Re: [MW:15312] Welding of IS 2062 Gr.D E450 (Fe570)

By Materials & Welding
Mr. Prem,

IS 2062 Gr.D E450 has a
YS   of 450 MPA min.
UTS  of 570 MPA min.
%EL  of 20
impact  45 joules at room temp.

Its chemistry as follows
c   0.22 max.
Mn  1.60  "
Si  0.45  "
S/P 0.045 "
Nb/V/Ti as trace elements to  0.15 max.
C.Equiv  0.46 max. and weldable.

Equal to Sailma 450H
Pre heat to  150-20deg.C if the thickness is above 20 mm.

Consumable selection:
ER80S-D2 for GMAW and E8018-G for SMAW is OK.

sridhar,

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 ?

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...
