SS 308 Fasteners presented by Navgraha Steel & Engg Company are extensively corrosion-resistant. These are widely applicable in variable pressures and temperatures. It is widely selected for marine high thermal applications. It is excellent working with long time exposure to several corrosive atmospheres. It is stocked with a range of standard sizes as well as custom size fasteners are readily available. Specifications and standards defined for these fasteners are widely selected for a number of applications. It is highly strong, and admirable durability is provided. Some of the types of fasteners are depending on sizes, shapes and thicknesses. It contains several types of nuts, bolts, washers, anchors, cap screw, deck screw, socket screw and others.
Stainless Steel SS 308 is austenitic steel enhancing the hardness of these fasteners. Thus these are tough in severe conditions. It is opposed to the chloride pit effect, and the surface is rust free with an excellent finish. It is unaffected by decomposition in atmospheric conditions.
It is easily applied with excellent adaptability and is removable for system dismantle. It provides strength and stability to the system. It is low maintenance due to withstand several harsh conditions with an effective working. Its high formability and ductility material reduces its cost and increases rapid production.

SS 308 Fasteners are excellently immune to decomposition in chloride ion surroundings as well as it is marine water decay resistant and best suited in marine applications. These are proposed with excellent strength and weldability. It works in high temperatures and stops stress rupture due to exceptional heat resistance. Most organic and inorganic chemicals causing corrosion are resisted with efficient working, and thus, these fasteners are allowed in chemical processing applications. It is effectively working in both flowing and steady seawater, providing excellent strength. Thus these fasteners are used effectively in marine, chlorides and salts.
