Hot working in any but the annealed condition can affect the strength level. Not applicable aa711 this alloy. For high strength over ksi the alloy should first be normalized at F prior to heat treatment.
Machining is best done with this alloy in the annealed or normalized and tempered condition. This specification covers cast carbon and alloy steel ingots and strand castings, semi-wrought ingots and strand castings, and rolled or forged blooms, billets, and slabs for steel forging stock.
It is known for its toughness and capability of developing high strength in the heat treated condition while retaining good fatigue strength. AISI is considered to be a “through hardening” steel such that large section sizes can still astmm heat treated to high strength.
Link to Active This link will always route to the current Active version of the standard. Modulus of Elasticity Tension. Forging may be done in the range of F max. Blooms and billets may be square, round, octagonal, or rectangular in section; slabs are rectangular. Although no invariable rule prevails between the terms blooms and billets, and they are frequently used interchangeably, the following size distinctions are in general use.

ASTM A/AM – 17 – Standard Specification for Steel Forging Stock
This abstract is a brief summary of the referenced standard. AISI is a heat treatable, low alloy steel containing nickel, chromium and molybdenum.
Typical applications are for structural use, such as aircraft landing gear, power transmission gears and shafts and other structural parts. Remember me for one month. 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. Heat treatment for strengthening w711 done at F followed by an oil quench. If, however, such defects do occur, surface conditioning, cutting, or parting may be performed by scarfing or flame-cutting.
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. A full anneal may be astn at F followed by controlled furnace cooling at a rate not faster than 50 F per hour down to F. If, however, such defects do occur, surface conditioning, cutting, or parting may be performed by scarfing or flame-cutting. Although no invariable rule prevails between the terms blooms and billets, and they are frequently used interchangeably, the following size distinctions are in general use.

Consult the alloy supplier in regard to hot working. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. From F aastm may be air cooled. The alloy may be cold worked, in the annealed condition, by conventional methods and tooling.
Final products shall be free of injurious surface imperfections. This specification covers cast carbon and alloy steel ingots and strand castings, semi-wrought ingots and strand castings, and rolled or forged blooms, billets, and slabs for steel forging stock. They shall apply only when specified by the purchaser. Distributors will offer small quantity buys while mills will asgm only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required This material is stocked primarily in Bar Products by 59 distributors but is also available to a lesser extent in Flat Rolled Products, Forging Products, Tubular Products, Wire Products, Fasteners, Piping Components, and Structurals.
Heat and product analyses shall be carried out to evaluate conformance of steel specimens to chemical composition requirements. Print 1 2 3 4 5 page sstarting a71 page current page.
See “Tempering” for strength levels. Preheat and post heat weld procedures should be followed when welding this alloy by established methods. Combining values from the two systems may result in non-conformance with the standard. Do NOT temper the alloy if it is in the – ksi strength range as tempering can result in degradation of impact resistance for this level of strength.
Final products shall be free of injurious surface imperfections. Search book title Enter keywords for book title search.
