SP 312 Metal spray wires




SP 312

 
CATEGORY 
TYPE 
Solid high Cr/Ni metal spray wire
APPLICATIONS 
Ceweld SP 312 is a Chromium- Nickel alloy for use at operating temperatures up to 1020°C. It contains a high chromium content for good corrosion resistance and remarkable strength properties, especially under conditions of frequent switching or wide temperature fluctuations. Used for heating elements in domestic appliances and industrial equipment. Ceweld SP 312 can be applied with the flame spray process and the electric arc process as well.
PROPERTIES 

Excellent corrossion resistance against many media and acid invironments. Good thermal shock resistance.
