Based in Cairo, Egypt, Khaled Stainless is a trusted name when it comes to manufacturing and supplying Stainless Steel 440B bolts, perfect for high-strength and precision-critical applications. These bolts are crafted from top-notch martensitic stainless steel and undergo advanced heat-treatment processes, ensuring they deliver outstanding hardness, wear resistance, and precise dimensions. Khaled Stainless caters to various sectors, including automotive, machinery, valves, pumps, and industrial equipment, both in Egypt and beyond. By adhering to ASTM and EN standards and offering tailored sizes, threading, and finishes, the company provides fastening solutions designed for the toughest mechanical environments.
Stainless Steel 440B is a martensitic stainless steel that contains around 0.75–0.95% carbon and 16–18% chromium. This unique blend allows SS 440B bolts to achieve impressive hardness and tensile strength after heat treatment, while also offering better toughness than 440C. They excel in wear and abrasion resistance, boast good fatigue strength, and provide moderate corrosion resistance in less harsh environments. While SS 440B bolts are magnetic and great for high load-bearing applications, they do have limited weldability and ductility compared to austenitic stainless steel grades.

Quality control tests both destructive and non-destructive are conducted by our quality control team after manufacturing the Stainless Steel 440B Bolts. Advanced tools and techniques are used for testing in order to assure the client’s performance and longevity. When these bolts pass the tests, we package them correctly with relevant materials to conserve their quality during transport. We have ensured they reach the clients on time with no delays and make available all the necessary documentation at the time of delivery for full transparency.
Stainless Steel 440B bolts are ideal for applications that demand strength, rigidity, and wear resistance. You’ll find them in pumps, valves, compressors, tooling equipment, precision machinery, and heavy-duty mechanical assemblies. They’re also commonly used in automotive and industrial equipment that faces high mechanical stress and friction. SS 440B bolts perform best in dry or mildly corrosive settings, so they’re not the best choice for marine or highly acidic environments, making them perfect for controlled industrial applications.
