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.

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.

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.
