STEEL SELECTION FOR FIELD REPAIR

[robsb123]

I need some assistance in choosing a grade of steel We are welding a solid steel forging (4"x6" cross section) to a 1" thick A36 plate. Can anyone recommend a grade of steel that would offer maximum strength/hardness without the need of post weld heat treatment. We will be taking this piece of equipment out of service to make the repair, so downtime is going to be a major issue. I am thinking a low to medium carbon steel. Does anyone have any good suggestions (relatively cheap is best, since we will be eating this cost)
Thanks,

Your post is to general to provide any guidance. What is the problem with the existing forging that you need to replace it? What exactly is the type of repair and equipment?
