BOvality provisions 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. A number in parentheses indicates the year of last reapproval.

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

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. 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.
