Harsh Metalloys is a renowned manufacturer and supplier of Stainless Steel 416 fasteners, operating from Mumbai, India. With the reputation for providing high-performance and precision-engineered fastening solutions, we serve diverse industrial needs in India and worldwide. Our SS 416 fasteners are produced from high-quality raw materials and sophisticated machinery to provide reliability, corrosion resistance, and dimensional accuracy. Based on a top priority on quality, timely delivery, and customer satisfaction, Harsh Metalloys has achieved a well-established position as a supplier of trustworthy stainless steel fasteners for the automotive, aerospace, industrial machinery, and engineering industries.
Stainless Steel 416 fasteners are manufactured using a martensitic stainless steel alloy containing a majority of chromium (12-14%), with the inclusion of sulfur to enhance machinability. This composition provides the alloy with moderate corrosion resistance, good machinability, and fair mechanical strength. SS 416 fasteners have a tensile strength of approximately 550 MPa and yield strength of about 275 MPa. They are also magnetic in nature and have medium resistance to oxidation. They have a mix of machinability and mechanical properties that positions them for precision-engineered uses in moderately corrosive environments.

We assure quality and safe delivery of our Stainless Steel 416 Fasteners. These fasteners are tested for rigorous performance. Different tests are undertaken, including tensile strength, corrosion resistance, and dimensional accuracy tests, to ensure the durability and functionality of the fasteners. For packing, we use the best protective packing material for securely packing fasteners, ensuring the fasteners are free from damages during the trade process. The fasteners are anti-corrosively wrapped, containerized and packed in strong boxes or crates labeled with all product details for safe and efficient worldwide delivery.
Stainless Steel 416 fasteners find extensive use in applications where high machinability and medium corrosion resistance are needed. These are valve parts, pump parts, gears, automotive parts, and machine tool parts. Because they can be machined easily to close tolerances, SS 416 fasteners are best suited for high-volume production. They also find applications in food processing machinery, firearms, and industrial automation systems. Though not acceptable for very corrosive or marine use, their ease of manufacture and cost-effectiveness render them the preferred option in a wide range of general-purpose engineering and mechanical uses.
