Al Summan Metals, headquartered in Dubai, UAE, is a premier manufacturer and supplier recognized for its superior-quality **Stainless Steel 440C Square Bars and Rods**. These items are prized for their exceptional hardness, resistance to wear, and capacity to endure corrosion. Every bar and rod is carefully engineered to comply with international standards, guaranteeing outstanding performance in demanding environments where durability and strength are essential. Owing to their high carbon and chromium composition, 440C stainless steel provides remarkable hardness and edge retention, making it ideal for components subjected to friction and wear. Al Summan Metals’ 440C Square Bars and Rods are used across a range of industrial, mechanical, and tooling applications, offering dependable and enduring performance.
These Stainless Steel 440C Square Bars and Rods are made up of roughly 16–18% chromium and 0.95–1.2% carbon, together with small quantities of manganese, silicon, and molybdenum. This distinctive composition lends them remarkable hardness, corrosion resistance, and wear resistance. They feature mechanical properties such as a tensile strength between 760 and 1,000 MPa, hardness ratings of 58–60 HRC, and moderate ductility, achieving an excellent balance of toughness and strength. The material’s martensitic structure delivers outstanding edge retention and fatigue resistance, making it an ideal option for high-stress and high-wear industrial components.

Yes, Stainless Steel 440C Square Bars exhibit magnetism. The reason is that they belong to the martensitic stainless steel category, which has a high carbon content, giving them ferromagnetic properties.
Yes, Stainless Steel 440C square rods are capable of being heat-treated to enhance their hardness and strength. The standard heat treatment procedure consists of austenitizing, quenching, and tempering.
Stainless Steel 440C square bars deliver outstanding strength at high temperatures and retain their hardness and wear resistance under elevated heat. That said, extended exposure can cause a slight decline in toughness and ductility.
Al Summan Metals’ Stainless Steel 440C Square Bars and Rods find broad use in industries where hardness and wear resistance matter most. They’re ideal for making bearings, valves, knives, cutting tools, and precision instruments. Beyond that, they work well in shafts, fasteners, and wear-resistant parts for machinery running under heavy stress. Their blend of corrosion resistance, hardness, and dimensional stability makes these bars and rods well suited to marine, chemical, and industrial applications, ensuring durable performance and reliability even in demanding conditions.
We provide products supplied with both mill test certificates and third-party test certificates, guaranteeing the finest standards of quality and compliance.
