ASTM A Martensitic Stainless Steel Bars_百度文库
This specification is expressed in both inch-pound units and SI units; however, unless the purchase order or contract specifies the applicable M specification designation SI unitsthe inch-pound units shall apply. This specification covers hot-finished and cold-finished martensitic chromium steel bars for high-temperature service. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
When the visual estimation method indicates the delta ferrite content is greater than the allowed limit, the manufacturer may employ Test Method E for determining the acceptability of the lot. Link to Active This link will always route to the current Active version of the standard. Atm values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
