Solution Treatment (Annealing) - heat to 950-1120°C and cool rapidly for maximum corrosion resistance.
Stabilising - heat to 870-900°C for 1 hour per 25mm of thickness and air cool. Stabilisation is recommended for most severe service conditions (above 425°C) and particularly for material annealed at the upper side of the annealing temperature range.
Stress Relief - Heat to 700°C for 1 to 2 hours and air cool.
These grades cannot be hardened by thermal treatment.
Excellent weldability by all standard fusion methods, both with and without filler metals. AS 1554.6 pre-qualifies welding of 321 and 347 with Grade 347 rods or electrodes; high silicon version of 347 is also pre-qualified for welding of 321.
