Punit Fasteners is a well-known manufacturer and supplier of Stainless Steel 316 Washers based in Delhi, India. We pride ourselves on delivering top-notch components that excel in applications where corrosion resistance and strength are crucial. SS 316 is an austenitic stainless steel alloy that’s enriched with molybdenum, giving it remarkable resistance to pitting, crevice corrosion, and general corrosion, especially in environments rich in chlorides and acids. Our SS 316 Washers come in a variety of sizes, thicknesses, and surface finishes, making them perfect for use in chemical plants, marine settings, food processing facilities, and pharmaceutical equipment.
Typically, Stainless Steel 316 Washers contain 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. This specific blend boosts their corrosion resistance, particularly in marine and chloride-heavy environments. These washers boast high tensile strength (around 515 MPa), excellent formability, and toughness, even in colder temperatures. Their non-magnetic properties and outstanding weldability make them suitable for both structural and non-structural applications.
