The Alloying Elements Added in Micro Amounts to the Steels are

Vanadium (V)

Columbium (Cb)

Titanium (Ti)

Nitrogen may also be Added with These Elements to Further Enhance Properties.

To Develop Maximum Strength and Hardness Capabilities, Special Thermal Processes may be Employed: Accelerated Cooling after Forging. Microalloyed Steels are Used where Strength and Hardness are the Primary Needs. This Permits the Application of Microalloy Forged Product, Thus the Elimination of Conventional Quenching & Tempering Operations. In Many Operations, Machine-ability of the Microalloyed Product may be Better than the Quenched & Tempered Product.

Microalloy Products are Fully Air Quenched and are in the Blackened State (1100ºF) as they Leave the Conveyor. All Runs are Tested for Conformance to the Specified Hardness. S.P.C. Charting of Hardness Results are Performed and Maintained as Part of the Quality Assurance Program at Mercer Forge Corporation. Capability Studies Show Most Products to have a Very Tight Range, with Cp’s in the 2.00 and 2.20 Area, and Cpk’s at 1.65 .

A Wide Variety of Drive Shaft Components (from 10 to 40pounds) have been Processed. These Parts have been Forged from Rounds 3″ to 4″ in Diameter and from 4″ Round Corner Squares.

Base Chemistry for Mercer Forge Corporation’s Microalloyed Steel has been 1141 Grade, with a Vanadium Addition. Other Grades have been Microalloyed and Processed Successfully on an Experimental Basis. Microalloy Conveyance Equipment at Mercer Forge Corporation has been Constructed to Allow for a Variety of Speeds and Cooling Characteristics: To Meet a Wide Variety of Customer’s Needs.
