Al Summan Metals, a well-regarded manufacturer and supplier based in Dubai, UAE, distinguishes itself as a leading source of high-quality Alloy Steel AISI 4145 Bars. Recognized for its precision engineering and strict quality control, Al Summan Metals guarantees that its products satisfy international standards for strength, durability, and performance. The Alloy Steel AISI 4145 Bars are produced using advanced metallurgical methods and are subjected to comprehensive testing for consistent mechanical properties, ensuring dependability even in demanding industrial environments. With a firm emphasis on customer satisfaction and innovation, Al Summan Metals has emerged as a preferred option across the construction, oil & gas, and heavy machinery industries, both within the UAE and abroad.
The composition of Alloy Steel AISI 4145 Bars consists mainly of carbon (0.43–0.48%), manganese (0.75–1.00%), chromium (0.80–1.10%), molybdenum (0.15–0.25%), and nickel (0.30–0.60%), together with minor quantities of silicon and sulfur. This combination produces a balanced blend of strength, toughness, and wear resistance. The steel offers a tensile strength between 850 and 1000 MPa, a yield strength of roughly 650 MPa, and remarkable impact toughness. Owing to its outstanding hardenability and fatigue resistance, AISI 4145 preserves its structural integrity even under elevated stress and temperature conditions, making it ideal for demanding mechanical applications.

Nitronic 40 bars come in both rough and smooth finishes, based on the manufacturing method and what the customer requires. Smooth finishes are common for uses that call for improved aesthetics or precision.
Nitronic 40 rods come in diameters from 3mm to 300mm. Available finishes are bright, polished, black, and rough-turned, serving both industrial and decorative uses.
Nitronic 40 bar can indeed be welded through conventional techniques such as TIG, MIG, and shielded metal arc welding. There is no need for preheating, and annealing after welding guarantees the best properties.
Alloy Steel AISI 4145 Bars are broadly employed across industries that demand high strength, toughness, and fatigue resistance. They are especially well-suited for producing drilling tools, shafts, gears, couplings, and connecting rods found in oil and gas exploration equipment. Beyond that, these bars are extensively used in heavy-duty machinery, construction equipment, and automotive components subjected to considerable stress. Their exceptional hardenability and wear resistance make them perfect for applications requiring durability and precision. Whether in mechanical engineering or power generation, AISI 4145 Bars from Al Summan Metals deliver reliable performance and a lengthy service life in demanding industrial settings.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
