Dear experts,         How do you call this below given material and how to select electrodes should we take operating temperature into account or only like tensile strength of the material and its chemaical composition? Is this carbon steel or low alloy steel since the chemical compositions is 1 1/4Cr-1/2Mo it is lessthan 7% of its total composition or should we call it as cromolly? I had selected this electrode E8016B2 is this ok? I have given preheating 125 deg centigrade and PWHT too. How do we find out the soaking time and rate of raising temp?   A335 Gr P11    Can anybody reply me please and I will be so pleased.   Regards Ilangkumaran
