Such cycles shall be followed by tempering within the temperature limits required by the material speci? The primary melting may incorporate separate degassing or re?

The results of the method used shall conform to the requirements of the product speci? Details of heat and product analyses for the evaluation of chemical composition are thoroughly discussed. It is desirable that two of the specimens will have values of cleavage fracture above the value of n, and two will have values below this level.

After forging, specimens shall be allowed to cool prior to reheating for heat treatment. The last asm version of this historical standard is referenced on www.

The outside diameter may be contoured if required. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Supplementary Requirements S5 or S6, concerning straightening of forgings, may be used. Straightening of Forgings S5.

Blocks shall meet one of the following requirements: Materials shall be produced primarily by either electric-furnace, basic oxygen, vacuum-induction VIMor open-hearth melting process. The reference blocks shall be fabricated in accordance with the procedures of Practice E Historical Version s – view previous versions of standard.

These and other limitations or tests may be performed by agreement between the supplier and purchaser. The longitudinal axis of the specimen shall be parallel to the length of the hub, as shown in Fig.


It is necessary to make this determination to ensure that each Furnace HeatA Weight, tons 25 50 50 B A B element in the official chemistry is represented by proportion to its amount in each individual furnace heat. Ultrasonic Examination from Bore Surface S Cooling Prior to Heat Treatment 7. The primary melting may incorporate separate degassing or refining and may be followed by secondary melting, using electro slag ESR or vacuum arc remelting VAR. The heat analysis of the remelted ingot shall be represented by a weighted average see Annex A2 of the individual chemical analyses for each zone.

Combining values from the two systems may result in non-conformance with the standard.

Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Charpy Impact Tests S Tension and hardness tests shall be conducted to evaluate mechanical properties such as the percentage 7a88 elongation and reduction of area.

The acceptance of any such additional requirements shall be dependent on negotiations with the supplier and must be included in the order. 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.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Heat Analysis for Remelted Ingots S This standard has been approved for use by agencies of the Department of Defense.
