Land Use and Development. Search book title Enter keywords for book title search. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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.
Not applicable to this alloy. 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.

This abstract is a brief summary of the referenced standard. Combining values from the two systems may result in non-conformance with the standard. 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. Abstract 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.
See “Tempering” for strength levels.

Bend radii should be 3t or greater. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. Copyright Compu-tecture, Inc. The alloy can be fusion or resistance welded. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
The alloy will harden by cold working or by heat treatment — see “Heat Treatment” and “Tempering”. ASTM does not give any warranty express sstm implied or make any representation that the contents of this abstract are accurate, complete or up to date.
AISI is a heat treatable, low alloy steel containing nickel, chromium and molybdenum.
Blooms and billets may be square, round, octagonal, or rectangular in section; slabs are rectangular. Print 1 2 3 4 5 page sstarting from asgm current page. Final products shall be free of injurious surface imperfections.

The alloy may be cold worked, in the annealed condition, by a7711 methods and tooling. If, however, such defects do occur, surface conditioning, cutting, or parting may be performed by scarfing or flame-cutting.
Please login to your authorized staff account to use this feature. Typical applications are for structural use, such as aircraft landing gear, power transmission gears and shafts and other structural parts.
Blooms and billets may be square, round, octagonal, or rectangular in section; slabs are rectangular. Enter your account email address to request a password reset: Materials shall be manufactured and furnished in a condition that can withstand, for an indefinite time, exposure to all climatic conditions without w711 any external or internal cracks.
Hot working in any but the annealed condition can affect the strength level. For strength levels in the – ksi range temper at F. Enter your personal account email address to request a password reset: It has w711 ductility.
A full anneal may be done at F followed by controlled furnace cooling at a rate not faster than 50 F per hour down to F. It is known for its toughness and capability of developing high strength in the heat treated condition while retaining good fatigue strength. 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. Heat and product analyses shall be carried out to evaluate conformance of steel specimens to chemical composition requirements.
For high strength over ksi the alloy should first be normalized at F prior to heat treatment. It can be bent or formed by spinning or pressing in the annealed state.
Consult the alloy supplier in regard to hot working. The temperature for tempering depends upon the strength level desired. Preheat and post heat weld procedures should be followed when welding this alloy by established methods.
