A post weld heat treatment at 1040° C – 1090° C, spheroidizes the ferrite present in type 347 SS weldments, which effectively reduces sigma formation. Typically, the energy used for process heating accounts for 2% to 15% of the total production cost. An intermediate hold at 595° C is recommended for those weldments to relieve residual stresses and to reduce the susecptibity to cracking during post weld heat treatment. endobj Include: a.
