Characteristics of Welding Heat Affected Zone of Refractory Steel
Weld Heat Affected Zone of Steel That Is Not Easy to Harden
Introduction
In the welding process, the temperature of the heat affected zone (HAZ) will be higher than that of the other parts of the material, so it will lead to a change of the mechanical properties in the zone of influence. For som......
