VT machining offers CNC Punching for 201 Stainless Steel (UNS S20100 / 1.4372 / SUS201), typically supplied annealed. Low-nickel substitute for 304; manganese raises strength but lowers corrosion resistance and work-hardens faster.
CNC Punching Notes for 201 Stainless Steel
201 Stainless Steel punches cleanly with standard clearance; minimum hole diameter is about the sheet thickness.
For estimating, a 100 × 100 × 10 mm block of 201 Stainless Steel weighs about 0.78 kg.
