VT machining offers CNC Bending for 17-4 PH Stainless Steel (UNS S17400 / 1.4542 / SUS630), typically supplied condition A or H900-H1150. Can be finish-machined in Condition A then aged with minimal distortion.
CNC Bending Notes for 17-4 PH Stainless Steel
17-4 PH Stainless Steel needs a larger inside bend radius (typically 2-3× thickness) and more springback compensation than mild steel.
For estimating, a 100 × 100 × 10 mm block of 17-4 PH Stainless Steel weighs about 0.78 kg.
