Harsh Metalloys, located in Mumbai, India, has earned a solid reputation as a reliable manufacturer and supplier of high-performance Stainless Steel Nuts. These nuts are specifically designed for secure fastening in various industrial, commercial, and structural applications. Made from top-quality stainless steels like 304, 316, 310, 321, and 904L, our products boast impressive strength, corrosion resistance, and durability. We offer a range of types, including hex nuts, lock nuts, flange nuts, and cap nuts, all produced to meet international standards such as ASTM, DIN, and ISO. Harsh Metalloys proudly serves industries like construction, oil & gas, marine, food processing, and chemicals around the globe.
Stainless Steel Nuts are generally made up of 18–25% Chromium and 8–22% Nickel, with some variations incorporating Molybdenum (found in 316/904L) to boost corrosion resistance. The mechanical properties differ by grade; for instance, 304 nuts have a tensile strength of about 515 MPa, while 316 nuts reach around 580 MPa, with yield strength typically falling between 205 and 260 MPa. These nuts are known for their outstanding resistance to oxidation, pitting, and stress corrosion cracking. They also maintain their mechanical integrity across a wide temperature range, offer excellent weldability, and comply with strict mechanical and chemical standards for demanding and corrosive environments.

Yes, stainless steel nuts can be welded, but the process requires proper preparation and equipment. Ensuring the right welding method and parameters is key to maintaining their strength and corrosion resistance.
Yes, we provide ss nuts standard and customized dimensions and polishes to meet your specific project requirements. For more details mail us on sales@www.harshmetalloys.com
Stainless steel nuts can be magnetic depending on the grade. Austenitic stainless steels (e.g., 304, 316) are typically non-magnetic, while ferritic and martensitic grades (e.g., 430, 410) are magnetic.
Yes, stainless steel nuts can be used for underground applications due to their corrosion resistance. However, the specific grade chosen should be suitable for the environmental conditions, such as moisture and soil composition.
Stainless Steel Nuts play a crucial role in fastening systems across various industries, thanks to their impressive strength and resistance to corrosion. You’ll find them in a multitude of applications, from pipelines and machinery to marine equipment, structural steelwork, chemical processing units, and even food-grade installations. These nuts work hand-in-hand with bolts, studs, and washers to create secure, vibration-resistant connections. When it comes to marine and coastal environments, 316 and 904L nuts are the go-to choices because of their exceptional resistance to chlorides. In sectors like food, pharmaceuticals, and beverages, the hygienic and easy-to-clean nature of stainless steel makes these nuts perfect for maintaining sanitary conditions. Their ability to withstand mechanical and environmental stress guarantees a long-lasting, maintenance-free performance.
