This post was last edited by Cuaili Yisu on 2018-5-19 at 17:13. I would like to ask the experts: what range of hardness is considered acceptable for the welds of 12Cr1MoVG boiler tubes after heat treatment? The design specifications only mention heat treatment; nothing else is specified in detail.

This also only requires a side view to check the hardness; there’s no need to harden it

Generally, the upper limit is a little over 1/3 of the strength value

Generally speaking, the hardness of the weld is slightly higher than that of the base material
