 provides genuine benefits to equipment and allows a considerable thickness reduction. In addition to this, Fora 400 is up to 3 times more wear resistant than S355 grade steel. Offered steel is effortlessly welded and proves best for farming properties.
Reading the description: “Water satiating” means water-quenched, and “descending wear resistance” means high wear resistance. The comparison with S355 is mill guidance; actual wear life depends on the abrasive and the duty.
Fora 400 Plates: Purchasing Specification
| Requirement | What to specify |
|---|---|
| Brand and grade | Fora 400 Plates; state whether another brand of the 400 HBW class is acceptable. |
| Hardness | 400 HB typical on this page; confirm the guaranteed range for your thickness. |
| Dimensions | Thickness × width × length and the number of plates, or a cutting drawing. 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. |

Features
- Dimensional accuracy
- Sturdy structure
- Durability
- High tensile strength
- Wear & corrosion resistant
- Maintenance free
About these features: Wear plate resists abrasion, not corrosion: it rusts like other carbon and low-alloy steels, and wear parts still need inspection and replacement.
Applications
This steel is particularly suitable for applications in:
- Quarries, construction and earthmoving equipment
- Cement plants
- Mining industry
- Iron and steel industries
Mechanical Properties
| Hardness | Yield Strength | UTS | E 5.65 vS ? (%) | KCV Transv. - 20(F) | KCV Transv. - 40(F) |
|---|---|---|---|---|---|
| 400HB | 1100 N/mm | 1350 N/mm | 13 | 35J/cm(t=15mm) 65J/cm(t= 5mm) |
20J/cm(t=15mm) 45J/cm(t= 5mm) |
| 42.5 HRC | 160 Ksi | 195 Ksi | 13 | 21ft.lbs(t=15mm) 38ft.lbs(t= 5mm) |
12ft.lbs(t=15mm) 27ft.lbs(t= 5mm) |
Reading the table: “E 5.65√S” is elongation on a 5.65√S0 gauge length, and strengths are in N/mm². KCV values are Charpy V-notch energies in J/cm² at −20 °C and −40 °C for 15 mm and 5 mm plate. These are typical values; ask for the guaranteed values for your thickness.

Choosing Fora 400 Plates
Fora 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 Fora 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 |

Fora 400 Plates: Frequently Asked Questions
01What is Fora 400 Plates?
Fora 400 Plates is wear-resistant steel plate in the 400 Brinell hardness class, made by Industeel. It is used where abrasion shortens the life of ordinary structural steel.
02What hardness does Fora 400 Plates have?
This page gives 400 HB typical. Hardness ranges can fall with thickness, so confirm the guaranteed range for your thickness on the mill’s datasheet.
03Who makes this plate?
Fora plate is made by Industeel. The mill and heat number are shown on the mill test certificate.
04Which thicknesses are listed?
This page does not list a thickness range; send the thickness you need and availability will be confirmed at quotation.
05Is Fora 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 Fora 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 Fora 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 Fora 400 Plates used for?
Typical uses on this page include quarry, construction, earthmoving, cement and mining equipment.
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.
