Re: [MW:10282] Effect of ferrite element on 347H material

in stainless steel there is a chances of solidification cracking
during solidification of weldment. ferrite can avoid this
solidification cracking if it is in limit. limit of ferrite depends on
stainless steel application. generally it is good to have 2 to 4 FN in
stainless steel. above this range it may reduce ur toughness value
