MIL-T-6737 (T 321)

Tubing, Steel, Corrosion and Heat Resistant (18-8 Stabilized), Welded. Annealed.

Type 321 and 347 tubing intended   use in the manufacture of exhaust stacks, manifolds, blast tubes,  ring collector  and similar  applications where a weldable corrosion and heat resisting steel is required or for use at 800º – 1500°F.

MIL-T-6845 (T 304)

Tubing, Steel, Corrosion Resistant 304) Aerospace Vehicle Hydraulic ³/  Hard, Seamless, Weldsd Drawn.

Intended for use in high pressdre hydraulic and pneumatic systems in which corrosion resistant materials are required. The tubing is not suitable for use in applications assembled by weldin   or brazing or exposed to temperatures higher 800°F.,   because  of   impaired   resistance  to corrosion, where subsequent anneal not possible.

MIL-T-8504 (T 304)

Tubing, Steel, Corrosion Resistant 18-8) Annealed, Aircraft Hydraulic Seamless, Welded.

Intended for use in high pressure hydraulic and pneumatic systems in which corrosion resistant materials are required. This tubing is of lower strength and higher ductility than tubin  Speci- fication  MIL-T-6845.  May be used to MIL-T-6845 tubing but heavier wall thicknesses must be used. Same qualifications regarding welding, brazing & temperature.

MIL-T-8506 (T 304)

MIL-T-8808
(T 321)
(T 347)

Tubing, Steel, Corrosion Resistant (18-8 Stabilized), Aircraft Hydraulic Quality. Annealed. Seamless, Welded  &  Drawn.

Intended for use in high hydraulic and pneumatic systems where and heat resistance are required and in which welding or brazing may be involved during fabrication. Resists oxidation at temperatures to 1200°F., but is useful at that  temperature  only when  stresses are low.
