ASTM A36 Hot Rolled Carbon Steel Round Bar | Solid Mild Steel Rods Supplier

Premium ASTM A36 hot-rolled carbon steel round bars from China. Featuring excellent weldability, machinability, and high structural strength. Available in various diameters with custom straight-length cutting services. Widely used in structural construction, bridge engineering, fastener manufacturing (bolts & nuts), grates, and general fabrication/machining.

AISI/SAE 1045 C45 Round Steel Bar

This medium-carbon tempered steel (1045/C45) offers excellent strength and machinability under hot/cold working conditions. It can be quenched, tempered, or precision-machined to create high-precision parts like shafts, gears, and mechanical fasteners—perfect for industries demanding durability and dimensional accuracy.

A105 Round Steel Bar

An ASTM-specified carbon-manganese steel (similar to AISI 1330 but with lower silicon), A105 is the standard for forged steel pipe fittings. Its excellent machinability and strength make it essential for oil and gas pipeline systems, ensuring leak-proof, durable connections.

A572/S355JR Round Steel Bar

A572 steel bars have good strength, ductility and workability, making them ideal for structural applications. These characteristics make the A572 relatively simple to shape into different structures, while maintaining the ability to withstand large stresses and loads.
