VT machining offers CNC Turning for T301 Stainless Steel (301 temper-rolled strip (JIS SUS301-CSP)), typically supplied temper-rolled strip. Supplied in pre-hardened spring tempers; parts are blanked/etched to shape rather than heavily machined.
CNC Turning Notes for T301 Stainless Steel
On the lathe T301 Stainless Steel needs chip-breaker inserts and constant chip load to avoid long, stringy swarf.
For estimating, a 100 × 100 × 10 mm block of T301 Stainless Steel weighs about 0.79 kg.
