I just want to make sure the switch to the higher grade material will be worth the change.

ASTM A AM for High Strength Steel Castings for Structural Industry

Yes, typically as the carbon content is lowered because of lower strength requirements the weldability of the steel increases, where preheat and other measures to prevent cracking are less likely.

I noticed the Manganese is less for A27, does that mean it welds better or easier? The carbon equivalent CE equation is used to evaluate “weldability” of steel x148 or wroughtwhere besides carbon content, other alloying elements as arunmrao mentioned are considered. Defense manufacturing is all about project manufacturing and project accounting.

Because of their lower strength, fewer precautions are required for welding, in comparison to higher strength grades, and they are less sensitive to cracking during or after welding.

MechEng; Given your statement above, Quote: The issue of gradee susceptibility does not factor in given the statement above. However,certain precautions need to be taken before welding. Can you quantify it, maybe with carbon content of either? I got the values, as I make those grades of castings.
