Applications

Applications of Carbon Steel

  • AISI 1018

    Carbon steel’s stable machinability enables CNC production of engine brackets and chassis mounting interfaces with consistent dimensional accuracy.

  • AISI 1045

    Used for CNC-machined control arms and linkage blocks, balancing strength, repeatability, and efficient material removal rates.

  • AISI 1060

    Ideal for shafts and coupling interfaces, where carbon steel supports high torque loads and precise machining tolerances.

  • AISI 4130

    Supports manufacturing of structural reinforcements and crossmembers requiring rigidity, vibration resistance, and scalable production consistency.

FAQs

Frequently Asked Questions
