    Welding 4140 is a lot like welding 4130 which is a lot like welding plain old steel. Except for being more crack sensitive and therefore needing a preheat before welding on certain applications, the puddle looks very much the same as welding plain carbon steelbest machining 4140 alloy steel thats because the composition is so similar. 4130 and 4140 are low alloy steels.

  18. machining 4140, Engineers Edge Forum, www.engineersedge.com

    Although there are several materials tougher and of which work harden more readily, it is a strong consideration while machining 4140 steel. One reason is because poor drilling methods (or with dull drills) may weld or embed protions of the drill itself into the work area. This creates a serious problem often resulting in the work being scraped.Some results are removed in response to a notice of local law requirement. For more information, please see here.
