Alloy Steel Hollow Bars are strong and versatile steel products used in mechanical, structural, and industrial applications. Manufactured by Filiz Steel in Istanbul, Turkey, these bars are made from premium alloy steel with added elements like chromium, molybdenum, and nickel for superior strength, toughness, and durability. Hollow bars are cylindrical with a hollow center, which reduces weight while maintaining structural integrity. They are precision-engineered to meet strict industrial standards, making them ideal for applications where strength-to-weight ratio, durability, and performance under pressure are critical. Alloy Steel Hollow Bars are widely used in automotive, machinery, and engineering industries.
Alloy Steel Hollow Bars are made from carbon steel alloyed with chromium, molybdenum, nickel, and small amounts of manganese and silicon. This composition provides high tensile strength (typically 600–850 MPa), excellent yield strength, toughness, and wear resistance. They can withstand heavy loads, high pressure, and elevated temperatures without deforming. Hollow bars also offer good machinability, weldability, and fatigue resistance. The combination of lightweight structure and mechanical strength ensures reliable performance in demanding industrial, mechanical, and structural applications.
