| HAYNES® 230® alloy is approved
for ASME Vessel Code Section I and Section Vlll Division 1 construction
to 1650°F (899°C) under Code case No. 2063. Allowable stresses
are reprinted here by permission of the ASME.

| NOTE (1)
Due to the relatively low yield strength of this material, these higher stress values were established at temperatures where the short time tensile properties govern to permit the use of these alloys where slightly greater deformation is acceptable. These higher stress values exceed 67%, but do not exceed 90% of the yield strength at temperature. Use of these stresses may result in dimensional changes due to permanent strain. These stress values are not recommended for flanges of gasketed joints or other applications where slight amounts of distortion can cause leakage or malfunction. |

HAYNES 230 alloy exhibits significant design strength advantages over
other ASME vessel code covered materials for Section Vlll Division 1 construction
at temperatures up to 1650°F (899°C).
