Louis Metals provides premium Stainless Steel XM19 Forgings (Nitronic 50) from its Houston plant to meet demanding applications that involve higher strength and corrosion resistance. XM19 (UNS S20910) is high-strength austenitic stainless steel with outstanding pitting, crevice, and chloride stress corrosion resistance. Our forgings are manufactured in accordance with modern forging practices and satisfy or surpass ASTM A182 and ASTM A276 standards. Being endowed with high yield strength as well as excellent weldability, XM19 is best suited for challenging environments in the marine, chemical, and aerospace industries. Louis Metals supplies forged forms such as flanges, shafts, rings, and special profiles with expedited delivery options.
XM19 consists of 20–23.5% chromium, 11–13% nickel, 4–6% manganese, 1.5–3% molybdenum, and nitrogen (0.2–0.4%). It possesses tensile strength up to 965 MPa and yield strength of over 690 MPa — twice that of 316 stainless steel. XM19 has good toughness and non-magnetic characteristics even at low temperatures. It also demonstrates high resistance to corrosion in saltwater and acid conditions, with satisfactory fatigue strength. Louis Metals guarantees accurate heat treatment and forging techniques for uniform mechanical behavior and surface finish.

The forging process for Stainless Steel XM19 typically takes several hours, depending on the size and complexity of the part. Heating, shaping, and cooling stages contribute to the overall duration.
The ideal temperature range for forging Stainless Steel XM19 is between 2100°F to 2200°F (1149°C to 1204°C). It's important to maintain proper cooling to avoid distortion or cracking.
Yes, Stainless Steel XM19 (a high-strength alloy) can be forged into custom shapes. It offers excellent formability, allowing manufacturers to create parts with specific dimensions and designs as needed.
Stainless Steel XM19 Forgings are extensively applied in marine hardware, pump shafts, pressure vessels, and fasteners for underwater and chemical exposure. Their superior strength-to-corrosion resistance ratio qualifies them for naval, oil & gas, and desalination machinery. In the pharma and food sectors, it provides a corrosion-resistant, hygienic solution for valves and pumps. XM19 also finds its application in landing gear of aircraft, actuators, and energy products. The non-magnetic nature of XM19 is beneficial in electronic and nuclear applications. Louis Metals provides forged XM19 shapes and sizes in different forms customized for both dynamic and static load-bearing applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
