Expert Machining Tips

1

Allow extra lead time vs aluminum (2-3x longer machining)

2

Specify 304L for welded assemblies

3

Standard tolerances unless critical dimensions identified

Common Parts Made

Food equipment prototypes

Medical device validation

Chemical vessel test parts

Machining Challenges

  • Longer lead time than aluminum
  • Higher machining cost
  • Surface finish may not match production (polished/electropolished)
