Khaled Stainless, located in Cairo, Egypt, has built a solid reputation as a reliable manufacturer and supplier of Stainless Steel 440 bars, perfect for high-strength and precision engineering needs. Crafted from top-quality martensitic stainless steel, these bars are celebrated for their impressive hardness, wear resistance, and precise dimensions. Khaled Stainless offers a range of SS 440 bars, including the 440A, 440B, and 440C variants, catering to various sectors such as tooling, automotive, machinery, valves, and industrial equipment, both in Egypt and beyond. With a strong focus on quality control, heat-treatment capabilities, and adherence to ASTM and EN standards, the company ensures that its materials meet the demands of rigorous mechanical applications.
Stainless Steel 440 belongs to the martensitic stainless steel family and boasts a high carbon content (around 0.65–1.20%) along with 16–18% chromium. The specific properties differ among the 440A, 440B, and 440C variants, with 440C providing the highest level of hardness. After undergoing heat treatment, SS 440 bars achieve remarkable tensile strength, outstanding wear and abrasion resistance, and commendable fatigue performance. They are magnetic and offer moderate corrosion resistance in less aggressive environments. While their toughness and weldability may be limited, their mechanical strength and hardness are exceptional.
