DURMAT® A

Welding Rod DIN EN 14700: T Fe20(DIN 8555: G21-GF-55-CG)

General characteristics:

DURMAT A consists of a special pre-alloyed tube filled with coarsely grained FusedTungsten Carbide (FTC) for oxyacetylene welding. The FTC has an exceptionally highhardness of over 2360 HV0.1 giving outstanding wear protection to hard faced areas. Forspecial hard facing on machine parts of unalloyed, low alloyed or cast steel with carboncontent up to 0.45%. Higher carbon content could lead to cracking. Depending on the sizeand composition of the area to be hard faced, the proper rod diameter and grain size shouldbe chosen. If the area will encounter heavy abrasion a small grain size is recommended. Ifa cutting action is desired a larger grain size is preferable.

Application:

For hard facing and repairing tools and machine parts exposed to wear in mining, roadconstruction, ceramic, petroleum, excavation and dredging applications.

The area to be hard faced should be free of rust, scale, grease or other contamination.Slowly preheat the area to a maximum of 500°C (932°F). Sprinkle the surface withDURMAT Flux to prevent oxides from forming in the molten matrix during application. Oncethe area is properly heated, start brazing with DURMAT TINNING RODS (about 1mm layer).Now apply DURMAT CS. To facilitate the operation dip the end in brazing flux.NOTE: Do not overheat the hard faced area. Particles can be arranged in correct positionand dense configuration by using the end of the DURMAT–Tinning Rod. Slow cooling isadvised. Never cool area with water!

DURMAT® FTC

Fused Tungsten Carbide


Fused Tungsten Carbide (FTC) is one of the hardest and most abrasion resistant materialsused in the modern wear resistance and tool technology. FTC is the eutectic composition ofWC and W2C. The average carbon content of our FTC is 3.8 – 4.1 wt. % and the phasescan be estimated to be approximately 78 – 80% W2C and 20 – 22% WC.

Application:

Hard facing metallic surfaces exposed to extreme mechanical load. In this case FTC shouldbe used as a fine or coarser powder, which is embedded in the metallic matrix or isprecipitated into hard alloys. *Surface coating by thermal spraying or welding. Using powdermetallurgical processes, it is possible to produce parts of nearly any shape, which cancontain hard materials or diamonds together with a metal binder and FTC. *Reinforcing thehardness of diamond tools. FTC equalizes the matrices between the different harnesses ofdiamonds and binder in a diamond drilling, grinding and honing tools. Excellent for deepwell drilling tools and rods, crusher jaws, mixers, concrete and stone saws, hot-pressedtools, screens & conveyors, extrusion housings, hard additives to diamond bits and saws.

Hard Metal Specification


DURMAT WC-IV is produced from specially selected, uncoated, cleaned and straightWC/Co hard metal material grades. The WC/Co is carefully crushed and classified to avoidcontamination from iron, chromium and other elements normally present. Deposits arehighly resistant against abrasion. DURMAT–WC-IV is particularly well suited for cuttingtools. Hard facing with DURMAT–WC-IV has two advantages: concentrated wear protectionfor the area exposed to maximum wear and in addition easy application of an extremelyhard and abrasion resistant protective surface for highly stressed areas.

Application:

Mining, deep drilling–as on tool joints in the petroleum industry.

Classification:

DIN EN 14700T Fe16


DURMAT® FD 739 is an iron based flux cored wire containing complex carbide phaseswhich are precipitated more fine than in common used hardfacings. These layers show abetter resistance against abrasive and erosive load because of the finely divided hardparticles which have a submicron grain size. This fine structure results of the advantageconcerning the percentage contact area of the fine hard phases in comparison to commonhard phse grain sizes.

Application:

On parts with high abrasive and erosive load, which could be superposed by corrosiveattack.

Creative Ideas for Real Life Wear ProtectiveSolutionsDURUM GmbH has developed produced and distributed wear protective products for morethan 25 years. This knowledge and experience has enabled us to introduce new wearprotective coatingss to increase the lifetime of machinery and to reduce the costs formaintenance of wear and erosion of exposed surfaces and components.

In addition to delivering high quality wear protective materials to our customers, ourcompetent team consults in every specific application to provide tailor made solutions. Wehave the knowledge to provide engineering support for the design of new parts. Thesecomponents are tailor made and fabricated for machine parts, tubes, segments, mixerbarrels, bars and more. Used components can also be regenerated according to customerrequirements.

We offer:

• Wear plates (Open Arc and PTA)• Wear protective parts according to design requirements• Regeneration of worn parts• Coating of new parts, also full-production run• Consulting, development, conceptual design and wear analysis services

DURUM works with leading research institutes and universities in the development of newmaterials and technology for wear protection solutions. We analyze the customer’s wearproblems and provide the essential solution.

Combined research, development and integrated production is our guiding theme.

We work with the following universities:Technical University of Clausthal, University of Hannover, University of Ilmenau andTechnical University of Chemnitz.


Our welding workshop is certified according to the DIN EN 729.3:


CP - wear plate

The fabrication of the CP – plate is carried out by use of a core wire welding process. Theextreme wear resistance is achieved by use of high quality CORODUR core wireconsumables with high Chromium and Carbon content. The addition of complex carbidesenables the formation of a high content of Chromium- and special carbides, so that therequired 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. The content ofthe primary carbides mainly affect the wear resistance and can be determined according toMaratray as follows:

% K = 12.33 (% C) + 0.55 (% Cr) – 15.2 %

The increasing carbide content is related to steady rises of the Cr- and C content.

Through application of core wires CORODUR 56 and 62, the primary carbide content can beincreased significantly. The addition of complex carbides e.g. NbC subsequently increasesthe wear resistance performance of the plates.
