Alloy Steel A105
Alloy Steel A105
Apar Alloys, a trusted Stockist and Supplier of premium alloy steel materials, offers Alloy Steel A105, a high-quality carbon steel renowned for its excellent strength, toughness, and weldability. Specifically designed for applications requiring good fatigue and impact resistance, this grade is widely used across pressure vessels, flanges, fittings, and industrial piping, providing reliable performance in critical load-bearing and high-pressure components.
With consistent mechanical properties and good hardenability, Alloy Steel A105 delivers reliable performance under normalized or stress-relieved conditions. The carefully controlled carbon content ensures superior resistance to wear, abrasion, and moderate temperature deformation, making it ideal for precision-engineered components, pressure-critical parts, and structural applications where durability, reliability, and long service life are essential.
