- SAE9310 Bar Stock imported from Japan to ensure the purest steel grades
- All MFactory components are Forged. We do not use inferior Cast or Billet processes. Forged components are upto 30% stronger & tougher than the equivalent "Billet" component. Click here for further details
- Advanced material processing, heat treatment & finishing techniques offer superior strength, durability and quality
- Primary Heat Treatment: After the forged parts come off the press, they are Normalized and Annealed to relieve residual stresses and make them machine workable
- Machining: After the forged blanks are completed, we use Industry-leading Multi-Axis CNC and CAM equipment to machine the parts
- Secondary Heat Treatment: State-of-the-art Case Hardening procedure achieved via computer-controlled Gas Carburization and Quenching
- Double-Tempering: A superior heat treatment technique used to decrease the brittleness and increase the toughness of our parts
- Surface Grinding: Through the use of our state-of-the-art diamond grinding machines, we ensure all parts are smooth, precise and free of burrs
- Super Sub-Zero Processing: An advanced treatment technique whereby the parts are cryogenically hardened at -300°F, realigning the steels crystalline structure for maximum strength, then heat tempered again for a 3rd time to ensure maximum toughness (resistance to fracture)
- Micro-Peening: Our final treatment stage, the parts are subject to a high speed shot blast with our proprietary micro media, creating a super smooth surface
