The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Grade TP is used primarily for hot-water tank service and does not require 2a68 heat treatment to prevent attack of the heat affected zone. 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. Work Item s – proposed revisions of this standard.

Within the text, the SI units are shown in brackets. Link to Active This link will always route to the current Active version of the standard. Combining values from the two systems may result in nonconformance with the specification. BCalculated elongation requirements shall be rounded to the nearest whole number. These features a28 be recognized in the use of these materials. 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.

Most of these grades are commonly known as the “straight-chromium” types and are characterized by being ferromag-netic. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

The tubes shall have a hardness number that will not exceed the prescribed Brinell and Rockwell hardness values. Small outside diameter tubes are defined as those less than 0. Several mechanical tests shall be conducted, namely: It is informational only and not an official part of the standard; the full text of aatm standard itself must be referred to for its use and application.

AFor longitudinal strip tests a deduction of 0. The following table gives the computed minimum values. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order. The number of tubes in a lot heat treated by the continuous process shall be determined from the size of the tubes. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
