100% martensitic stainless steel, the X35 ST+ is developed for the manufacture of watch movement components. It offers excellent skills for bar turning, cutting, polishing and rolling. The X35 ST+ can replace traditional stainless steel as well as leaded and lead-free steels, and will also offer very good corrosion resistance.
Many diverse and varied components are now prescribed in X35 ST+ by watch manufacturers: screws, screw feet, studs, winding rods, nucleus, ratchet, barrel shaft, second pinion, balance pin, pins, various other pinions and pins.
