Chuck Metals, located in Singapore on Pulau Ujong, stands out as a top supplier and manufacturer of high-quality 1140 Steel Bars and Rods. They serve a variety of industrial sectors with precision-engineered carbon steel solutions. SAE 1140, a medium carbon steel enriched with sulfur, is renowned for its enhanced machinability, solid strength, and wear resistance. Chuck Metals offers 1140 steel bars and rods in multiple sizes and conditions, including cold drawn or turned & polished, all while meeting industry standards like ASTM A29. These bars find their place in automotive, machinery, agricultural equipment, and general engineering applications that require moderate strength and machinability.
SAE/AISI 1140 Steel is a medium-carbon steel characterized by a typical chemical composition of 0.37–0.44% Carbon, 0.60–0.90% Manganese, and about 0.08–0.13% Sulfur, which enhances machinability. It boasts a tensile strength of roughly 620–780 MPa, a yield strength of around 415–515 MPa, and an elongation of 12–20%, depending on the heat treatment. 1140 steel also shows moderate toughness and decent wear resistance, making it suitable for cold working. However, due to its sulfur content, it has limited weldability and is generally not recommended for structural welding without specialized techniques.

1140 Steel Bars and Rods are commonly utilized in machined components, including shafts, gears, spindles, axles, bushings, and connecting rods, where moderate strength and good machinability are crucial. The sulfur-enhanced machinability makes this steel perfect for automatic screw machines and CNC operations that demand precise tolerances and high productivity. You’ll often find 1140 steel in the automotive, agricultural machinery, construction equipment, and tooling industries, delivering reliable mechanical performance at a competitive price. It’s particularly well-suited for parts that undergo turning, milling, or drilling, but it’s not ideal for heavily stressed structural components.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
