SUPPLEMENTARY REQUIREMENTS

Standardized supplementary requirements for use at the option of the purchaser are listed in

Specification A 6/A 6M. Those that are considered suitable for use with this specification are listed by title:

S5. Charpy V-Notch Impact Test.

In addition, the following optional supplementary requirements are also suitable for use with this specification.

S32. Single Heat Bundles.

S32.1 Bundles containing shapes or bars shall be from a single heat of steel.

S78. Maximum Carbon Equivalent.

S78.1 This material shall be supplied with a maximum  carbon equivalent value of 0.55 % or to a lower value specified in the purchase documents. This value will be based on heat analysis. The required chemical analysis as well as the carbon equivalent shall be reported.

S78.2 The carbon equivalent shall be calculated using the following formula:

CE = C + (Mn + Si)/6 + (Cu + Ni)/15 + (Cr + Mo + V + Cb)/5

S79. Maximum Tensile Strength.

S79.1 The maximum tensile strength shall be 90 ksi [620
