Re: [MW:30356] G34CrMo4 hardness

This material is NOT for code use, and only limited weldable.

Application shall be used only after proper testing of the welding procedure. (preheating 300-350 degrees centigrade, slow cooling) will offer you 400-500 HV,

PWHT at 600 degrees centigrade (if lower than the tempering temperature) will lower it to 300 - 350 HV 

Be carefull
