Hardfacing with chromium addition has been a new technique and widely employed to extend the
service life of machine parts related to wear mechanisms. In this work, the effect of chromium from
high chromium martensitic stainless steel type 401 in hardfacing deposit was studied. Low carbon steel
electrode and martensitic steel electrode were used to deposit using submerged arc welding process. The
results revealed that the microstructure of low carbon steel deposit without chromium addition consists
of ferrite and pearlite. The microstructure of weld metal with chromium addition showed ferrite and
martensite. It can be seen that the increasing amount of additional chromium showed lower welding
dilution and higher hardness values of the weld layer. The microstructure and hardness values of welding
layer welded with chromium addition are different to those of welding layer welded with martensitic
steel type electrode without addition
