VT machining offers CNC Press Brake Forming for 440C Stainless Steel (UNS S44004 / 1.4125 / SUS440C), typically supplied annealed or hardened. Highest hardness/wear resistance of stainless; hardened parts are finish-ground.
CNC Press Brake Forming Notes for 440C Stainless Steel
440C Stainless Steel bends to a tight inside radius (about 1× thickness) in this condition.
For estimating, a 100 × 100 × 10 mm block of 440C Stainless Steel weighs about 0.77 kg.
