HALDEN Wear Plate Grade
H-400 High Temperature Plate
High-temperature wear plate for abrasive service where heat, thermal cycling and hot particles shorten the life of standard liners. H-400 is recommended for boilers, cyclones, sintering equipment, clinker handling and hot ash transfer areas.
| Grade | H-400 High Temperature Plate |
| Wear condition | High-temperature abrasive wear 高温磨损工况 |
| Typical hardness | HRC 58-65 |
| Common thickness | 8+6, 10+8, 10+10, 12+12 and customized |
| Main applications | Boilers, cyclones, sintering, hot material conveying |
Wear protection for hot abrasive material areas
HALDEN H-400 High Temperature Plate is designed for wear positions exposed to elevated temperature and abrasive flow. It helps customers protect equipment where ordinary wear plate may lose performance, deform, crack prematurely or suffer from shorter service life under heat.
This grade should be selected according to real working temperature, thermal cycling, impact level and handled material. HALDEN can help review drawings and working conditions before recommending the overlay structure and base plate.
Key benefits
- Designed for abrasive wear under elevated temperature
- Suitable for hot ash, clinker, sinter and heated bulk materials
- Can be fabricated into liners, shields, chute plates and pipe sections
- Recommended when standard liners fail quickly in hot wear zones
Typical specifications
| Overlay type | Chromium carbide or custom alloy hardfacing layer |
| Base plate | Q235, Q345, A36 or equivalent weldable steel; special base plate available by project |
| Hardness | HRC 58-65 |
| Plate format | Standard sheet, cut-to-size liner or fabricated wear component |
| Processing | Cutting, bending, rolling, drilling, countersunk holes, stud welding and welding assembly |
Recommended applications
| Boiler wear areas For selected shields, liners and ash handling wear positions. | Cyclone separators For abrasive inner liners and hot particle flow areas. |
| Sintering equipment For steel plant sinter and hot material handling zones. | Hot clinker transfer For cement plant clinker discharge and transfer equipment. |
| Hot ash conveying For power plant ash transfer and collection systems. | Thermal wear liners For liner kits requiring both heat resistance and abrasion control. |
When to choose H-400
| Condition | H-400 suitability | Recommendation |
|---|---|---|
| Room-temperature ordinary abrasion | More than needed | H-100 may be more cost-effective. |
| Severe room-temperature abrasion | Possible, but not necessary | Consider H-200 Severe Abrasion Plate. |
| Powder or sticky material flow | Depends on temperature | Consider H-300 if smooth flow is more important. |
| High-temperature abrasive wear | Good fit | Use H-400 after confirming working temperature. |
| Heavy impact plus heat | Needs review | HALDEN should review impact level and temperature together. |
