Weldability :
without limitations - welding is done without heating and subsequent heat treeting
limited weldability - welding is possible under heating up to 100-120 grade and subsequent heat treeting
hard weldability - obtaining the quality welding needs the additional operations:heating up to 200-300 grade; the heat treeting ia annealing
Fabrication Guidance
Forming: excellent; use generous radii and proper lubrication
Machining: use sharp carbide tools, lower speeds, higher feed, abundant coolant
Welding: GTAW/GMAW/SMAW accepted; use stabilized/filler compatible with 321 chemistry; control heat input; post-clean and passivate
