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.

The purchaser shall furnish the manufacturer with details of the desired heat treatment for the test coupons, including temperatures, times, and cooling rates. The Forged Steel should be produced primarily by either electric-furnace, basic oxygen, vacuum-induction VIMor open-hearth melting process.

The primary melting may x788 separate degassing or refining and may be followed by secondary melting, using electro slag ESR or vacuum arc remelting VAR. Examples for several elements shown below: This suffix shall not be removed until the material speci? Cooling Prior to Heat Treatment 7.

This analysis shall be made from a test sample preferably taken during the pouring of the heat and shall conform to the requirements of the product speci? Repair welding shall not be allowed unless permitted by the product specification. An example of the determination of a weighted average analysis for an ingot made from a three-heat combination pour with varying weights and chemistry involved in each heat is shown below: The steel producer shall remove asgm transition material by any established procedure that positively separates the grades.

ASTM A covers the standard specification for stainless steel forgings. This abstract is a brief summary of the referenced standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Wrought Carbon Steel Wheels. A number in parentheses indicates the year of last reapproval. The steel is forged by any of these three classes based on forging temperature: ASTM A specification applies to steel forgings for general use. Charpy Impact Tests S In modern times, industrial forging is done either with presses or with hammers powered by compressed air, electricity, hydraulics or steam. Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power in the production and working of iron in the 12th century which allowed the use of large trip hammers or power hammers that exponentially increased the amount and size of iron that could be produced and forged easily.

The area shall be taken in the most unfavorable location relative to the indications being evaluated. After forging, specimens shall be allowed to cool prior to reheating for heat treatment. Rough Machining and Boring S The evacuation system shall be capable of reducing the pressure surges, which occur each time a new portion of steel is admitted to the vessel to increasingly lower levels, until a blank-off pressure usually less than ?

Fracture Toughness Test S7. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

Limitations on the application of the allowances in Table 1 may be made in the product speci? Work Item s – proposed revisions of this standard.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Additional terms and wording more applicable to forgings are as noted in this section. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

This standard has been approved for use by agencies of the Department of Defense. Combining values from the two systems may result in non-conformance with the standard.
