These plates are rolled from highest quality steel, manufactured by the electric furnace process, to meet the rigid standards of the aircraft industry. They are uniform in quality and condition and are free from internal and external defects that would be detrimental to the fabrication or performance of parts.

The plates are produced by rolling on large "sheared plate" mills. As the slab is reduced in thickness, it is cross-worked to produce a quality plate that is sound and dense with excellent properties in both longitudinal and transverse directions.

Applications

N/A Intended for use in the manufacturing of highly stressed aircraft parts requiring good hardenability as well as parts requiring high ultimate tensile strength.

Formability

N/A This material in thicknesses up to 3/4" shall withstand being bent 90° around a diameter equal to its nominal thickness, both perpendicular and parallel to the direction of rolling.

Heat Treating

N/A To develop the highest strength (260,000 psi minimum ultimate) with the best combination of mechanical properties in both transverse and longitudinal directions, the following thermal treatment is recommended:
Normalize—1650°F ±25°
Austenitize—1
725°F minimum for lower strength levels
For lower strength levels, higher tempering temperatures may be used.
