Harsh Metalloys, a reputable manufacturer and supplier based in Mumbai, India, specializes in high-quality Stainless Steel 416 Nuts that are crafted for exceptional machinability and strength. SS 416 is a free-machining martensitic stainless steel, making it perfect for parts that need extensive machining and moderate resistance to corrosion. Our SS 416 nuts are made in line with international standards like ASTM and DIN, ensuring they are reliable and precisely dimensioned. These nuts find their place in mechanical assemblies, automotive parts, and industrial machinery where precision and durability are key. We provide a variety of sizes, threads, and finishes to meet different application needs.
Stainless Steel 416 Nuts are composed of about 12–14% Chromium, with Sulfur (at least 0.15%) added to boost machinability. The carbon content is between 0.15–0.30%, which allows for heat treatment that can achieve a hardness of up to 40 HRC. These nuts show moderate tensile strength (around 550–700 MPa) and good wear and galling resistance. Although SS 416 has lower corrosion resistance compared to austenitic grades, it performs well in less severe environments. Its machinability and ability to be heat-treated make it a popular choice for precision fastening in high-volume production settings.
