Upset Forging: High-Strength Headed and Flanged Metal Components

How CIC Specializes in Upset Forging Technology

At Custom Industrials Company (CIC), our upset forging process produces headed fasteners, flanged shafts, bolts, studs, and custom axial-profile components with superior mechanical properties and excellent material utilization. By axially compressing hot bar stock to redistribute metal and form enlarged cross-sections, upset forging creates refined grain flow that maximizes tensile strength, shear resistance, and fatigue performance — ideal for high-integrity fastening, coupling, and structural applications across automotive, industrial, and energy markets.

What Is Upset Forging?

Upset Forging is a precision manufacturing process that delivers:

  • Axial compression of hot bar stock to form enlarged head or flange features
  • Grain flow oriented around the head geometry for maximum strength
  • Superior tensile and shear strength vs. machined fasteners
  • Excellent material utilization with minimal scrap
  • Net-shape or near-net-shape head geometry reducing machining
  • Available in standard and custom head configurations
  • Broad alloy coverage from carbon steel to stainless and specialty alloys

Upset Forging FAQs

What is upset forging and how is it different from standard forging?
Upset forging specifically displaces metal axially to enlarge cross-sections at specific locations — most commonly forming bolt heads, flanges, and other enlarged features on shafts or fasteners. The controlled grain flow around the head greatly exceeds the strength of machined alternatives.
Are upset forged fasteners stronger than machined ones?
Yes. Upset forging aligns grain flow around the head geometry rather than cutting through it as machining does. This results in significantly higher tensile, shear, and fatigue strength — critical for high-integrity bolted joint applications.
What head configurations are available?
CIC can produce hex, square, round, countersunk, and custom profile head geometries. Flanged configurations including upset flanges, stub flanges, and coupling flanges are also available. Contact our engineering team with your specific geometry requirements.
What alloys can be upset forged?
We upset forge carbon steels, alloy steels, stainless steels, aluminum alloys, titanium alloys, and many specialty materials. Heat treatment after forging is available to achieve specific mechanical property requirements.
Can CIC provide finished machined upset forgings?
Yes. CIC's in-house machining capabilities can produce fully finished upset forgings including threading, turning, drilling, and milling — delivering complete components ready for assembly.
