10 HEUCAL COIL INSERT

10.1 Material

Chemical composition of the inserts is austenitic corrosion-resistant (stainless) steel within the limits of Table 2.

10.2 Properties

10.2.1 TensIle Strength. Wire, before coiling into inserts, shall have tensile strength not lower than 1035 MPa, determined in

accordance with ASTM A 370.

10.2.2 Bending. Wire shall withstand, without cracking, bending in accordance with ASTM E 290 at room temperature through an angle of 180 deg around a diameter equal to twice the cross-sectional dimension of the wire in the plane of the bend.

10.2.3 Workmanship. The formed wire shall be of uniform quality and temper; it shall be smooth, clean, and free from kinks,

waviness, splits, cracks, laps, seams, scale, segregation, and other defects that may impair the serviceability of the insert.

10.3 Coatings

10.3.1 Dry Film Lubricant Coating. At the option of the user, dry film lubricant coating an be applied to helical coil inserts. The coating shall meet the requirements of paras. 10.31.1 and 10.3.1.2. The color of dry film—lubricated inserts is dark gray to

black.

10.3.1.1 Material. The lubricant shall meet the requirements of Aerospace Standard SAE AS5272, Type I, Lubricant, Solid Film Heat

Cured, and Corrosion Inhibiting.

10.3.1.2 Thickness. The coating shall be uniformly deposited on the insert with the minimum thickness being complete coverage.
