Re: [MW:15310] Welding of IS 2062 Gr.D E450 (Fe570)

By Materials & Welding
DEAR PREM,
Your steel IS 2062 Gr.D E450 (Fe570),more details available with SAIL salem plant,since they manufacture the same. Since its Min.UTS is 570N/mm2 which is equal to 82672 Psi, try your welding with ER80S-D2 for GMAW and E8018-G for SMAW use quality filler metals of Lincoln or Esab.make ,then go for Destructive test like UTS,Yield,Impact etc..(It has the carbon equivalent below 0.5 no need of any heat treatment.)
Regards
JIJILAL K.M.

Hi friends

 

We are using IS 2062 Gr.D E450 (Fe570) for a structural bridge fabrication work in India. The welding process to be used is SMAW and GMAW.

I would like to know the correct SMAW and GMAW consumable for welding IS 2062 Gr.D because very limited information is available about this steel.

ASME Sec IX 2011 addenda has included IS 2062 Gr A,B and C in P1 G1 category but still this steel is an unassigned one till date.

I would be using ER80S-D2 for GMAW and E8018-G for SMAW during PQR, is the selection correct ?

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...
