Flux-cored wire for COBALT-BASED ALLOYS
MF20-GF-55-CGTZ 52-55 HRC | C:2.4 Si: 0.7 | F-S 1 deposits a cobalt-based alloy with an austenitic-ledeburitic structure. This is the hardest of the standard cobalt-based alloys. It has a high resistance to corrosion, especially lo reducing acids, impact, extreme wear and temperature shock. The alloy is machinable only by grinding. Best used on wear pads. rotary seal rings. pump sleeves and centreless grinder work rests |
| MF20-Gr-45-CTZ 40-43 HRC 36-39 HRC 43-46 HRC | C: 1.1 (0.8) (1.3) Si: 1 Mn: 0.6 Cr: 28 W: 4.5 Co: res. Fe:<2,6 | Cobalt-based alloys with an austenitic-ledeburitic structure hearing chromium and tungsten carbides. These alloys are highly resistant to corrosion and abrasion, high impact stress and extreme temperature shock. The deposit is machinable with hard metal tools. Best used on steam and Chemical valves and on equipment handling hot steel, such as tong bits. shear blades, etc. |
| MF20 GF 50 CTZ 45-48 HRC | C:1-4 Si: O.8 Mn: 0.1 Cr: 29 Co: res. W: 8 Fe: < 2.5 | Cobalt-based alloy with high resistance to abrasion, temperature shock and corrosion. This alloy is suitable for hardfacing cutting edges of long knives and other tools used in the wood, plastic, paper, carpet and Chemical industries |
| MF20-GF -350-CKTZ 275-325 HB work-hardened approx. 45 HRC | C: 0.25 Si: 0,8 Mn: 0.3 Cr: 27 Ni: 2.5 Mo: 5.5 Co: res. Fe:< 2.5 | This cobalt-based alloy is the toughest, with highest corrosion and thermal resistance of all cobalt-based alloys. The weld deposit is machinable and is used on components that are exposed to high temperatures, corrosion and impact stress, such as valve seats as well as components in the chemical industry. |
