| Hardcarb 5001 | Hardfacing / superalloys | cobalt base | Bare TIG rod | DIN EN 14700: R Co3 | Pump sleeves, rotary seal rings, wear pads, expeller screws and bearing sleeves | The deposit is a cobalt base alloy of austenitic ledeburitic structure with embedded CrW carbides. It is the hardest of the standard Cobalt base alloys. The weld metal is highly resistant to corrosion, impact, abrasive wear as well as thermal shocks and heavy mechanical impact. The deposits are only machinable by grinding. | 55 HRC | ||||||
| Hardcarb 5006 | Hardfacing / superalloys | cobalt base | Bare TIG rod | DIN EN 14700: R Co2 | Steam valves, hot shear blades, hot pressing dies, pumps for high-temperature liquids, etc | The weld metal is highly resistant to corrosion, impact, abrasive wear as well as thermal shocks and heavy mechanical impact. Most widely used of the wear resistant cobalt-based alloys and exhibits good all-round performance. Weld metal can be machined with carbide tools. | 42 HRC | ||||||
| Hardcarb 5012 | Hardfacing / superalloys | cobalt base | Bare TIG rod | DIN EN 14700: R Co2 | Hardfacing of cutting edges of long knifes and other tools used in the wood, plastic, paper, carpet and chemical industry. It is also used for hardfacing of engine valves, pinch rollers and rotor blade edges. | Good resistance to metal and mineral abrasion combined with corrosion and high temperature up to 700°C, in the presence of moderate shocks. Highly resistant to erosion and cavitation. Highly recommended for deposits stressed by temperature, corrosion, abrasion and impact. Weld metal can be machined with carbide tools. | 46 HRC | ||||||
| Hardcarb 5021 | Hardfacing / superalloys | cobalt base | Bare TIG rod | DIN EN 14700: R Co1 | Industrial valve work, forging dies and hot shearing blades. | Alloy is resistant to abrasion, cavitation, galling, and corrosion and retains these properties at high temperatures. Excellent metal-to-metal sliding wear resistance, but is not recommended for severe hard particle abrasion. The weld metal is highly resistant to impact and is work- hardening up to 45 HRC. | 300 - 330 HB (as welded), 45 HRC (work hardened) |
