Powder Name	Description	Applications	Approx Hardness	Nominal Composition
MSSA 101	Produces coatings to resist wear by fretting at low temperature	Flap Tracks Cam Followers Conveyor Screws Pump Sleeves Steel Mill Rolls Hydraulic Rams	50-55 Rc	Co 12%, Wc Bal
MSSA 103	MSSA 103 is a metal bound carbide powder for wear resistant coatings produced by flame, plasma or high- velocity-flame-spraying (HVOF).	Similar applications to 101 with a slightly lower hardness	1000 HV	Ni 12%, WC Bal
MSSA 105	Preferably HVOF sprayed, very dense coatings can be achieved with extreme hardness of HV 0.2 1000-1300 and tensile strength of more than 70 N/mm2.	Gate Valves Pump Components Bearing Journals Mandrels Valve Components Oil & Gas	1000 – 1300 HV	Cobalt 10%, Tungsten Bal, Chromium 4%
MSSA 106	In comparison with WC/Co coatings MSSA 105 and 106 shows a higher resistance against oxidation and corrosion in aqueous solutions and can be operated up to maximum of 650°C.	Gate Valves Pump Components Bearing Journals Mandrels Valve Components Oil & Gas	1000 – 1300 HV	Cobalt 6%, Tungsten Bal, Chromium 8%, Iron <2%, Nickel <0.5%, Carbon 3.5%
MSSA 108	In comparison with WC/Co coatings MSSA 108 shows superior oxidation and corrosion resistance properties. In addition it has a better chemical resistance than other WC-based materials.	Wet Corrosive Environments Oxidizing Atmospheres Gate and Ball Valves Furnace Rolls	1400 HV	Tungsten Carbide Bal, Chromium Carbide 20%, Nickel 7%
MSSA 251	MSSA 251 powder produces dense, well bonded and very hard coatings which is suited for hard surfaces, fretting or abrasive wear. The coating is also resistant to corrosion, heat and oxidation temperature up to 800°C.	Turbine Components Baffle Dampers Fuel Rod Mandrels Hot Crushing Rolls Other Fretting Wear applications in environments up to 1400°F.	53-57 Rc	CrC 75%, Nickel 20%, Chromium 5%
MSSA 825	MSSA 825 powder is made exclusively for metal spraying. MSSA 825 is a Chromium Carbide-Nickel-Chromium powder produced by agglomerating and sintering.	Pump Housings Machine Parts Hydraulic Valves Tooling Hot Forming Dies Boiler Applications – used by Babcock Hitachi in Japan		Carbide Balance, Chrome  20%
MSSA 885	MSSA 885 coatings are used for high temperature applications above 500oC where standard WC coatings will oxidize. Coatings produced offer excellent high temperature stability, oxidation and corrosion resistance	Sliding wear Hot Gas Erosion Cavitation	900 – 1100 HV	Ni 18 – 22%, C 9 – 11%, Cr  Balance
MSSA 1274	MSSA 1274 results in smooth coatings which are of medium hardness RC 50-53, dense and corrosion resistant. Good finishes can be achieved with little stock removal.	Particle erosion wear at temperatures to 1500oF (815oC) Pump Cavitation Wear Fretting Wear Power Generation “Soot Blower” erosion Low Temperature Sliding Wear Pump Sleeves Glass Mold Dies Hot Forming Dies Forging Tools Replacement for Hard Chrome plating	Approx 40 Rockwell C	Nickel, Chromium, Silicon, Boron
MSSA 1275	MSSA 1275 powder is made exclusively for thermal spraying. Spraying with MSSA 1275 results in smooth coatings which are hard 60-62 Rc, dense and corrosion resistant. Good finishes can be achieved with little stock removal.
