DURUM wear plates
The fabrication of the CP - plate is carried out by use of a core wire welding process. The extreme wear resistance is achieved by use of high quality DURUM core wire consumables with high Chromium and Carbon content. The addition of complex carbides enables the formation of a high content of Chromium- and special carbides, so that the required properties are achievable in the first layer in accordance to the DIN 855 E10-60G. The characteristic, hypereutectic weld metal of the FeCrC-hardfacing alloy consists of large, primary deposited carbides of the type M7C3, embedded in the eutectic matrix.
DURMAT- CP - plates can be delivered as pre-finished blanks with fixation elements, sinkhole bores or others. Recoating is carried out with similar alloy electrodes or core wires.
DURUM - PLATINUM - WEAR PLATES
The PLATINUM plate, fabricated with the high performance welding process PTA (Plasma Transferred Arc), is the answer to the increasing demands to improve profitability and productivity in the heavy industry where we are able to apply special Iron based alloys. Primary carbides in combination with Ni-, Co and Fe based alloys improve the wear resistance significantly, compared with conventionally welded Cr-carbides. High wear resistant Fused Tungsten Carbides (FTC) in combination with a Ni-alloy offer excellent protection against sliding, grooving and rolling wear. The Ni-based alloy offers exceptional properties for temperatures up to 500°C. The PTA process features a metallurgical bond with a dilution limited to 5 - 10%. A further advantage is the fabrication of thin wear plates which can be used to manufacture weight optimized protective components (e.g. fan blades)

| Product | Matrix | Description and application |
| DURMAT CP 960 | FeCrC | DURMAT-CP 960 is a composite hardfacing plate consisting of a weldable steel plate and a wear resistant coating composed of the core wire DURMAT FD 55. The hardfaced coating of C-Cr-alloy is related to the alloy group Fe14 according to EN 14700 (group 10 former DIN 8555). Chromium carbides in combination with borides and other metals produce an adamantine and wear resistant coating. These coatings are useful in the ceramics industry, mineral crushing, mining industry, fan and other applications that have high demands for wear resistance. |
| DURMAT CP 1000 | FeCrNbC | DURMAT-CP 1000 is a composite hardfacing plate consisting of a weldable steel plate and a wear resistant coating composed of a core wire coating DURMAT FD 60. The hardface coating of C-Cr-alloy with additional incorporated complex carbides related to the alloy group Fe15 according to EN 14700 (group 10 former DIN 8555). Chromium- and Niobium-carbides in combination with borides produce an adamantine and wear resistant coating applied for components exposed to energizing wear. This is not suitable for impact and impinging loads. This is useful for cement and concrete pumps, coatings for the ceramics industry, mineral rushing, mining industry, fan and recycling industries. |
| DURMAT CP 1100 | FeCrC + complex carbides | DURMAT-CP 1000 is a composite hardfacing plate consisting of a weldable steel plate and a wear resistant coating, which offers high wear protection against abrasion and moderate impact and impinging load. The coatings are temperature resistant up to 650°C as well as qualified for corrosion protection. The coating of a C-Cr-alloy with additional incorporated complex carbides of the type CrC, VC, MoC, WC and MoC is related to the alloy group Fe16 according to EN 14700 (group 10 former DIN 8555). Steel fabrication, fans in the hot gas area, foundries |

| DURMAT 1061 WP | PTA
+ Ni-B-Si + FTC |
DURMAT®-1061 WP is a composite hardfacing plate consisting of a weldable steel plate and a wear resistant coating. The hardfacing layer consists of a Ni-B-Si matrix alloy with embedded Fused Tungsten Carbide (FTC). The Chromium free alloy enables higher hardness compared to the M7C3 type and comprises higher matrix hardness. The incorporated FTC offers a specific hardness larger than 2.340 HV0.1. The low melting point of the matrix alloy, as well as the plasma processing of the composite material, enables a metallurgical bonding to the base material and a minimized dilution. To be applied to sliding, grooving, rolling impact wear; superior properties for temperatures up to 500°C. |
| DURMAT 1062 WP | PTA
+ Ni-B-Si + SFTC |
DURMAT®-1062 WP is a composite hardfacing plate consisting of a weldable steel plate and a wear resistant coating similar to the 1061 WP. Contrary to the 1061 WP Spherical Fused Tungsten (DURMAT-SFTC), carbide particles are embedded into a Ni-B-Si matrix to achieve a high performance wear resistance coating. SFTC is known as one of the hardest and most wear resistant materials and achieves hardness values over 3000 HV0.1. The low melting point of the matrix alloy, as well as the plasma processing of the composite material enables a metallurgical bonding to the base material and a minimized dilution. To be applied to sliding, grooving, rolling impact wear; superior properties for temperatures up to 500°C. |
| DURMAT 1401 WP | PTA + Ni-Mo-Cr + FTC |
DURMAT®-1401 WP is a composite hardfacing plate consisting of a weldable ferritic or austenitic steel plate and a combined wear and corrosion resistant coating. The hardface coating consists of corrosion resistant NiCrMo-alloy reinforced with FTC. The Mo- and Cr matrix alloy allows the application even under corrosion loads up to working temperatures of 600°C. The reinforcing FTC reveals hardness larger than 2,340 HV0.1. By the use of the unique PTA system, a metallurgical bonding to the base material and a minimized dilution is achieved. To be applied to sliding, grooving, rolling impact wear; superior properties for temperatures up to 600°C, good corrosion resistance |
