| DURMAT® | Chem. composition | Hardness | Applications | Features | Classification |
|---|---|---|---|---|---|
| E | Fe base with WSC | Mixed hardness of weld metal: 55-58 HRC | Armoring of tools and machine parts in mining, road construction, special civil engineering, well construction, deep drilling technology | Immersed tubular electrode for electrical hardfacing on non-alloy and low-alloy steels | E Fe20 | E21-GF-UM-60-CG |
| E-PLUS | Fe base with SWSC | Mixed hardness of weld metal: >58 HRC | Armoring of tools and machine parts in mining, road construction, special civil engineering, well construction, deep drilling technology | Similar to DURMAT® NIFD, but filled with spherical tungsten fused carbide (SWSC) | E Fe20 | E21-GF-UM-60-CG |
| NI3 | Ni-base with WSC and special carbides (SC) | WSC: 2.360 HV0.1 Matrix: 480-520 HV0.1 Special carbides (SC): 2,900 HV0.1 | Mixer blades, processing plants for molding sand, slurry pump valves, screw conveyors, deep drilling tools, corrosion-resistant coatings against heavy abrasive wear in the chemical and food industries | Similar to DURMAT® NIFD, but filled with spherical tungsten fused carbide (SWSC) | T Ni20 | MF21-55-CGZ |
| NI3-PLUS | Ni-base with SWSC and special carbides (SC) | SWSC: 3.000 HV0.1 Matrix: 480-520 HV0.1 Special carbides (SC): 2,900 HV0.1 | coatings on steels, casting tools, nickel alloys and stainless steels (mixer blades, preparation equipment for molding sand, slurry pump valves, screw conveyors, grinding plates, stabilizers, deep drilling tools) | Stick electrode made of an extra hard W-Ni alloy Excellent abrasion wear behavior, heat and corrosion resistance | E Ni20 | E21-GF-UM-60-CGZ |
| NISE | Ni base with WSC | WSC: 2.360 HV0.1 Ni-Matrix: ≈ 480-520 HV0.1 | coatings on steels, casting tools, nickel alloys and stainless steels (mixer blades, preparation equipment for molding sand, slurry pump valves, screw conveyors, grinding plates, stabilizers, deep drilling tools) | Stick electrode made of an extra hard W-Ni alloy Excellent abrasion wear behavior, heat and corrosion resistance | E Ni20 | E21-GF-UM-60-CGZ |
| NISE-PLUS | Ni-base with SWSC | SWSC: 3.000 HV0.1 | coatings on steels, casting tools, nickel alloys and stainless steels (mixer blades, preparation equipment for molding sand, slurry pump valves, screw conveyors, grinding plates, stabilizers, deep drilling tools) | Similar to DURMAT® NIFD, but filled with spherical tungsten fused carbide (SWSC) | E Ni20 | E21-UM-60-CGZ |
