Luois Metals, located in Houston, USA, stands out as a top manufacturer and supplier of premium 1035 Round Bars, delivering dependable carbon steel solutions for a variety of industrial, construction, and automotive needs. SAE/AISI 1035 is a medium carbon steel celebrated for its impressive strength, toughness, and machinability. Luois Metals offers 1035 round bars in different diameters and conditions, including hot-rolled, cold-drawn, and normalized, all adhering to standards like ASTM A29. These bars are perfect for applications that require moderate strength and excellent wear resistance, such as shafts, bolts, gears, and automotive parts.
When it comes to composition and mechanical properties, 1035 Round Bars generally contain about 0.32–0.38% carbon and 0.60–0.90% manganese, with minimal phosphorus and sulfur. This blend results in moderate tensile strength (570–700 MPa) and yield strength around 370 MPa in the hot-rolled state, which can be enhanced through heat treatment. 1035 is known for its good machinability and formability, and it can be hardened via heat treatment or surface hardened through flame or induction methods. This alloy is ideal for applications that need moderate hardness, impact resistance, and wear performance while remaining easy to process.

In terms of uses and applications, 1035 Round Bars are extensively utilized in the automotive, construction, and general engineering fields for parts that demand moderate strength and durability. Typical applications include axles, crankshafts, studs, gears, hydraulic shafts, and various machine components. Its versatility also makes it a great fit for agricultural equipment, forged tools, and mechanical linkages. When heat treated, 1035 steel provides enhanced wear resistance, making it suitable for medium-stress, repetitive-load applications. It’s often chosen as a cost-effective alternative to alloy steels for components that don’t require high-performance metallurgy but still need reliable strength and toughness.
