When 16Mo3 welding with others it needs preheat because materials are different. and after welding in the weld should also be insulated for 30 minutes.
16mo3 steel, Mn is also an important component of steel, it has a great impact on the metal seam.
16mo3 steel plate when the Mn content <0.05% when the weld metal toughness is very high; 16mo3 steel when the Mn content> 3% and then very brittle;
Application:
16Mo3 is alloy special steel pipe for pressure purposes, 16Mo3 seamless pipe is applied for manufacturing pipeline, vessel, equipment, pipe fittings and steel structure.
