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,

Subject: [MW:15305] Welding of IS 2062 Gr.D E450 (Fe570)
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 ? Regards Prem Nautiyal Cell: 9769316004 |
