ASTM A Stainless Steel tubing standard download

The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Grade TP is used primarily for hot-water tank service and does not require post-weld heat treatment to prevent attack of the heat affected zone. These features should be recognized in the use of these qstm. These features should be recognized in the use of these materials.

Combining values from the two systems may result in nonconformance with the specification. This guide covers standard specification for a number of grades of nominal-wall-thickness, welded ferritic and martensitic stainless steel tubing for general corrosion-resisting and high-temperature service.

For lengths over 24ft[7. This standard is issued under the fixed designation A ; the number immediately a628 the asrm indicates the year of original adoption or, in the case of revision, the year aatm last revision. Most of these grades are commonly known as the “straight-chromium” types and are characterized by being ferromagnetic. On such sizes a variation in wall thickness of Grade TP is used primarily for hot-water tank service and does not require post-weld heat treatment to prevent attack of the heat affected zone.

Two of these grades, TP and UNS S Table 1are amenable to hardening by heat treatment, and the high-chromium, ferritic alloys are sensitive to notch-brittleness on slow cooling to ordinary temperatures.
