Dear sir,
Let me know the AWS code for hardfacing electrodes used for achieving Hardness upto 55-60 HRC.

Dear Pramod,

Normally for hardfacing electrodes, there is no AWS codes and all. As you know well, depending upon the applications, wear factors and base metal history, we will select and recommend the suitable hardfacing electrode. Moreover, achieving the hardness of 55 to 60 HRC by hardfacing electrode can be done even with single chemical element. It doesn't matter. But, the weld metal chemistry (chemical composition), weld matrix, dilution and welding process are very very important to provide the expected wear resistance, prolong the service life, reduce the downtime of the base metal. We have to always analyse the applications and wear factors in all the aspects. 

1. Abrasion. 2. Erosion 3. Corrosion 4. Heat Oxidation 5. Cavitation. 5. Impact. 6.Friction.

According to application, wear factors, base metal chemistry, & required wear resistance,
the weld metal chemistry should be. So, only for hardness, we could not say the chemistry. 

But, instead of AWS codes, for mostly all hardfacing electrodes, we have DIN standard. 

If you are in india or any other country, you can contact Bohler Welding Group 
engineers who will really help and support you in technical things. Bohler is a world renowned company and the master of welding solutions and services.

Thanks and Regards,

You can refer AWS A 5.13 spec. E Fe3 electrode.  Eventhough hardfacing spec. exists, many of the manufacturers are not mentioning their specs in their catelogues. 
 
There are two type of hard facing electrodes one is Air hardening electrodes and another is work hardneing electrodes.   You can refer this spec. for details.

You can use DIN8555 for hardfacing guid
