P-Ni 46 PTA

General Information

PT-MAT™ Ni 46 PTA is a Ni,B,Si based metal powder used for Hard facing or as a buffer layer for coating with a higher hardness. The alloy shows good corrosion resistance despite low Cr content, the alloy also contains low level of Fe and Carbon.


PT-MAT™ Ni 46 PTA is applied through plasma powder surfacing or laser cladding on low alloy to high alloy steel.
The powder exhibits excellent weld ability and a very fluid puddle.
The low level of Fe and C makes it a good candidate to overlay stainless steel components even in single pass.
The medium range hardness makes the coating suitable for machining.
