GRAIN SIZE AND HARDENABILITY of SAE 4320 forged parts
All material furnished shall be fine grain, ASTM No. 5 or finer.
Hardenability limits for 4320H shall be governed by the methods of specification and the hardenability band shown below per latest issue of the appropriate AISI or SAE publication.
The above chart indicates the hardness values to be expected at three locations on a round specimen depending on section size cooling rate."
EXAMPLE
For a mild oil quench at a Jominy distance of 4/16"", a hardness range of Rc 32-43 could be expected at the surface of a 1.8"" diameter round or at the 3/4 radius location of a 1.0"" diameter round or at the center of a
0.6"" diameter round."
The chart below tabulates hardness values at various depths for certain size rounds. Data is based on End- Quench Hardenability test coupons made from wrought steel stock using a mildly agitated oil quench."

The above hardness values are approximate and should be used for design guidance only. Factors such as chemistry variation,
heat treating parameters, surface condition, grain size, component configuration (cooling
rate), and degree of tempering will affect final hardness."
Note that maximum surface hardness upon straight quenching (not considering surface treatment such as carburizing) this alloy is Rc 41-48
depending on chemistry variation and section size."
MECHANICAL PROPERTIES of AISI 4320 forged bars
"Mechanical properties in the annealed, normalized, and three fully quenched and tempered conditions are tabulated below.
It must be noted that these values are based on standard test coupons and that actual values
vary depending on section size. Desired hardness range and corresponding heat treatment are to be specified on the engineering drawing.
If specific areas of the component require different hardness ranges, that should
also be shown explicitly on the drawing."

Table 3: Mechanical Properties
This alloy is commercially known as a ""carburizing grade"". When carburizing or carbo-nitriding is desired, effective case depth and resultant surface hardness range are to be clearly specified on the engineering drawing. As quenched, Rc 63- 65 hardness is achieved but should be tempered to the desired hardness range (e.g., Rc 60-63, Rc 58-62, Rc 55-60).Core hardnesses and other properties will vary depending on degree of tempering."
Times and temperatures of heat treatment must be consistent with standard heat treating practices to obtain proper microstructure, case depths (when applicable), enhance grain refinement and avoid decarburization or over carburization." Cooling from the tempering temperatures must be rapid enough to avoid temper embrittlement in the 450oF - 800oF range. (A loss in toughness or impact strength occurs when heating or cooling slowly through this range.)"
Hardness tests should be taken on surfaces from which all foreign matter such as scale and decarburized metal have been removed."
QUALITY / MANUFACTURING PRACTICES of AISI 4320 forged parts
"Material furnished shall be commercially sound and free from external and internal defects that would make it unsuitable for forging, machining or heat treating normally employed in processing. This includes seams,
laminations, cold shuts, incipient melting (""burning""), and excessive non-metallic inclusions. Surfaces shall be free of high temperature scale."
Remnant as-case dendritic pattern or alloy segregation is undesirable in hot rolled or forged products. This should not be found in critical stress areas due to reduced mechanical properties and can pose machinability
problems. Areas considered as critical may be indicated on the engineering drawing."
All material furnished must be fully killed. The material may be subsequently processed by vacuum degassing, argon stirring, vacuum arc or electroslag remelting, controlled cooling, etc.
Except as noted above or unless otherwise specified on the purchase order, all material furnished shall be in accordance with the AISI and ASTM standard practices.
In cases not covered by specific standard practices, the product furnished shall be in accordance with accepted trade practices.
PACKAGING AND LOADING of finished AISI 4320 forged parts
All material should be bundled and loaded in accordance with the recommended standard practices defined in the contract with Purchaser.
All shipping notices shall include the Customer's Purchase Order Number.
IDENTIFICATION of finished SAE 4320 forged bars
Material shall be tagged as per standard practices of AISI and ASTM. All tags must show the following information:
Customer's Name and Purchase Order Number
Supplier's Name
Grade and Specification -
Size and Length of forged Plates, Bars, Rounds, Tubing and Pipe
Weight of Lift
Heat Number and original producing mill name
CLients Color Code - Gray and White - to be painted on one end of each piece.
Clients Color Code - Brown and Yellow and Black - to be painted on one end of each piece.
All AISI 4320 forged bars three inches in diameter or equivalent cross section or larger, all hot forged and rough machined rounds, and all semi-finished product shall be die stamped with the heat number on one end only."
AISI 4320 Forged special shapes must have the forging heat code forged or stamped in a location that will not be obliterated by machining or other means. It is advisable for the location of this code to be shown on the
engineering drawing."
