OSTP ALLOY ADJUSTMENT FACTOR Typically the price of stainless steel is comprised of two components, the base price and the Alloy Adjustment Factor (AAF). The base price represents the manufacturers cost for producing the material in a certain size, finish, profile etc. The AAF is a charge for the alloys used (e.g. nickel, molybdenum) to produce the specific grade as this varies considerably according to the grade (and specific composition) that the customer has specified.
