| MIL-T-5695 |
Tubing, Steel, Corrosion Resistant, (T91) Cold Drawn (1/2 or 1/4 Hard) Smls or W&D. |
Intended for use in the fabrication of aircraft structural parts requiring a high degree of resistance to corrosion. |
| MIL-T-6737 |
Tubing, Steel, Corrosion and Heat Resistant (18-8 Stabilized), Seamless.Annealed. |
Type tubing intended for use in the manufacturer exhaust-stacks, manifolds, blast tubes, ring collectors and similar applications where a weldable corrosion and heat resisting steel is required or for use at 8000 – 1500?F. |
| (T91) |
| MIL-T-6845 |
Tubing, Steel, Corrosion Resistant (T91) Aerospace Vehicle Hydraulic System. 1/8 Hard, Seamless, Seamless & Drawn. |
Intended for use in high pressure hydraulic and pneumatic systems in which corrosion resistant materials are required. The tubing is not suitable for use in applications assembled by welding or brazing or exposed to temperatures higher than 800?F, because of impaired resistance to corrosion, where subsequent anneal not possible. |
| (T91) |
| MIL-T-8504 |
Tubing, Steel, Corrosion Resistant (18-8) Annealed, Aircraft Hydraulic System. Seamless. |
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 tubing to Specification MIL-T-6845. May be used to replace MIL-T-6845 tubing but heavier wall thicknesses must be used:Same qualifications regarding welding, brazing & temperature. |
| (T91) |
| MIL-T-8506 |
Tubing, Steel, Corrosion Resistant, (T91) Annealed, Seamless. |
Intended for use in the fabrication of aircraft parts requiring a high degree of resistance to corrosion. Not to be used in high pressure hydraulic control systems. |
| (T91) |
| MILT 8606 |
Tubing, Steal, Corrosion Resistant (18-8 Stabilized). Annealed. Seamless & Drawn. |
Intended for use in applications which require a high degree of resistance to corrosion or to temperatures in the range of 800?F-1500?F. or in applications which involve welding. Suitble for use in tank-automotive equipment for hydraulic and mechanical applications. |
