EFeMn-A 

Used for surfacing welding on parts of all kinds of     crushers, high-manganese steel rails, buckets, bulldozers, etc., which may     easily be worn out due to impact. 

EFeMn-B 

Used for surfacing welding on parts of all kinds of crushers,     high-manganese steel rails, buckets, bulldozers, etc., which may easily be     worn out due to impact. 

EFeCr-A1

Used for surfacing welding on occasions requiring intense     wear-resistance, corrosion-resistance and atmospheric corrosion-resistance,     such as axle bushes of centrifugal cracking pumps in petroleum industry,     parts of mining crushers, valve bonnets on diesel engines, etc. 

ECoCr-A

Used for the components under the impact and interlaced hot-cold     places. Such as high temperature and high pressure valve and the cutting     edge.

ECoCr-B

Used for high temperature and high pressure valve, shaft sleeve and     inner shaft sleeve of high-pressure pump, the cutting edge of fiber     equipment.

ECoCr-C

Used for welding wearing components such as bearing of rock bit,     rotating blade of boiler, pulverizer blade and spiral material feed.
