SS 347 Flange (UNS 34700) offers higher crawl and stretch crack properties than Type 304 and, especially, Type 304L which may likewise be considered for exposures where refinement and intergranular consumption are concerns. SS 347H Flanges (UNS 34709) is somewhat harder than that of evaluation 304 steel.

However, the hardenability of this steel can be minimized by the utilization of consistent positive encourages and moderate velocities. These spines are fundamentally utilized as a part of high temperature situations where imperviousness to refinement is vital, thus forestalling intergranualr consumption at lower levels.
