Emilio Stainless stands out as a trusted manufacturer and supplier of Stainless Steel 440B fasteners right here in Manila, Philippines. We specialize in high-performance fastening solutions that are built for strength, durability, and precision. Our dedication to excellence and strict adherence to international standards means that our SS 440B fasteners are perfect for critical applications where high hardness and wear resistance are a must. Renowned for our reliable service and consistent quality, we proudly support a variety of industries across the Philippines with fasteners that excel in mechanically demanding and high-load environments.
The Stainless Steel 440B fasteners we produce are made from a high-carbon martensitic stainless steel alloy, featuring around 16–18% chromium and 0.75–0.95% carbon. After undergoing heat treatment, this alloy reaches impressive hardness levels (55–58 HRC) and tensile strength of up to 740 MPa. While it does offer moderate corrosion resistance, its standout features are its exceptional wear resistance, remarkable mechanical strength, and stability under heavy loads. These fasteners are perfectly suited for applications that require secure fastening in high-friction or high-impact situations.
