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. A number in parentheses indicates the year of last reapproval. Combining values from the two systems may result in nonconformance with the specification. Two of these grades, TP and A286 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.

The following table gives the computed sstm values.

Several mechanical tests shall be conducted, namely: Active view current version of standard. BCalculated elongation requirements shall be rounded to the nearest whole number. AFor longitudinal strip tests a deduction of 0.

Within the text, the SI units are shown in brackets. On such sizes a variation in wall thickness of BOvality provisions of S 75[] 60[] 15 AFor longitudinal strip tests a deduction of 0.

The tubes shall have a hardness number that will not exceed the prescribed Brinell and Rockwell hardness values. 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. This standard is issued under the fixed designation A ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

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. This abstract is a brief summary of the referenced standard. The steel shall conform to the following tensile properties: Historical Version s – view previous versions of standard.

Most of these grades are commonly known as the “straight-chromium” types and are characterized by being ferromag-netic. 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.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. 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.

The steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, aluminum, copper, nitrogen, titanium, and columbium. 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.

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

Small outside diameter tubes are defined as those less than 0. These features should be recognized in the use of these materials. Link to Active This link will always route to the current Active version of the standard. These features should be recognized in the use of these materials. ATPS is a lower carbon version of TP that has a lower tensile strength but improved ductility and fracture toughness. Within the text, the SI units are shown in brackets. For lengths over 24ft[7.
