316L Stainless Steel Round Bar - Bright Annealed Rod

QIDAMT · STAINLESS STEEL BAR

316L Stainless Steel Round Bar – Bright / Recozido

Low-carbon molybdenum austenitic stainless round bar for marine, chemical and pump shaft applications where pitting resistance is critical.

316L stainless steel round bar is the low-carbon version of 316, with 2 – 2.5 % molybdenum added. It offers superior pitting and crevice corrosion resistance over 304, especially in chloride and marine environments, and is the standard choice for pump shafts, fasteners and chemical equipment.

Key Advantages

Pitting Resistant

Mo addition gives PREN ≥ 24, excellent in chloride environments.

Low Carbon

≤ 0.030 % C prevents sensitization after welding.

Machinable

Good machinability, suitable for automatic lathes and CNC.

Bright Surface

Polished / bright annealed surface, ready for machining.
