Bars shall be suppled in the solution treated condition with a turned or centerless ground finish.

Hast X shall be solution heat treated by heating within the range 2100 to 2150 °F, holding at the selected temperature within ±25 °F for a time commensurate with cross-sectional thickness but not less than 20 minutes, and cooling at a rate equivalent to an air cool or faster.

Hardness shall not exceed a 241 HB.

Stress rupture properties --- A tensile specimen, maintained at 1500 °F ± 3 ° while a load sufficient to produce an initial axial stress of 15.0 ksi or higher is applied continuously, shall not rupture in less than 24 hours.

Our common stock sizes from .625” to 2.75” diameters.
