Alloy Steel NAS74N Workability
Attention should be paid for the strength behavior of NAS74N which abruptly increases below 1000℃ in spite of the lower strength than Type 304 at high temperatures. Solution annealing should be carried out after hot working. Attention has to be also paid for the behavior of cold workability because of the higher proof stress along with the lower elongation than Type 304.
