Carbon Steel AISI 1045 Angle is a tough, high-strength structural product that’s a go-to in engineering and fabrication where durability and wear resistance are key. Made from medium carbon steel, this angle strikes a great balance between strength, hardness, and machinability. It’s crafted with precision, ensuring accurate dimensions and a clean surface finish, which makes it perfect for detailed structural work. AISI 1045 angles are trusted for their reliability under load and their performance in challenging environments, making them a top choice for industrial, mechanical, and construction projects.
Carbon Steel AISI 1045 Angle is a medium-carbon steel product made from AISI 1045 steel, consisting primarily of 0.45% Carbon, 0.60-0.90% Manganese, 0.04-0.10% Silicon, ≤0.040% Phosphorus, and ≤0.050% Sulfur. The alloy possesses good strength, toughness and wear resistance. AISI 1045 steel possesses excellent machinability and hardness properties, which render it ideal for usage in applications requiring higher strength and toughness. Angle is widely utilized in construction and manufacturing, and its structural support is applied in a variety of projects.

This angle is primarily made of iron, with about 0.45% carbon, plus manganese and small amounts of sulfur and phosphorus. That higher carbon content boosts its strength and hardness compared to low carbon steels. Mechanically, it delivers solid tensile strength, yield strength, and wear resistance. It also responds well to heat treatment, enhancing its hardness and overall performance. While it has moderate weldability, its machinability and structural integrity make it a strong candidate for heavy-duty applications.
You’ll often find Carbon Steel AISI 1045 Angle in structural frameworks, machinery parts, supports, and heavy fabrication tasks. It’s ideal for making brackets, frames, shafts, and load-bearing structures across construction, automotive, and industrial sectors. Thanks to its strength and durability, it’s also used in power plants, material handling equipment, and engineering assemblies. Its ability to handle stress, impact, and wear makes it perfect for applications that need robust and long-lasting structural support.
