Harsh Metalloys, a prominent manufacturer and supplier based in Mumbai, India, offers top-grade Stainless Steel XM19 Fasteners known for their exceptional strength, corrosion resistance, and superior durability. Also referred to as Nitronic 50, XM19 fasteners are engineered for high-performance applications where both mechanical and corrosion-resisting properties are critical. These fasteners are widely used in industries such as marine, petrochemical, pharmaceutical, and food processing. Available in various types like bolts, nuts, washers, studs, and screws, Harsh Metalloys ensures each product meets stringent international standards, offering reliability and precision to customers worldwide.
Stainless Steel XM19 Fasteners are primarily composed of high levels of chromium (20–23%), nickel (11–13%), manganese (4–6%), nitrogen (0.2–0.4%), and molybdenum (1.5–3%). This unique composition gives XM19 its remarkable resistance to corrosion, pitting, and stress corrosion cracking. The fasteners exhibit tensile strength exceeding 100 ksi (690 MPa), superior to that of 316 and even some nickel alloys. They maintain excellent strength and ductility across a broad temperature range, along with non-magnetic behavior even after cold working—making them ideal for demanding and corrosive service environments.
