Navgraha Steel & Engg Company is a supplier and exporter of SS 321 Fasteners. We manufacture high quality SS 321 Fasteners with premium quality raw materials. Our company offer many types of fasteners like nuts, bolts, rings, washers and Screws. The different shapes of fasteners have different functions.
What is a fastener?
The fastener is a device to join two or more objects. Using this fastener, we create a non-permanent connection. We remove these connections due to any defect or damage due to this fastener. We manufacture fasteners using stainless steel 321 grade.
What is the Chemical composition of SS 321 Fasteners?
The material for the 321 grade is made up of carbon, chromium, iron, manganese, nitrogen, 9% nickel, phosphorus, sulfur, silicon and titanium. The small amount of titanium is added to the fasteners for stabilization.
What is the advantages of SS 321 grade?
Stainless Steel 321 is a firm alloy of stainless steel. This alloy offers the main advantage of excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation. By the addition of titanium, this alloy is stabilized against chromium carbide formation. Stainless Steel 321 alloy shows good toughness at low temperatures. SS 321 has resistance to many organic chemicals and sterilizing solutions. It also shows resistance to various inorganic chemicals. This alloy is not hardened by heat treatment but hardened by cold working.
The features of our Stainless Steel 321 Fasteners:
High creep and stress rupture properties, and it shows high corrosion resistance. These fasteners have good forming and welding characteristics. Our Stainless Steel 321 fasteners show excellent resistance to oxidation and have good creep strength.
Applications of our SS 321 Fasteners are as follows:
Our company supply these fasteners in various industries like marine industries, food processing industries and oil and gas industries. Our fasteners have high strength at high temperature, so it is used in various applications. It is also used in textile industries, transportation pipelines and energy sector industries. Our SS 321 Fasteners have amazing qualities like tensile strength, high strength, ductility, durability, flexibility, and formability.
