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, 和 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.
