Re: [MW:6954] AWS CODE FOR HARDFACING ELECTRODE

By Materials & Welding
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.

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

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

By Materials & Welding
Hi,  You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this.  Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime.  Again, these simulated no. Of cycles shall be specified in MTC.  The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case).  One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example.  In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
