Andre Stainless, based in Pulau Ujong, Singapore, is a leading supplier and producer of Stainless Steel XM19 Nuts that provides top-notch fastening services to diverse industries. Known for our accuracy in engineering and reliable quality, we provide critical industries with the products that provide superior corrosion resistance, high strength, and durability that lasts longer. Engineered for use in harsh environments, our XM19 nuts are designed to handle the demanding requirements of marine, chemical, and oil and gas uses. Focused on innovation, reliability, and on-time delivery, Andre Stainless remains the go-to partner for stainless steel solutions in Singapore and worldwide.
Stainless Steel XM19 Nuts are produced using a nitrogen-strengthened alloy having 20.5–23.5% chromium, 11.5–13.5% nickel, manganese, and 1.5–3% molybdenum along with the addition of nitrogen for added strength. These nuts have a tensile strength of up to 100 ksi, yield strength of 55 ksi, and great toughness and fatigue durability. XM19 has improved pitting and crevice corrosion resistance and is best suited for aggressive and high-temperature conditions. Relative to 316 stainless steel, XM19 nuts provide enhanced strength, better fabricability, and higher oxidation resistance, making them dependable for use in both industrial and offshore environments.
