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. DF or smal diameter or thin walls, or both, tubing, where many drawing passes are required, a carbon maximum of 0. 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.

These features should be recognized in the asttm of these materials. The steel shall conform to the following tensile properties: BCalculated elongation requirements shall be rounded to the nearest whole number. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Most of these grades are commonly known as the “straight-chromium” types and are characterized by being ferromagnetic.

Several mechanical tests shall be conducted, namely: Grade TP is used primarily for hot-water tank service and does not 2a68 post-weld heat treatment to prevent attack of the heat affected zone. A number in parentheses indicates the year of last reapproval.

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. Most of these grades are commonly known as the “straight-chromium” types and are characterized by being ferromag-netic. The tubes shall have a hardness number that will not exceed the prescribed Brinell and Rockwell hardness values.

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. 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.
