sathyasaravana0,
to the already given replies, coming from Prof. Crisi and Shane Feder I would like to allow myself to make a small addition.
The steel standardization you have mentioned appears to me to be based on the European Standards (EURONORM = EN).
The steel grades you have mentioned were - from my point of view - eligible to be welded with an electrode type E 7018. I will attach a German Electrode's suppliers (OERLIKON) data sheet for an E 7018 type, please see also SUPERCITO_pdf.
Furthermore I have searched the Internet to find a f.o.c. steel-standard comparison. I will attach a quite good one (source:
http://www.kvalitetstal.se), to see what the Euronorm Standard Steels mean in different other national standards, see also Standards_Comparison_pdf. Amongst others also the United States ASTM /AISI standard. I request your understanding its basically written in German language, but I guess it should be possible to perceive the most relevant information for you. The comparison should probably enable you to find the correct consumables for welding some of the most common European Steel grades in the future.
Best regards from Germany,
Stephan
