The company proudly serves various industries, including automotive, aerospace, tooling, and mechanical engineering, ensuring timely delivery and consistent quality of 440B nuts throughout Malaysia and Southeast Asia.
Stainless Steel 440B Nuts are crafted from a high-carbon martensitic stainless steel alloy, which includes Carbon (0.75–0.95%), Chromium (16–18%), and small amounts of Manganese, Silicon, and Molybdenum. After undergoing heat treatment, these nuts achieve impressive Rockwell hardness levels of 58–60 HRC, offering outstanding strength, wear resistance, and dimensional stability. While they provide moderate corrosion resistance in controlled environments and maintain their mechanical performance under thermal stress, 440B nuts are not the best choice for highly corrosive or marine conditions. However, they shine in precision fastening applications where hardness and durability are essential.
