Material Scope

Documented Material Machining Experience

Experienced with a wide variety of industrial metals, with specialized focus on stainless steel and mild steel grades.

Stainless Steel Machining

Stainless steels present unique machining challenges such as work hardening and high heat generation. Our experience across tooling grades, coolant application, and cutting dynamics ensures consistent surface finish and dimensional tolerances.

  • Austenitic & Martensitic stainless grades
  • Specialized valve plugs in various SS grades
  • High corrosion resistance components

Mild Steel Machining

Mild steel alloys are extensively machined for industrial brackets, automobile parts, bushings, and shafts. High chip-removal rates and rapid CNC cycle times ensure cost-effective production runs.

  • Low & medium carbon steel grades
  • Automobile turned and milled parts
  • Flanges, pins, collars, and housing blocks
