Regarding the issue of burrs

GB150 specifies that containers with undercutting are not allowed, including those made of CrMo low-alloy steel. I wonder why the standard mentions low-alloy steel

When welding low-alloy structural steel, the edge of the undercut becomes hardened, and due to stress concentration, it often becomes a cause of welding cracks.
