Zeron 100 SA keys are super duplex stainless steel machine keys (UNS S32760) used to lock rotating elements (gears, pulleys, couplings, impellers) onto shafts. Patterns: parallel keys per DIN 6885 / ISO 2491, Woodruff per DIN 6888, gib-head per DIN 6887. SA matches the corrosion envelope of the matching shaft / coupling / impeller so the keyway interface stays corrosion-stable for equipment lifetime, critical in seawater pumps, marine winches, FGD damper drives, desalination motor couplings.
