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. A number in parentheses indicates the year of last reapproval.
Most of these grades are commonly known as the “straight-chromium” types and are characterized by being ferromag-netic. 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.
These features should be recognized in the use of these materials. Grade TP is used primarily for hot-water tank service asrm does not require post-weld heat treatment to prevent attack of the heat affected zone.

Within the text, the SI units are shown in brackets. 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. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order. ATPS is a lower carbon version of TP that has a lower tensile strength but improved ductility and fracture toughness.
CW hen intergranular corrosion testing is specified, the a68 will be Practices Ausing samples prepared as agrred upon between the seller and the purchaser.
