Description
The VANFORGE wear plate that can take the heat
TEMP is a high-heat grade of wear plate that provides a cost-efficient solution for wear resistance at high temperatures in the 300–500°C range (570–930°F).
Whereas traditional quenched and tempered wear-resistant steels lose hardness at higher temperatures, TEMP high-temperature steel delivers extreme wear resistance. Its properties are achieved by using high-quality raw material combined with a carefully controlled manufacturing process.
TEMP is delivered as 4.7 – 51.0 mm (0.197’’–2’’) plate. It can be cut, welded and machined using the same kind of machinery and technology as for conventional steel.
Dimension Range
TEMP is available in thicknesses of 4.7 – 51.0 mm. TEMP is available in widths up to 3350 mm and lengths up to 14630 mm. More detailed information on dimensions is provided in the dimension program.
Mechanical Properties
| Thickness (mm) | Hardness (1) (HBW) | Typical yield strength (MPa), not guaranteed |
| 4.7- 51.0 | 375- 425 | 1100 |
(1) Brinell hardness, HBW, according to EN ISO 6506-1, on a milled surface 0.5 – 3 mm below surface. At least one test specimen per heat and 40 tons.
The nominal material thickness will not deviate more than ± 15 mm from that of the test specimen.
It is through-hardened. Minimum core hardness is 90% of the guaranteed minimum surface hardness.
Impact Properties
| Grade | Longitudinal test, typical impact energy, Charpy V 10x10 mm test specimen. (1) |
| TEMP | 60 J/-40 ºC |
(1) Impact toughness measured upon agreement. Impact testing according to ISO EN 148 per heat and thickness group. Average of three test.

Fabrication and Other Recommendations
Welding, bending and machining.
TEMP is not intended for further heat treatment. It has obtained its mechanical properties by quenching and when necessary by means of subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 500 ºC.
Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on this product. Grinding, especially of primer coated plates, may produce dust with a high particle concentration.
