Stainless Steel 316 Bolt Nut

High-performance fasteners noted for their outstanding corrosion resistance, particularly in chloride and maritime conditions, are SS 316 bolt and nut sets. These fasteners are made to function dependably in extremely corrosive environments, like saltwater applications, chemical processing facilities, and coastal building. Compared to conventional 304-grade fasteners, SS 316 is substantially more durable and stronger due to the addition of molybdenum (Mo). To meet the diversified needs of the industry, Stainless Bolt Industries manufactures and supplies SS 316 bolts and nuts in a range of sizes, thread types, and finishes. The oil and gas, petrochemical, marine, food processing, pharmaceutical, and heavy engineering industries all make extensive use of them.

Stainless Steel Nuts

Overview of the SS 316 Bolt Nut

SS 316 bolt and nut pairs are designed to function exceptionally well in harsh and corrosive conditions. Because molybdenum (Mo) is present in the alloy, these fasteners, which are made from stainless steel grade 316, have improved resistance to pitting, crevice corrosion, and chemical exposure. Because of this, they are perfect for use in offshore structures, chemical processing, marine applications, the food and beverage sector, and pharmaceutical equipment. In situations where ordinary stainless steel might not hold up, SS 316 fasteners offer long-lasting dependability in addition to strength and durability.

Key Features of SS 316 Bolt & Nut:

The stainless steel nuts provided by us are enriched with the following features.

  • Superior Resistance to Corrosion Excellent corrosion, pitting, and crevice corrosion resistance makes it perfect for chemical and marine situations.
  • Improved Composition has a 2-3% molybdenum content, which makes it more durable than SS 304 in severe, chloride-rich environments.
  • High Yield and Tensile Strength Under extreme stress, it retains exceptional mechanical strength and load-bearing capacity.
  • Outstanding Resistance to Temperature operates dependably at temperatures as high as 870°C (1700°F) and as low as 1600°F.
  • When annealed, non-magnetic appropriate for uses like delicate equipment or electronics that call for non-magnetic characteristics.
  • Adaptable Use To accommodate a range of industrial uses, they are offered in different sizes, head types, and thread shapes.
