Latham Steel, located in Hamilton, New Zealand, stands out as a top manufacturer and supplier of Stainless Steel XM19 Forgings. They specialize in crafting high-quality forged components that are built for strength, corrosion resistance, and reliability. XM19 is a high-performance austenitic stainless steel, perfect for applications that need to withstand chloride stress corrosion cracking and high temperatures. Thanks to Latham Steel’s cutting-edge forging techniques and rigorous quality control, every component they produce meets international standards, delivering durable and precise solutions for demanding sectors like chemical processing, oil and gas, and marine engineering.
When it comes to composition, Stainless Steel XM19 Forgings typically contain around 18–20% chromium, 12–14% nickel, 2–3% molybdenum, along with trace amounts of nitrogen and manganese. This blend offers outstanding resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking, all while maintaining impressive tensile strength, usually between 750–850 MPa, and yield strength around 250–350 MPa. Plus, XM19 forgings boast good toughness and ductility across a wide temperature range, making them suitable for both structural and high-performance applications.
