430FR Stainless Steel Machining

Stainless Steel Alloy 430 FR Machined Parts

Cox Manufacturing has a reputation for machining quality parts from 43FR Stainless Steel. We can machine intricate parts on our CNC Swiss machines and CNC turning centers.

Stainless steel alloy 430FR is a free-machining solenoid quality alloy, ideal for parts that require corrosion resistance and high electrical resistivity. It has excellent corrosion resistance in fresh water, gaseous, moderately acidic, and low chlorine environments. 430FR’s high silicon levels give it increased hardness, decreased deformation from impact, and increased magnetic characteristics.

430FR has a machining cost factor of 2.7 when compared to steel 12L14. It is not ideal for welding due to its high sulfur content, and does not respond to heat treatment. 430FR withstands moderate cold work and can be forged and annealed.

Industries & Applications

  • Solenoid valves
  • Injectors
