VT machining offers CNC Swiss Machining for 1144 Steel (UNS G11440 / Stressproof-type), typically supplied cold-drawn, stress-relieved. High-strength free-machining steel with low distortion after machining.
CNC Swiss Machining Notes for 1144 Steel
1144 Steel is well suited to Swiss-type turning for small, long parts in volume, with short cycle times from bar.
For estimating, a 100 × 100 × 10 mm block of 1144 Steel weighs about 0.79 kg.
