VT machining offers CNC Milling for 202 Stainless Steel (UNS S20200 / 1.4373), typically supplied annealed. Slightly more Ni than 201, so better formability; still below 304 in corrosion resistance.
CNC Milling Notes for 202 Stainless Steel
202 Stainless Steel mills well with conventional strategies; finishing passes are planned to meet flatness and finish callouts.
For estimating, a 100 × 100 × 10 mm block of 202 Stainless Steel weighs about 0.78 kg.
