ATPS is a lower carbon version of TP that has a lower tensile strength but improved ductility and fracture toughness. 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.

A number in parentheses indicates the year of last reapproval. Small outside diameter tubes are defined as those less than 0. These features should be recognized in the use of these materials. Two of these grades, TP and UNS S Table1are amenable to hardening by heat treatment, and the high-chromium, ferritic alloys are sensitive to notch-brit-tleness on slow cooling to ordinary temperatures.

Work Item s – proposed revisions of this standard.

ASTM A268 317L Stainless Steel EFW Tubes

The steel q268 conform to the following tensile properties: The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.

Within the text, the SI units are shown in brackets. Most of these grades are commonly known as the “straight-chromium” types and are characterized by being ferromagnetic. Less than 2 in. The steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, aluminum, copper, nitrogen, titanium, and columbium.

S 75[] 60[] 15 AFor longitudinal strip tests a deduction of 0. Within the text, the SI units are shown astmm brackets. Two of these grades, TP and UNS S Table 1are amenable to hardening by heat treatment, asgm the high-chromium, ferritic alloys are sensitive to notch-brittleness on slow cooling to ordinary temperatures.

AThese tolerances apply to cut lengths up to and including 24 ft[7. For lengths over 24ft[7.

On such sizes a variation in wall thickness of The following table gives the computed minimum values. These features should be recognized in the use of these materials.

The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. Combining values from the two systems may result in nonconformance with the specification.

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.

DF or smal diameter or thin walls, or both, tubing, where many drawing passes are required, a carbon maximum of 0. Several mechanical tests shall be conducted, namely: Work Item s – proposed revisions of this standard.
