Therefore, the addition of strong adtm forming elements, those with a stronger affinity for nitrogen than Cb and V, as deoxidation agents, interferes with these high-temperature strengthening mechanisms.

Heat treatment shall consist of normalizing and tempering for Grade C12A and tempering for all other grades. The two elements are more effective in combination. Failure to comply with the general requirements of Speci?

Note 2 — The grades covered by this specification represent materials that are generally suitable for assembly with other castings or wrought steel parts by fusion welding. Originally published as A — 39 T. Heat treatments shall be performed after castings have been allowed to cool. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

General Conditions for Delivery 3. Note 2—The grades covered by this specification represent materials that are generally suitable for assembly with other castings or wrought steel parts by fusion welding. Selection will depend on design and service conditions, mechanical properties, and the high-temperature and corrosion-resistant characteristics Note 3.

Steels shall undergo tension test, and shall conform to the following mechanical requirements: When methods involving high temperature are used in the removal of discontinuities, castings shall be preheated to at least the minimum temperatures in Table 3.

The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. This specification covers steel castings, martensitic stainless steel and alloys steel castings for valves, flanges, fittings, and other pressure-containing parts intended primarily for high-temperature and corrosive service.

Additional alloy steels that may better fulfill certain types of service will be considered for inclusion in this specification by the committee as the need becomes apparent.

Since these grades possess varying degrees of suitability for high-temperature and corrosion-resistant service, it is also the responsibility of the purchaser to determine which grade shall be furnished, due consideration being given to the requirements of the applicable construction codes.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. It is not intended to imply that these grades possess equal degrees of weldability; therefore, it is the responsibility of the purchaser to establish for himself a suitable welding technique.
