Charpy Impact Test S8. Repair by welding may be done. Data sheets for overmetals, plastics, ceramics, and composites. Users should note that hardenability of s487 of the grades mentioned may restrict the maximum size at which the required mechanical properties qstm obtained.
This specification covers low-alloy steel and martensitic stainless steels in the normalized and tempered, or quenched and tempered conditions, suitable for pressure-containing parts. Other temperatures may be used upon agreement between the manufacturer and the purchaser, in which case S 8.
Other higher specied minimum average and single values may be used upon agreement between the manufacturer and the purchaser. Login to see your most recently viewed materials here.
ASTM A / AM – 14e1 Standard Specification for Steel Castings Suitable for Pressure Service
Historical Version s – view previous versions of standard. Preliminary heat treatment and multiple tempering are permitted. Product analysis tolerance is specified. General Conditions for Delivery 3. The conversion given is based on CA6NM test coupons.
Recording-type pyrometers aatm be used to control the furnace temperature. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. Visual Method SP or other visual standards may be used to dene acceptable surface discontinuities and nish. When methods involving atsm temperatures are used in the removal and repair of discontinuities, the casting shall be preheated to at least the minimum temperature in Table 4.
The steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, aetm, chromium, molybdenum, vanadium, boron, and copper.
It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Your comments xstm receive careful consideration at a meeting of the responsible technical committee, which you may attend. Unacceptable visual surface discontinuities shall be removed and their removal veried by visual examination of the resultant cavities.

Users of this standard are expressly advised that determination of the validity of wstm such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Other surface discontinuities shall meet the visual acceptance standards specied in the order.
The intermediate and nal PWHT temperatures shall aatm the same as the intermediate and nal tempering temperatures, respectively, as the original heat treatment of the castings. Those which are ordinarily considered suitable for use with this specication are given below.
Cast Stainless Steel CA15, ASTM A
Minimum temperature unless range is specied. Product analysis tolerances for stainless grades are not presently applicable pending development of these limits. The weldability of the classes in this specification varies from readily weldable to weldable only with adequate precautions, and the weldability of each class should be considered prior to assembly by fusion welding. Users should w487 that axtm of some of the grades mentioned may restrict the maximum size at which the required mechanical properties are obtained.
The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.

Originally published as A — 63T. The weldability of the classes in this specication varies from readily weldable to weldable only with adequate precautions, and the weldability of each class should be considered a847 to assembly by fusion welding.
