Looking for a Hardfacing Consumable for Pressure Piping.
Looking for a Hardfacing Consumable for Pressure Piping.
(OP)
Hi,
I need to hardface overlay the ID of a 316L pipe that that will be used in a B31.1 piping system. I am looking for a consumable that will achieve a hardness of approximately 40HRC and be crack free and meet the requirements of ASME IX Table QW-453.
The design condition are 300 psig and 300°F
Is there such a consumable on the market.
Thanks

I understand about check cracking and stellite 6 cracking but I want to avoid ANY cracks propagating into the HAZ or base material. Hardfacing is most often used for abrasive resistance like digger blades etc, where cracking is not a problem. Cracking becomes a real problem when dealing with pressure piping or vessels.
Thanks
