ASTM A788 Stainless Steel Forged Fittings Suppliers

Cast shapes produced by a continuous casting process, without subsequent work, are considered to be ingots for the purposes of this speci? Forgings of large size are commonly used by industrial equipment and machinery such as steel, textile, paper, power generation and transmission, chemical and refinery industries.

Additional terms and wording more applicable to forgings are as noted in this section. Dimensions and Finish Repair welding shall not be allowed unless permitted by the product specification.

These elements are considered as incidental and may be present to the following maximum amounts: The acceptance of any such additional requirements shall be dependent on negotiations with the supplier and must be included in the order. Such treatments are intended to simulate post-weld or other treatments to which the forgings will be subjected during subsequent fabrication. Historical Version s – view previous versions of standard.

The reference blocks shall be fabricated in accordance with the procedures axtm Practice E Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
